This long essay on global warming and climate change is suitable for students of classes 7,8,9 and 10, and also for competitive exam aspirants.The Ozone layer is a layer that covers the Earth and acts as a protective cover from the harmful Ultra Violet rays or UV rays of the sun. This layer also helps to maintain the temperature on the planet to let life sustain on the planet. Recently, the world has changed the balance of the Ozone layer and the planet. Here, we are talking about global warming and climate change.Over the last few decades, planet Earth has heated up a lot. This is called the phenomena of global warming, which means the warming up of the globe, i.e., Earth. Since we now live in theage of development and capitalism, there are factories all over the world that emit harmful fumes. These fumes are an example of the kind of substances that create the holes in the Ozone layer. These holes allow in harmful UV rays and heat the planet.There are several reasons for global warming and climate change. The primary reason for global warming and climate change is the greenhouse effect. The greenhouse effect refers to the entrapment of heat by greenhouse gases, such as carbon dioxide, nitrous oxide, etc. between the Ozone layer and the surface of theEarth, creating more and more heat as it remain trapped. This causes the temperature on the Earth to rise increasingly.Greenhouse gases come into the air in several ways, which are all human-made. The fumes emitted by factories, smoke released by vehicles and factories, and other instances of the burning of fossil fuels are >causes of global warming and climate change. Deforestation is one more reason for the same, as cutting down trees means more carbon dioxide in the air than there was before they were cut down.As a result of global warming and climate change, the icecaps and glaciers around the world are melting, thereby increasing the sea level. Many islands have even become fully submerged due to the rising water levels. Extreme climatic conditions cause many people to die due to heat strokes caused by heatwaves, droughts, etc. Global warming and climate change have also caused many natural disasters, such as forest wildfires, tsunamis, floods, etc.Global warming and climate change have now reached a point where it is almost irreversible.There are a few things that we can do personally to help contain global warming and climate change. Since vehicle emissions play a large contributing role, we can consider using modes of transport other than cars, such as walking, cycling, and public transport. Spreading awareness about global warming and climate change is one of the most important things.All in all, global warming and climate change is a terrible human-made phenomenon. We must acknowledge the damage that we, as a species, have done to our planet. It is important to understand what global warming and climatechange are and to do our best to stop it from increasing more and more.Short Essay on Global Warming and Climate Change 200 Words in EnglishBelow we have given a short essay on global warming and climate change of 200 words. Short essay on global warming and climate change is suitable for students of classes 1,2,3,4,5 and 6.Global warming is a critical problem in the world today. It means that our planet is heating up more by the day.The Ozone layer protects the Earth from harmful ultraviolet rays of the sun. If this layer gets holes in it, it can be very dangerous for our planet. There are many gases in the air, such as carbon dioxide and nitrous oxide, which make holes in the Ozone layer, and because of this, our planet is becoming hotter. These gases come from cars, buses, trucks, factories, etc. Deforestation also adds more of these gases to the air.Global warming and climate change mean that the icy glaciers are melting and increasing the water level. There are many natural disastersbecause of global warming, like floods, tsunamis, droughts, etc.It is vital to become aware of global warming and climate change and make other people aware of it. We must do anything we can to stop it from increasing.10 Lines About Global Warming and Climate Change EssayGlobal warming refers to the heating up of Earth due to human activitiesThe Ozone layer protects us from harmful UV raysThe Ozone layer is depleting by the day, because of toxic gases and fumes produced on Earth (mostly by humans)The primary cause of global warming is the greenhouse effect, i.e., the entrapment of greenhouse gases between the Ozone layer and the surface of the Earth, creating more heat by the daySources of greenhouse gases include CFCs, burning of fossil fuels (such as to power enginevehicles), agriculture (methane produced by farm animals), factory fume emissions, etc.Due to global warming, there have been several natural disasters, such as forest fires, cyclones, etc.The sea levels are rising by the day because the planet is getting hotter, which is dangerous as it has submerged many lands.It is imperative to stop global warming and climate change or try our best to curb it.Using public transport instead of private vehicles per person is an alternative to try out to help curb global warming.It is essential to spread awareness about global warming and climate change. >FAQ’s on Essay On Global Warming And Climate ChangeQuestion 1.What does it mean by global warming and climate change?Answer:Global warming refers to the heating up of the Earth due to the depletion of the Ozone layer, the greenhouse effect, and the fumes and gases being emitted continuously by different sources on Earth. It is incredibly harmful not only for the planet but also for living beings on the Earth.Question 2.What does it mean by the greenhouse effect, and how does it relate to global warming?Answer:In literal terms, the greenhouse effect refers to when gas comes from outside a plant greenhouse gets entrapped within the greenhouse, and remains inside to create moisture and heat. This same effect can be seen between the Earth’s surface and the Ozone layer, where hot UV rays enter through ozone holes and get trapped inside the Earth.Question 3.What are the consequences of global warming and climate change?Answer:Global warming has several consequences, such as the melting of glaciers, which leads to rising sea levels. Natural disasters increase in volume and intensity, etc. Global warming and climate change also create hotter weather leading to higher death rates.Question 4.What can I do on my part to curb global warming?Answer:One of the most important things you can do to curb global warming is changing your mode oftransport from personal vehicles to public transport spread the word about it, i.e., make people more aware, etc.。
碳中和四级英语作文Carbon Neutrality。
With the increasing awareness of climate change and environmental protection, carbon neutrality has become a hot topic in recent years. Carbon neutrality refers to achieving a balance between the amount of carbon dioxide emitted into the atmosphere and the amount removed from it. It is a crucial step in combating global warming and reducing greenhouse gas emissions.To achieve carbon neutrality, individuals, businesses, and governments need to take actions to reduce their carbon footprint. This can be done through various means, such as using renewable energy sources, increasing energy efficiency, planting trees, and offsetting carbon emissions through carbon credits. By reducing carbon emissions and offsetting the remaining emissions, we can work towards a sustainable future for our planet.One of the key ways to achieve carbon neutrality is through the use of renewable energy sources, such as solar, wind, and hydroelectric power. These sources of energy are clean and sustainable, and they do not produce carbon dioxide emissions when generating electricity. By transitioning to renewable energy sources, we can significantly reduce our carbon footprint and move closer to carbon neutrality.Another important way to achieve carbon neutrality is by increasing energy efficiency. This can be done by using energy-efficient appliances, insulating buildings, and reducing energy waste. By using energy more efficiently, we can lower our carbon emissions and contribute to a more sustainable environment.Planting trees is also a crucial step in achieving carbon neutrality. Trees absorb carbon dioxide from the atmosphere and store it in their biomass, helping to reduce the amount of carbon dioxide in the atmosphere. By planting more trees and preserving forests, we can help to offset carbon emissions and promote biodiversity.Offsetting carbon emissions through carbon credits is another way to achieve carbon neutrality. Carbon credits are a way for individuals and businesses to invest in projects that reduce or remove carbon emissions from the atmosphere. By purchasing carbon credits, we can offset our own carbon emissions and support projects that help to combat climate change.In conclusion, achieving carbon neutrality is essential in the fight against climate change. By reducing our carbon footprint, transitioning to renewable energy sources, increasing energy efficiency, planting trees, andoffsetting carbon emissions, we can work towards a more sustainable future for our planet. It is up to all of us to take action and make a difference in the fight against climate change. Let us work together towards a carbon-neutral future.。

围绕可持续发展碳循环绿色发展写英语作文全文共3篇示例,供读者参考篇1Going Green to Save Our PlanetHave you ever heard of words like "sustainable development", "carbon cycle", and "green growth"? They may sound like big complicated terms, but they are really important ideas that we all need to understand. Our planet Earth is an amazing place, filled with beautiful nature, diverse plants and animals, and all the resources we need to live happy, healthy lives. But unfortunately, we humans haven't been taking very good care of our home lately.For a long time, we've been using up the Earth's natural resources faster than they can be replaced. We cut down too many trees, we pollute the air and water, and we waste energy and materials carelessly. This isn't sustainable - it can't continue forever without causing big problems. If we keep going like this, we'll run out of important things we need, and the planet will become an unhealthy, polluted place to live.One of the biggest issues is something called the carbon cycle. Carbon is a type of chemical element that is found everywhere on Earth - in the air we breathe, the ground we walk on, the plants and animals, and even our own bodies. Carbon constantly moves through the environment in a cycle - it gets released from some places and absorbed in others through natural processes.But human activities like burning fossil fuels (coal, oil, and natural gas), agriculture, and deforestation release extra carbon dioxide and other greenhouse gases into the atmosphere. Too much of these gases can trap extra heat from the sun, causing global warming and climate change that harms the environment.So what can we do about it? That's where sustainable development and green growth come in. Sustainable development means meeting our current needs without compromising the ability of future generations to meet their needs. It's about finding ways to have a good quality of life, economic growth, and opportunities, while also protecting the environment and conserving natural resources.Green growth is the idea of developing our economies and improving our quality of life in environmentally sustainable ways. It focuses on using natural resources efficiently, reducingpollution and greenhouse gas emissions, conserving energy and water, and finding new clean and renewable sources of energy. The goal is to transition to a low-carbon, resource-efficient, and socially inclusive economy.There are lots of ways we can incorporate sustainable development and green growth into our daily lives, schools, communities and countries. At home, we can reduce, reuse, and recycle as much as possible. Turn off lights and electronics when not in use to save energy. Walk, bike or use public transportation instead of driving when you can. Eat more plant-based foods and less meat. Plant trees and gardens. At school, set up recycling programs, start an environmental club, and learn about environmental issues.Businesses and governments can do their part too - by investing in clean energy like solar and wind power, energy efficient buildings and transportation, sustainable agriculture and forestry practices, and new green technologies. We all need to work together to take better care of our one and only planet!It may seem like one person can't make much of a difference, but every little action adds up. If we all adopt more sustainable habits and make green choices, it will have a huge positive impact on our world. We have the knowledge and ability to makechanges, we just need to put it into action for the sake of the environment and future generations. Let's protect the beautiful natural world around us and create a healthier, greener, more sustainable tomorrow. Our planet is counting on us!篇2Our Planet Needs Our HelpHi there! My name is Emma, and I'm 10 years old. I love playing outside, exploring nature, and learning about our amazing planet Earth. But lately, I've been hearing a lot of grown-ups talk about something called climate change, and it sounds really serious.Climate change is basically when the Earth's temperature gets warmer than normal. This can happen because of things like burning too many fossil fuels (like coal, oil, and natural gas) and cutting down too many trees. When we burn fossil fuels, it releases a gas called carbon dioxide into the air. And when we cut down trees, there are fewer trees to absorb that carbon dioxide. Too much carbon dioxide in the air is not good for our planet!You see, the Earth has this natural cycle called the carbon cycle. It's kind of like a big circle where carbon moves betweenthe air, plants, soil, and even the ocean. Plants take in carbon dioxide from the air and use it to grow, while animals (like us!) breathe out carbon dioxide. When plants and animals die, their bodies decompose and release carbon back into the soil and air.But now, because of all the fossil fuels we're burning and trees we're cutting down, there's too much carbon dioxide in the air. And that extra carbon dioxide is trapping more heat from the sun, making the Earth warmer than it should be. This warming is causing all sorts of problems, like melting glaciers, rising sea levels, more extreme weather like hurricanes and droughts, and even making it harder for plants and animals to survive in their natural habitats.That's why it's so important for all of us to work together to protect our planet and help fight climate change. We need to find ways to live more sustainably, which means living in a way that doesn't harm the environment too much.One way we can do this is by using less fossil fuels and switching to renewable energy sources like solar, wind, and hydropower. These don't release as much carbon dioxide into the air. We can also plant more trees and protect forests, because trees are really good at absorbing carbon dioxide and helping the carbon cycle stay balanced.Another thing we can do is reduce, reuse, and recycle as much as we can. When we throw away too much stuff, it ends up in landfills or the ocean, which can hurt plants and animals. But if we reuse or recycle things instead of throwing them away, we can save energy and resources. We can also try to buy products that are made from recycled materials or come in less packaging.At school, we're learning about being more energy-efficient, too. We can turn off lights and electronics when we're not using them, and our school is even looking into getting solar panels to use clean energy from the sun. We're also planting a school garden, which will help absorb carbon dioxide and provide us with fresh fruits and vegetables.It might seem like a lot of work, but we all have to do our part to protect our planet. Even small changes can make a big difference! Maybe you can start a recycling program at your school or in your neighborhood. Or you could plant a tree or start a garden with your family. Every little bit helps!I know it can be scary to think about climate change and all the problems it's causing. But I also know that if we all work together and make smart choices, we can help keep our planet healthy for generations to come. We're the future, and it's up to us to take care of the Earth.So let's get out there and be eco-warriors! Let's find ways to live more sustainably, reduce our carbon footprint, and keep the carbon cycle balanced. Our planet is an amazing place, and it's our job to protect it. Who's with me?篇3The Earth is Our HomeOur beautiful planet Earth is the only home we have. It's a wonderful place, filled with amazing plants, animals, and natural wonders. From the tallest mountains to the deepest oceans, the Earth has so much to offer. But our planet needs our help to stay healthy and green.You've probably heard about things like climate change, global warming, and pollution. These are big problems that are causing harm to the Earth. The good news is, we can all do our part to take better care of our planet. By learning about important topics like sustainability, the carbon cycle, and green growth, we can make a positive difference.What is Sustainability?Sustainability means meeting our current needs without compromising the ability of future generations to meet their own needs. In other words, we should use the Earth's resourceswisely so that there will be enough for everyone, now and in the future.One way to be sustainable is to reduce waste. We can do this by recycling, reusing, and reducing the amount of stuff we buy and throw away. For example, instead of buying a new toy, you could borrow one from a friend or trade one of your old toys. Or, you could make your own toys from recycled materials like cardboard boxes or plastic bottles.Another way to be sustainable is to conserve energy. We can do this by turning off lights and electronics when we're not using them, and by using energy-efficient appliances. We can also try to walk, bike, or take public transportation instead of driving, which saves fuel and reduces air pollution.The Carbon CycleYou might have heard about the carbon cycle, which is the path that carbon takes as it moves through the Earth's systems. Carbon is an element that is found in all living things, as well as in the air, water, and soil.Plants play a very important role in the carbon cycle. Through a process called photosynthesis, plants take in carbondioxide from the air and use it to make their own food. They then release oxygen back into the air for us to breathe.When plants and animals die, their bodies decompose, and the carbon they contain is released back into the soil or water. This carbon can then be absorbed by other living things, and the cycle continues.However, human activities like burning fossil fuels (like coal, oil, and natural gas) and cutting down forests are disrupting the natural balance of the carbon cycle. This is causing too much carbon dioxide to build up in the atmosphere, which contributes to climate change and global warming.Green GrowthTo help protect our planet, we need to focus on green growth. Green growth means finding ways to create jobs and grow our economies while also protecting the environment.One way to achieve green growth is by using renewable energy sources like solar, wind, and hydroelectric power. These sources of energy are better for the environment because they don't produce as much pollution or greenhouse gases as fossil fuels.Another way to support green growth is by choosing products and services that are eco-friendly or sustainable. For example, you could buy locally-grown fruits and vegetables, which don't have to travel as far and use less fuel for transportation. Or, you could choose toys and clothes made from recycled materials or natural fibers like cotton or bamboo.Governments, businesses, and communities are also working on green growth initiatives. These might include things like building energy-efficient buildings, investing in public transportation, and creating more parks and green spaces.What Can You Do?As a kid, you might be wondering what you can do to help protect the Earth and support sustainability, the carbon cycle, and green growth. The good news is that even small actions can make a big difference!Here are some things you can do:Reduce, reuse, and recycle. Be mindful of the amount of waste you create and try to find ways to reuse or recycle items instead of throwing them away.Save energy. Turn off lights and electronics when you're not using them, and encourage your family to do the same.Plant a tree or a garden. Trees and plants help absorb carbon dioxide and produce oxygen, which is good for the environment.Walk, bike, or take public transportation when possible. This reduces the amount of greenhouse gases and pollution from cars and buses.Learn more about environmental issues and share what you've learned with your friends and family.Participate in Earth Day events or join an environmental club at your school.Encourage your parents or guardians to make eco-friendly choices when shopping or choosing products and services.Every little bit helps, and by working together, we can make a big difference in protecting our planet for generations to come.The Earth is an amazing place, and it's up to all of us to take care of it. By being mindful of sustainability, understanding the carbon cycle, and supporting green growth, we can ensure that our planet stays healthy and beautiful for years to come. Let's all do our part to take care of the Earth – our one and only home.。
如何保护环境英语演讲稿通用三篇如何保护环境英语演讲稿 1Good evening, ladies and gentlemen. My topic is “Give environment more care". I’d like to talk about some global environmental problems, share some of my stories and show you some data in my speech.At the beginning, I’d like to ask you a question.Has your hometown’s environment been polluted, if it has, raise your hands please? (Thank you)Let me give you an impression of my hometown. That is a small village of Yunnan province. There are many mountains, forests and rivers. If you go there, I promise you will be amazed by its beautiful landscape. Because you just can touch the nature with your fingers and feelings. You can enjoy the blue sky, flying birds, waterfall, amazing sunset and many other sceneries. When I was a teenager, I often climbed these mountains and jumped into clear and clean river for a swim with my peers. However, after my graduation from high school, I came to Beijing for college. I found something different. Because when I raised my head, the sky’s color was not blue, but yellow. When I looked down, dirty and poisonous rivers are full of unrecyclablerubbish and giving out unpleasant smells. When I looked forward, so many people wore their mouth masks. Everyone here plains weather and environment. It seems so inharmonious between man and nature. Why?As we know, in the past few centuries, human have made countless remarkable achievements in science and technology to explore the mysterious world better. Conquering nature with powerful tools, people have achieved material prosperity. Meanwhile, environment has been badly damaged. So a series of severe problems e along, such as species extinction, energy cr__, incurable diseases, the three main pollutions etc. All of these factors bring our beautiful planet disasters, humanity as well. Let me show you some statistics. According to the report from World Wide Fund for Nature, the species of entire world have declined by 52 % since 1970. That means about 75 kinds of precious species disappear forever from the Earth each day. In addition, scientists claimed that human now need one and a half Earth to meet the demand for natural resources. Another frightening data from the UN in 2012, there are almost 8.4 million people around the world who die of cancers caused by environmental issues every year. It is so horrible, isn’t it? Man has taken too much from nature, alsopaid such a heavy price for it. If we don’t try to change these situations, what will happen one or two centuries later?But, fortunately, the majority throughout the world are aware of the significance of environmental protection. Much many individuals, environmentalists and organizations have taken actions spontaneously. Companies donate part of their profits to support some green projects. Moreover, Government has carried out many policies to conserve endangered species, support green industries and encourage people to live a green life. From a global perspective, though it is a long journey to make the Earth recovered and to live in harmony with it, I do believe that, with everyone’s efforts, we will finally get there.Ladies and gentlemen. For ourselves, for our children, and for all human beings, by the end of my speech, I do hope you can keep the following words in mind __ The nature’s prosperity is humanity’s prosperity. Caring environment is caring human’s future. Lives need be valued by us, nature need be respected by us, and the Earth need be loved by us, please give them more care. (Thank you very much. Ladies and gentlemen.)如何保护环境英语演讲稿 2The way to world’s future-low carbon life “low-carbon” isone of the most popular buzz-words in this year. Not only China but all countries focus on the topic of “low-carbon”.Here, I’d like to share my own experience abroad with you. Several years ago, I was very lucky to have an opportunity to live in the Australia about half a month. During that time, Not only did I enjoy the beautiful natural scenery there, but also I appreciated the people’s active way of protecting their environment. Now, whenever the environment protection is mentioned, the beautiful scenery of Australia will arise in my mind, white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and lovely squirrels playing happily among the trees.As a citizen of China, if everyone can actively protect the environment in our daily life and if we would like to reduce our carbon footprint, the scenery of blue sky, green grass and lovely animals in Australia will appear in China, even in HeFei. But I totally support the view, that is to say, Emotion without action is irrelevant! Do you unplug electronics after you use them? Do you switch off everything before you go to sleep? Do you adjust your TV screen a bit dimmer to save energy? Do you re-use water for different activities around the house? Each of these seeminglyinsignificant adjustments in your daily life can make a difference in saving the environment of tomorrow.We all know that nothing is more fortable than sitting in the warmth of a hearted car while it’s snowing a nd hailing outside in the freezing cold。
Unit 4 Global warmingThe Arctic will soon be free from ice,experts say.The change is sure to take place,but global warming and climate change are changing the earth’s landscape(地形) rapidly,causing anxiety worldwide.Experts say that the Arctic sea ice is melting quite faster than expected and it can affect not just the region,but Earth in general.A scientist even says that next year,or maybe the year after that,the Arctic will be free of ice.Peter Wadhams,director of the Scott Polar Institute in Cambridge,said,“Most people expect this year will see a record low in the Arctic’s summer sea ice cover.Next year or the year after that,I think it will be free of ice in summer and by that I mean the central Arctic will be icefree.” “You will be able to cross over the North Pole by ship,” he added.Wadhams’ study says that melting sea ice will have a great influence on the planet since the sea ice is more capable of reflecting(反射) sunlight compared to water that can only reflect 10% of the sunlight.Once the sea ice melts,the water can only reflect a small amount of sunlight.This means that the Earth will receive and absorb more sunlight,making the planet even hotter.The year 2016 had already broken records of the hottest temperature ever recorded and the trend doesn’t seem to show any decrease in global warming.“It doesn’t look like the ice is healing and growing back,” Tom Wagner,NASA’s manager said in a report.Like Wadhams,scientists and researchers all over the world are lecturing around to educate people to help lighten global warming that has already changed the planet’s landscape.判断正(T)误(F)1.The speed of the Arctic sea ice being melting is beyond expectation.(T) 2.The Arctic won’t be free from ice soon because of global warming and climate change.(F)Period One Warming Up & Reading—Prereading匹配左边的单词与右边的汉语意思[第一组]1.consume A.n.燃料2.random B.vi.同意;捐赠;订阅3.phenomenon C.vt.消费;消耗;耗尽4.subscribe D.adj.胡乱的;任意的5.fuel E.n.现象答案 1.C 2.D 3.E 4.B 5.A[第二组]6.quantity A.vt.反对;反抗7.oppose B.n.量;数量8.state C.n.大灾难;浩劫9.trend D.n.趋势;趋向;走向10.catastrophe E.vt.陈述;说明答案 6.B 7.A 8.E 9.D 10.C[第三组]11.range A.n.洪水;水灾12.consequence B.n.旱灾;干旱13.mild C.n.结果;后果;影响14.flood D.adj.温和的;温柔的;淡的15.drought E.n.种类;范围答案11.E 12.C 13.D 14.A 15.B[第四组]16.famine A.vi.趋向;易于;vt.照顾;护理17.data B.n.资料;数据18.byproduct C.n.化石19.tend D.n.饥荒20.fossil E.n.副产品答案16.D 17.B 18.E 19.A 20.CStep 1FastreadingSkim the text and do the following exercises.1.This article may be from .A.an environmental magazineB.a diaryC.a novelD.a story答案 A2.Find out the main idea of each paragraph.Para.1 A.the cause of the earth’s beco ming warmerPara.2 B.the consequence of burning fossil fuelsPara.3 C.the increase of carbon dioxidePara.4 D.global warming will go onPara.5 E.puzzles about global warmingPara.6 F.different attitudes to global warmingPara.7 G.an introduction to the passage答案Para.1:G Para.2:A Para.3:B Para.4:C Para.5:D Para.6:F Para.7:E Step 2CarefulreadingRead the text carefully and choose the best answer.1. made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997.A.Dr Janice FosterB.Charles KeelingC.George HambleyD.Sophie Armstrong答案 B2.Some scientists like George Hambley think that the temperature increase will .A.cause a rise of several metres in the sea levelB.cause the spread of diseases and the disappearance of speciesC.encourage a greater range of animalsD.cause severe storms,floods,droughts and famines答案 C3.The main difference between Dr Janice Foster’s theory and George Hambley’s lies in .A.how to prevent global warmingB.what causes global warmingC.whether global warming would cause serious problems or notD.whether the levels of carbon dioxide have increased or not over the years答案 C4.Which of the following is TRUE according to the text?A.Greenhouse gases refer to some byproducts of the burning of fossil fuels.

英语作文二氧化碳排放的危害及建议全文共6篇示例,供读者参考篇1The Big Bad Carbon Dioxide MonsterHi, my name is Alex, and I'm a 10-year-old kid who loves playing outside and exploring nature. But lately, I've been hearing a lot about something called "carbon dioxide emissions," and how it's causing big problems for our planet. At first, I didn't really understand what all the fuss was about, but after doing some research, I realized it's a pretty serious issue that we all need to pay attention to.So, what exactly is carbon dioxide, and why is it such a big deal? Well, carbon dioxide is a gas that's released into the air whenever we burn things like gasoline, coal, or natural gas for energy. It's also produced when we cut down trees and forests, which are super important for absorbing carbon dioxide. The problem is, when there's too much carbon dioxide in the air, it traps heat from the sun and causes the Earth's temperature to rise. This is called the "greenhouse effect," and it's causing ourplanet to get warmer and warmer, which can lead to all kinds of scary consequences.One of the biggest dangers of too much carbon dioxide in the air is climate change. You've probably heard about this before, but in case you haven't, climate change is basically a fancy way of saying that the Earth's weather patterns are changing in weird and unpredictable ways. This can cause things like rising sea levels, more intense storms, droughts, and heat waves. Imagine your favorite beach being completely underwater, or your neighborhood being hit by a massive hurricane or tornado! That's the kind of stuff that could happen if we don't do something about篇2The Dangers of Too Much Carbon Dioxide and What We Can DoHi, my name is Jamie and I'm ten years old. Today I want to talk to you about something really important that is affecting our planet - too much carbon dioxide (CO2) in the air. You might have heard about carbon dioxide on TV or from your teacher. It's a gas that gets released when we burn fossil fuels like coal, oil and natural gas for energy.Why is too much CO2 a problem? Well, it's one of the main gases that causes global warming and climate change. Global warming is making the Earth get hotter overall. Climate change means the weather patterns are shifting and becoming more extreme and unpredictable in many places.Both global warming and climate change are very dangerous for the planet and all the people, animals and plants that live on it. Let me tell you some of the scary impacts:Rising Sea LevelsAs the Earth gets warmer, the ice at the North and South Poles is melting faster. All that melted ice flows into the oceans, making the sea levels rise higher and higher. Islands and coastal cities could someday be flooded and millions of people might have to leave their homes.Extreme WeatherWith climate change, we are seeing more intense hurricanes, wildfires, droughts, floods and heat waves happening in different parts of the world. These extreme weather events are terrifying and cause lots of damage and disruption. Many people can get hurt or displaced from their homes.Plants & Animals Going ExtinctRapid climate change makes it very hard for some plants, animals and other species to adapt quickly enough to survive. Their habitats and food sources are being destroyed. Scientists think thousands of species could go extinct if we don't do something about climate change soon.Food & Water ShortagesIncreasing temperatures, changing rain patterns and natural disasters harm crop production in many regions. This could lead to not enough food for the growing human population. Water supplies are also being threatened by droughts, flooding and rising salt levels.It sounds pretty scary, doesn't it? I get worried when I think about the future if we don't fix this problem. The good news is that there are things we can do to reduce carbon dioxide emissions and fight climate change. Here are some of my suggestions:Use Less EnergyOne of the biggest sources of CO2 pollution comes from burning fossil fuels to make electricity. We can cut emissions by using less energy overall. Things like turning off lights when not in use, taking shorter showers, unplugging devices when notbeing used, and setting thermostats to use less heating and air conditioning can make a big difference.Walk, Bike or Take Public Transit MoreCars, trucks, planes and other vehicles that run on gasoline create a lot of CO2 pollution. Whenever possible, we should walk, bike or take buses and trains to get around instead of driving a car. It's good exercise too!Eat More Plant-Based FoodsThe animals used for meat production create high levels of greenhouse gases. Cutting back on meat consumption, especially red meat, and eating more plant-based foods can substantially lower your carbon footprint.Reduce, Reuse, RecycleMaking new products from raw materials generates greenhouse gas emissions. We can cut back on waste by reducing what we consume, reusing items when we can, and recycling paper, plastic, glass and metal. Buying secondhand items is another great way to reuse instead of making new.Plant TreesTrees absorb and store CO2 as they grow. Planting more trees is an effective way to remove carbon dioxide from the atmosphere. Getting involved in community tree planting initiatives can make a big positive impact.Support Renewable Energy SourcesFossil fuels release a lot of CO2 when burned, but renewable energy sources like solar, wind and hydro power don't. We should push companies and governments to invest more in clean, renewable energy and move away from fossil fuels over time.Every one of us, including kids, needs to do our part to fight climate change and reduce carbon pollution. It will take a huge, global effort, but the future of planet Earth and all its inhabitants depends on it. Our leaders and adults have to act now before it's too late. We are counting on them to find solutions and protect our environment. After all, we kids have no other home than this one planet to grow up on. We have to take care of it!篇3The Scary Problem of Too Much Carbon DioxideHi everyone! My name is Jamie and I'm 10 years old. Today I want to talk to you about a very serious problem that affects the whole world - too much carbon dioxide (CO2) in the air!What is Carbon Dioxide?Carbon dioxide is a gas that is created whenever anything burns. When we burn things like gasoline, natural gas, coal, or wood, carbon dioxide gets released into the air. It's invisible so you can't see it, but it's there.Carbon dioxide is also produced when people and animals breathe out. And it gets released from plants and soil too. A little bit of carbon dioxide is normal and ok. But today, there is way too much carbon dioxide building up in the Earth's atmosphere (the blanket of air around our planet).Why is Too Much CO2 a Problem?You might be wondering - so what if there's extra carbon dioxide, what's the big deal? Well, it turns out that too much CO2 is really dangerous for the Earth!Carbon dioxide is what we call a "greenhouse gas." This means it traps heat from the sun inside the atmosphere, kind of like a greenhouse used for growing plants. The more CO2 there is, the more heat gets trapped. This causes temperatures all overthe world to rise steadily higher and higher. We call this "global warming."Global warming leads to lots of scary changes to the planet. It's causing:Melting of glaciers and ice at the North and South PolesRising sea levels that flood coastal citiesExtreme weather like hurricanes, droughts, and heat wavesChanges in weather patterns that make it hard to grow cropsLoss of habitat for animals like polar bears and penguinsScientists have studied this issue very carefully. They are sure that the huge increase in CO2 over the last 100-150 years, caused by humans burning fossil fuels like oil, gas and coal, is the main driver of global warming. If we don't reduce our CO2 emissions soon, the Earth will keep getting hotter and face catastrophic consequences.What Causes High CO2 Levels?So where is all this extra carbon dioxide coming from? Here are some of the biggest sources:Vehicles like cars, trucks, trains and planes - They burn gasoline and other fossil fuels to operate, releasing CO2.Power plants that burn coal or natural gas - These provide electricity to homes and businesses but produce massive CO2 emissions.Factories and industries - Manufacturing items like steel, cement, and plastic results in a lot of CO2 being released.Cutting down forests - Trees absorb CO2 from the air, so deforestation means there are fewer trees to remove the gas.Agriculture and livestock - Cows, pigs and other farm animals release methane, another potent greenhouse gas.How Can We Reduce CO2 Emissions?Clearly, we need to find ways to cut back on our carbon dioxide output before it's too late! Here are some ideas:Use clean energy instead of fossil fuels - We should generate more electricity from solar panels, wind turbines, hydropower and nuclear power that don't produce CO2.Drive vehicles that don't use gasoline - Electric cars and trucks, as well as walking, biking or taking public transit, could replace polluting gasoline vehicles.Make buildings more energy efficient - Adding better insulation and windows can reduce the electricity needs for heating and cooling.Plant more trees - Trees absorb CO2 as they grow, so planting new forests is very helpful.Reduce, reuse and recycle - Manufacturing new products like plastic creates a lot of emissions. Reusing and recycling cuts down on waste.Switch to renewable energy sources - Things like solar panels on homes or geo-thermal heating don't create any CO2.Eat less meat - Cows and other livestock are a major source of methane emissions. Eating less meat would lower these levels.What Can Kids Do?Now you might be thinking - but I'm just a kid, what can I do to stop climate change? Actually, there are lots of ways kids can make a difference!At home:Turn off lights when leaving a roomTake shorter showers to save hot waterWalk, bike or take public transit instead of drivingUnplug electronics and chargers when not in useEat less meat and more vegetablesRecycle paper, plastic and glassPlant trees and gardensAt school:Form an environmental clubHave fundraisers to plant treesStart a recycling programEncourage teachers to conserve energySpread awareness about climate changeEvery little bit helps when it comes to reducing our carbon footprint. And kids can influence their parents and other adults too!I really hope world leaders, companies and regular people will start taking serious action against climate change soon. The future of the whole planet is at stake! We need to cut way down on our CO2 emissions to avoid global warming's worst effects. It will take a huge effort, but we have to try our best to save theEarth. Let's all work together to create a cleaner, greener world with less carbon pollution!篇4The Scary Problem of Carbon Dioxide EmissionsHave you ever heard of carbon dioxide (CO2)? It's a gas that's all around us, but too much of it can cause big problems for our planet. When we burn things like gasoline, coal, and natural gas, they release lots of carbon dioxide into the air. This is called carbon dioxide emissions.Why are carbon dioxide emissions so bad? Well, let me tell you!Carbon dioxide is a greenhouse gas. That means it traps heat from the sun inside our atmosphere, kind of like a greenhouse traps warm air inside to help plants grow. But too much of this trapped heat can make the Earth way too hot, which is not good for plants, animals, or people.This overheating of the Earth's atmosphere is called global warming. Global warming causes all sorts of scary things to happen!Melting Ice and Rising SeasAs the Earth gets hotter, huge chunks of ice start melting in places like the North and South Poles and on big glaciers. All this melted ice flows into the oceans, making the sea levels rise higher and higher. This can cause flooding in coastal cities and even whole islands to disappear under water!Extreme WeatherGlobal warming also makes the weather go crazy! We get more powerful hurricanes, tornadoes, blizzards, and other severe storms. There are more droughts (times with no rain at all) in some places and terrible floods in others. These extreme weather events can destroy homes, crops, and even entire communities.Harm to Plants and AnimalsThe changing climate also makes it hard for many plants and animals to survive. Some can't adapt to the new temperatures or weather patterns, so their habitats (the places where they live) become uninhabitable. This means some plant and animal species could go extinct, which means they would completely disappear from the Earth forever!So what can we do about this huge problem? Well, we need to cut down on our carbon dioxide emissions as much as possible. Here are some suggestions:Use Less EnergyOne of the biggest sources of carbon dioxide emissions is the burning of fossil fuels (like coal, oil, and natural gas) to make electricity. So we should try to use less energy at home and school. Turn off lights when you leave a room, unplug devices when you're not using them, and avoid wasting energy as much as you can.Choose Renewable EnergyInstead of dirty fossil fuels, we should use clean, renewable energy sources like solar power (from the sun), wind power (from windmills), and hydropower (from water). These don't produce any carbon dioxide emissions!Walk, Bike, or Take Public TransportationA lot of carbon dioxide also comes from cars, trucks, and other vehicles that burn gasoline. So whenever possible, walk, bike, or take public transportation like buses or trains instead of driving a car. It's better exercise and better for the environment!Reduce, Reuse, RecycleMaking new products often requires a lot of energy and creates carbon dioxide emissions. So we should reduce howmuch stuff we buy and use, reuse things instead of throwing them away, and recycle as much as possible.Plant TreesTrees absorb carbon dioxide from the air and produce oxygen that we need to breathe. So planting more trees can help remove some of that excess carbon dioxide from the atmosphere.If we all work together to cut our carbon dioxide emissions, we can help stop global warming from getting even worse. We need to take action now to protect our planet for the future! What will you do to reduce your carbon footprint (impact on the environment)? Every little bit helps save the Earth.篇5The Dangers of Too Much Carbon Dioxide and What We Can DoHave you ever heard of carbon dioxide or CO2? It's a gas that is all around us in the air we breathe. Some carbon dioxide is good because plants need it to grow through photosynthesis. However, there is a problem when there is too much carbon dioxide in the atmosphere. This can lead to global warming andclimate change, which is not good for the planet or any of the people, animals, and plants that live on it.Where does all this extra carbon dioxide come from? Mostly from burning fossil fuels like coal, oil, and natural gas. Fossil fuels are used to produce electricity, power our cars and trucks, heat our homes, and run factories. When these fuels burn, they release carbon dioxide into the air. Trees and plants can absorb some carbon dioxide through photosynthesis, but humans are burning way more fossil fuels than what plants can handle.So what's the big deal with having too much carbon dioxide building up? Well, it causes something called the greenhouse effect. Carbon dioxide is a greenhouse gas, which means it traps heat from the sun inside the Earth's atmosphere instead of letting it escape into space. It's kind of like when you get into a car that has been sitting out in the hot sun - it gets super hot inside because the heat can't escape through the windows. Too many greenhouse gases make the whole planet work like a greenhouse, causing temperatures to rise everywhere. This rise in global temperatures leads to climate change.Climate change causes all sorts of problems around the world:• Rising sea levels from melting glaciers and ice caps, which could flood coastal cities• More extreme weather like hurricanes, droughts, floods, and heatwaves• Disruptions to habitats that animals and plants depend on, causing some species to go extinct• Less freshwater availability in some regions• Impacts on agriculture and food suppliesThat all sounds pretty scary! The good news is that there are lots of things we can do to reduce our carbon footprint and the amount of carbon dioxide we release into the atmosphere.At School:• Walk, bike, take the bus, or carpool to school instead of having your parents drive you• Recycle pape r, plastic, glass and metal instead of throwing it away• Turn off lights when not in use• Don't waste food in the cafeteriaAt Home:• Turn off and unplug electronics when not using them• Take shorter showers• Walk or bike on sh ort trips instead of asking for rides• Eat more plant-based meals and less meat• Reduce, reuse, and recycle as much as possible - less waste = less CO2We can also plant more trees, which absorb carbon dioxide as they grow. Convincing adults to use renewable energy like solar and wind power instead of burning coal and gas is another great way to cut emissions.Some bigger changes we should work on:• Improving public transportation so fewer people need to drive• Designing more efficient and sustainable buildings• Developing electric vehicle technology• Finding ways to make manufacturing and industries more energy-efficientI know these can seem like small actions, but if everyone did their part it would make a huge difference! We need to protectthe planet for ourselves and future generations. Speaking up about climate change and sharing this knowledge with others is important too. With some effort, we can reduce carbon dioxide emissions and make the world a cleaner, healthier place.篇6Dangers of Carbon Dioxide Emissions and What We Can DoHi everyone! My name is Jamie and I'm 10 years old. Today I want to talk to you about something really important that affects every single person on planet Earth - carbon dioxide emissions.Carbon dioxide, or CO2 for short, is a gas that gets released when we burn fuels like gasoline, natural gas, coal, and oil. It's also released when we cut down trees and from other natural processes. A little bit of CO2 is okay, but too much of it is really bad for the environment and for all of us.You see, CO2 is one of the main gases that causes something called the "greenhouse effect." It lets the sun's rays in to heat up the Earth, but then traps that heat instead of letting it escape back into space. This causes temperatures all over the world to rise in a process we call "global warming."Global warming sounds kind of fun, like the whole planet is just getting a little warmer. But in reality, it's very dangerous! Here are some of the scary things global warming can cause:Melting ice caps and rising sea levelsThe North and South Pole have huge caps of ice on them. But as global temperatures rise, that ice is melting and turning into water that flows into the oceans. This makes the level of the oceans rise, which can cause flooding in coastal cities and islands. Millions of people could become homeless if sea levels keep rising.Extreme weather eventsAs the Earth gets warmer, the weather patterns we're used to get disrupted. This means more powerful hurricanes, tornadoes, blizzards, droughts, heat waves, and other intense storms. These extreme weather events can destroy homes, crops, and even cost lives.Plants and animals going extinctMany types of plants and animals can only survive in very specific climates and environments. As those climates change due to global warming, the plants and animals can no longer adapt and could completely die off, becoming extinct forever.This includes polar bears, coral reefs, frogs, puffins, and many others.Food and water shortagesChanging weather patterns means less predictable rainfall, which can dry up water sources that humans and animals need to survive. It also makes it harder for farmers to grow enough crops to feed everyone. This could lead to widespread famine and starvation.Spread of diseaseAs temperatures rise, disease-carrying insects like mosquitoes can expand their territory and infect people in new areas with illnesses like malaria, Zika, dengue fever, and others.Those all sound really scary, don't they? The good news is, there's still time for us to take action and stop global warming from getting even worse! But we all have to work together. Here are some things we can do:Use less energyA lot of the energy we use comes from burning fossil fuels like coal, oil and gas which release CO2. We can cut down our energy use by:Turning off lights when leaving a roomUnplugging electronics when not using themWalking, biking or taking public transport instead of drivingSetting thermostats a few degrees cooler in winter and warmer in summerReduce, reuse, recycleManufacturing new products like plastic bottles and aluminum cans releases tons of CO2. We can cut down on waste by:Using reusable bottles, bags, and containersRecycling paper, plastic, glass and metalDonating old clothes, toys and furniture instead of throwing them outComposting food scraps instead of sending them to landfills Eat less meatCows and other farm animals release a lot of methane, another potent greenhouse gas. We can reduce our carbon footprint by:Eating more fruits, veggies, grains and plant-based foodsOnly eating meat occasionally, not every dayBuying locally-grown and organic foods when possiblePlant treesTrees absorb CO2 from the air and produce oxygen that we need to breathe. We should plant more trees and protect forests by:Planting trees at home, school, or community gardensRecycling paper and wood productsSupporting organizations that prevent deforestationUse renewable energyInstead of fossil fuels, we can get energy from renewable sources like solar, wind, geothermal and hydroelectric power that don't produce CO2. We can:Install solar panels on our roofsUse energy-efficient LED light bulbsSupport policies that promote renewable energySpread awarenessFinally, we all need to keep learning about climate change and teach others about the importance of reducing emissions. We can:Do projects on the environment at schoolWrite to companies and leaders asking them to be more eco-friendlyCelebrate holidays like Earth DayUse social media to share facts about global warmingIf every person, family, school, and country does their part, we can work together to reduce harmful carbon emissions and stop global warming from getting worse. We only have one beautiful planet Earth - let's take care of it so we and future generations can enjoy it for many, many years to come!What do you think? Are you ready to take action against climate change? Let me know if you have any other great ideas!。

Difference Between Global Warming and Greenhouse Effect
Global Warming vs Greenhouse Effect
Global warming and greenhouse gases are two concepts that have been topics of heated discussion among environmentalists and those who are trying to save our planet from their detrimental effects. While these two concepts are intricately related like cause and effect, there are subtle differences that need to be highlighted for a better understanding of the readers.
In the simplest of words, global warming takes place when the rays of Sun are trapped within the atmosphere of Earth because of emission of many greenhouse gases such as carbon dioxide and methane. However, this explanation does not cover all the aspects and this is why we need to analyze the two terms closely. The fact of the matter is, greenhouse effect is not detrimental for us or the environment, and it is harmful only when it is in more than desirable amounts.
Greenhouse effect
Normally, the rays of sun coming down to earth are reflected back to outer space by the surface of the earth. Some of these reflected rays are trapped within the atmosphere surrounding earth by gases that make up earth’s atmosphere. This is known as greenhouse effect and is considered to be a natural and healthy phenomenon. The existence of this greenhouse effect is vital for maintaining life forms on earth. Had there been no greenhouse effect, earth would have become too cold to have any life.
Though greenhouse effect is vitally important for us, too much of it can be harmful for us. This is because an enhanced greenhouse effect means higher average temperatures of the surface of earth which is not good for our ecosystem. There is a very thin and delicate balance that needs to be maintained as neither the absence nor too much of greenhouse effect is good for life on earth.
Global warming
The average rise in temperature of earth’s surface over the last 50 years is termed as global warming. Now this global warming is a cumulative effect of many factors such as deforestation, pollution, burning of fossil fuels, and of course greenhouse effect that has been under the scrutiny of the entire world, especially the western world that has been blaming poor countries for higher emission levels of carbon dioxide and methane gases.
Global warming is not a natural phenomenon and has to do with the activities of mankind. This is why there have been so many conferences and summits between nations to come to terms with this problem. Industrialization process inevitably leads to global warming as to meet the growing energy demands of developing nations.
If we talk about differences between these two closely related concepts, it is clear that one leads to another though there are other many reasons for global warming. However, in comparison to other reasons, it is greenhouse effect that has hogged the limelight in recent years.。
