With the development of technology, our life has been greatly improved, at the same time it also brought harm to people. As a consequence, science and technology likes a double-edged sword, because it benefits human by promoting economic and social development, but it may have negative consequences for human survival and development under certain conditions.
★The Positive Effects Of Technology Development On Human Life
In many ways, Science and technology improve people's lives. In terms of medicine, the emergence of a variety of modern technologies saves the lives of many people. In terms of astronomy, meteorological satellites can accurately predict future weather changes over time, the production of human life; it provides convenience to the production of human life. From the aspect of human life, all kinds of electrical appliances make life comfortable, such as air conditioning. From the 21st century, science and technology, especially the rapid development of computer network technology and electronic information technology, makes mobile phones and computers entering the homes of people, and they become the
necessities of our lives. Especially the popularization of the computer, we can chat with friends and family on the internet; we can read news, watch movies and play games online; we can listen to the teacher in the class and check the information; now, online shopping is very popular, too.
Thus, we also must be admitted that science and technology is changing our life and culture in certain degree. The development of science and technology promote the process of human, and humans have this new and better life. The use of hi-tech technology make means of production become more modern, automated, which greatly improves production efficiency.
However, the drawback of technology is real; moreover, its presence is likely related to the fate of our planet.
★The Negative Effects Of Technology Development On Human Life
First, one of problems is the global warming. Due to a variety of the use of fossil fuels, greenhouse gases emissions produce the greenhouse effect, making global warming, leading melting of Arctic ice and anomalous climate.
The second is the formation of acid rain, as cars and factories that release a great deal gases, including some acid
gas. When it rains, they will form acid rain, which corrode buildings and hurt people’s skin.
Third, at present along with the rapid development of biological technology, biological safety problem has become a big proposition that influence economic and security and political of the whole country, the whole world .For example, SARS virus.
There are many problems. For instance, owing to advances in computer technology, young people abandoned their studies, they can not extricate themselves. Air conditioning and refrigerators also destroy our precious atmosphere.
◆As a consequence, science and technology is a double-edged sword. On the one hand, it can break backward, on the other hand it also bring human endless disaster.Its negative effects should not be overlooked, only if we don't go against nature of way in the fairness and justice of heart, we can make development of science and technology in right direction.
