Unit 9 Everybody Can Help the EnvironmentPart I Warming upTape-script: Part I1. Buy fresh food that doesn't need a lot of packaging.2. Try to buy "organic" fruit and vegetables from farmers whodon't use chemicals.3. Save as much water as possible.4. Use products that won't stay forever in the earth or sea when you throw them away.5. Use bottles more than once or take them to a bottle bank.6. Try to save paper. Also, buy and use recycled paper as often as possible.7. Avoid "throw-away" products.8. Make sure that your family and friends use unleaded petrol in their cars.9. Don't buy products (fur or ivory, for example) made from rare or protected species.10. Use public transportation as often as possible.11. If you're buying wood, don't choose hardwood from tropicalrainforests.12. Look for aerosols which haven't got any CFCs in them.13. Don't buy hamburgers or pizzas in plastic boxes which contain CFCs.14. Use batteries as little as possible. It takes 50 times more energy to make them than they produce.15. Don't leave on electric lights, TV, hi-fi, etc., if you're not using them.16. Find out more about Conservation issues in your area. Are there any woods or fields in danger, for example?17. Try to throw away at least 25% less rubbish.18. Help old people in your area to insulate their homes. This saves energy and helps to keep them warm in winter.19. Visit any local nature reserves or zoos and talk to the people who run them.Part II Campaign California Re. LeafA. Tapescript1. Time is not neutral. We are so rapidly depleting the atmosphere, we are so rapidly changing the climate, that unless we start now the situation may well become irreversible.2. Unless the environmental movement comes into everybody's life, in real simple activities, it's not ,going to work. Planting a tree is real simple. So I want to participate in something that is really accessible to the citizen, just to everyday people, to children. So that as citizens we can doa lot.3. It's one step in a combination of things. The other kinds of things that we can all be doing are being much more conscious about how we useenergy in our home, whether we're buying -- ah -- fuel efficient cars and products, whether we're using Styrofoam when we don't have to be, -- ah -- whether we're turning off light bulbs when we -- ah -- leave the room -urn -- and just a variety of personal actions like recycling, we need to start thinking about and doing more.B. How listen to the whole report, Answer the questions with key words.1.What is the focus of the party in San Francisco Washington SquarePark?planting single tree2. What is the purpose of the tree-planting campaign?deflate Greenhouse Effect/take COZ3. Why do you think Actor Peter Cyote took part in the tree planting ceremony and served as the master?real simple activities/accessible to people/citizen/do a lot4. Why are tree plantings important according to Isobel Wade?clean up CO2/ improve environment/ neighborhoods attractive5. Apart from tree planting, what other things do we need to start thinking about?a variety of personal actionsTapescript.Campaign California Re-Leaf as in L-E-A-F was kicked offrecently with a party in San Francisco's Washington Square Park thrown by a coalition of seven urban forestry groups. The focus of the party was the planting of a single tree, the first of 20 million to be planted in 40 Californian cities over the next decade. The tree planting campaign is an attempt to deflate what's being called the Greenhouse Effect. Scientists believe that the earth is getting warmer because of an accumulation of carbon dioxide in the air. Trees take carbon dioxide out of the air.Martin Rosen is the director of the Trust for Public Land, the organization that is coordinating the state-wide tree planting effort. "Time is not neutral. We are so rapidly depleting the atmosphere, we are so rapidly changing the climate, that unless we start now the situation may well become irreversible."Some movie stars were on hand for the tree planting ceremony. Actor Peter Cyote served as the master of ceremonies. "Unless the environmental movement comes into everybody's life, in real simple activities, it's not going to work. Planting a tree is real simple. So I want to participate in something that is really accessible to the citizen, just to everyday people, to children. So that as citizens we can do a lot. ' After Peter Cyote introduced a few speakers and a couple of songs were sung the ceremony moved over to a corner of the park where a group of youngsters planted a Copper Beech tree.Isobel Wade is the state coordinator for Campaign CaliforniaRe-leaf. Wade says the tree plantings are important because they will help clean up the carbon dioxide in the atmosphere, improve the environment and make neighborhoods more attractive, but Isobel Wade cautions it isn't enough, "It's one step in a combination of things. The other kinds of things that we can all be doing are being much more conscious about how we use energy in our home, whether we're buying -- ah -- fuel efficient cars and products, whether we're using Styrofoam when we don't have to be, -- ah -- whether we're turning off light bulbs when we -ah- leave the room -- um -- and just a variety of personal ?actions like recycling, we need to start thinking about and doing more."Isobel Wade also says she'd love to see everyone in California's urban areas take the time to plant one tree and take care of the ones that are already growing.Part III Steps to Improving RecyclingA.I. Raising public awarenessA. explaining the kinds of materials that can be recycledB. providing ways on how to properly dispose of the materialsC. educating the public on how to properly sort reusable materials from those that can't be recycled very easilyD. giving the public information they can graspII. Making technological progressExample: the development of a new manufacturing process-- helping remove ink from paper in more energy efficient and environmentally safe methodsIII. Increasing demand for recycled materialsB. Now Listen again. Complete the statements.1. Sometimes We become complacent when it comes to recycling, but when you speak in terms of actual facts and figures that everyone can understand, people become more cognizant of the problem.2. According to the talk, paper materials that are difficult to recycle include waxed paper, carbon paper and food wrappers.3. In some cases, recycling could be hazardous to the environment if special precautions are not taken because chemical waste is sometimes produced as a result.Tapescript:We hear it a lot in the news these days:"Recycle newspapers and save a tree. Collect bottles and cans so they can be reused in the manufacturing of new products. 'Let's use paper as an example. The first step is to raise public awareness about the recycling process, explain the kinds of materials that can be recycled, and provide ways on how to properly dispose of. them. Local governments should educate the public on how to properly sortreusable materials from those, like waxed paper, carbon paper, plastic laminated material such as fast food wrappers, that can't be recycled very easily. Then, a system of collecting these sorted materials needs to be established. Sometimes we become complacent when it comes to recycling, but when you speak in terms of actual facts and figures that everyone can understand, people become more cognizant of the problem.I remember reading one time that the energy saved from one recycled can can provide enough power to operate the television for three hours. Give the public information they can grasp, and then you will increase your chances of gaining followers.Second, technological progress has been made on many fronts. One breakthrough has been the development of a new manufacturing process to help remove ink from paper in more energy efficient and environmentally safe methods. Recycling paper materials can be expensive in both monetary and environmental terms. The difficulty in removing print from paper, the amount of energy expended during the process, and caustic waste that is sometimes produced are costs that companies incur that are then passed on to the consumer.The final key is to increase demand for the growing surplus of resources waiting to be recycled. This problem has appeared in various regions of the world where the technology to process the used materials lags far behind the amount being collected for recycling.Recycling is a crucial link protecting our planet. The three keys mentioned are important ways to achieve this end.。
