Ask and answer the questions in pairs.

1 Why do people at the beginning of the new millennium spend so much time and effort drawing public attention to the problem of ecology?

2 What ecological problems that humanity faces nowadays in your opinion are most urgent?

3 Why are scientists so much concerned about the greenhouse effect and the process of global warming?

4 Do you think global warming is caused by human activities?

Which of them?

5 Since the Industrial Revolution, which started more than 200 years ago, the need for energy has steadily increased, hasn't it? Why are people nowadays very much concerned about energy they use to light and heat homes , the energy that makes cars run, etc.?

6 It is a known fact that during the history of the Earth there were periods of dramatic climate changes, which occurred naturally, Ice Age among them. Why do you think scientists are so much concerned about the current climate changes?

7 Can you say that the climate in the place where you live is changing? How? Do you find these changes for the better or for the worse? Can you give examples of climate changes in other places of the planet?

8 Do you think the humankind can solve the world's ecological problems? If so, in what way?

9 Can individuals help in this area? What ways?

Male: Let's plant a tree in the back garden. It will be great for wildlife and it will give us some shade in the

summer.

Female: Oh, I don't know. Won't it be expensive , and a lot of hard work?

Male: Not really. I'll do all the digging. It'll look great when it's done, trust me. You're always talking about ways to help the environment well , this is a really good way to start .

Female : Oh, OK, then. What kind of tree

shall we get?

Male: What are you going to do about your car? It broke down again yesterday , didn't it?

Female: Yes. I'm not sure what to do. I

could sell it and buy a bike. Or I could try and fix it one more time.

Male: You know it will only break down

again. It always does!

Female: You're right. I'll sell it. That way I'll get fit and help the environment at the same time!

Male: I went to the bottle bank today, and guess what? It was completely full!

Female: Oh that's a shame. Did you have to bring all the glass home again?

Male: Yes. There was a sign saying not to leave anything on the ground . I really don't understand -why they can't empty it more often. What's the point of having a bottle bank if you can't put any bottles into it?

Female: You're right. Maybe you should write a letter.

Female: I think nuclear power stations are the best way to make energy because they don't make any pollution.

Male: That's not true. Just think about the waste they produce. Some of it is dangerous for thousands of years .

Female: There are safe ways to store it now- they can bury it deep under the ground.

Male: Well, I don't think that's safe - I would like to see more electricity being made from wind and the sun.

Male: Did you get that book about the environment I asked you to buy for me?

Female: Oh, sorry. I completely forgot. What's it called?

Male: How to Save the Planet. It costs £8 .99 and you can get it from Wetherby's bookshop.

Female: OK. I'll get it for you tomorrow when I go to town .

D1 Burning fossil fuelsto produce energy causes a lot of pollution.

Renewable sources of energy such as wind power, wave powerand solar powerare much cleaner. People can also easily reduce the amount of energy they use. A lot of electricity is wasted by leaving on lights, televisions and other electrical equipment when they are not being used.

Our society produces huge amounts of waste, which end up having to be burned, buried or taken out to sea. This waste produces greenhouse gasesand also spoils the environment. If we recyclematerial such as glass, paper and metal, this will reduce the amount

of waste that is produced.

D2 If more people used public transport, this would reduce the amount of

pollution. Public transport is much more environmentally-friendly,because buses and trains can carry large numbers of people at the same time, whereas cars often carry only one person. Car poolsare another way of reducing the number of cars on our roads . The big car companies are also working on developing new engine technology,

so that cars can run on cleanerfuels such as hydrogen instead of petrol. For shorter journeys cycling is a much healthier alternative to

driving a car, and many towns have introduced special cycle lanes.

D3 We can also help the environment by choosing to buy green

products, for example organicfoods that are produced without using pesticides. Not only pesticides are bad for the environment, the chemicals in them can also be harmful to humans. If we buy wood from sustainablesources, this will mean that our forests can be maintained for future generations.

So much of modern life is based around shopping and buying new things! Everything is out-of-date in only a few years or even months. If we stopped buying and throwing away so many things , this would help ease the pressure on the environment.
