Read and speak on the reasons of the greenhouse effect. Now scientists are more or less sure about the greenhouse effect, which makes the Earth warmer by trapping energy in the atmosphere because certain gases (carbon dioxide' methane and some others) prevent heat from escaping into space. Look at the picture and say how people increase the amount of such gases in the atmosphere. Add some more examples to illustrate your answer.
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 i 200 years ago, the need for energy has steadily increased, I 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?
a) Read five short conversations on pages 147-148. For each one choose si a word from the box to describe the speaker's main purpose.
1 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?
2 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!
3 Ma/e: 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? Ma/e: 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.
'We'll
4 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. 5 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.

Читать и говорить о причинах парникового эффекта. Теперь ученые являются более или менее уверены о парниковый эффект, который делает земля теплее треппинга энергии в атмосфере, потому что некоторые газы (диоксид углерода ' метана и некоторые другие) предотвратить тепла от побега в космос. Посмотрите на картинку и сказать, как люди увеличить количество таких газов в атмосфере. Добавьте еще несколько примеров для иллюстрации вашего ответа. Спросить и ответить на вопросы в парах. 1 Почему люди в начале нового тысячелетия тратим столько времени и усилий, привлечение внимания общественности к проблеме экологии? 2. какие экологические проблемы, которые в настоящее время сталкивается человечество, по вашему мнению наиболее актуальны? 3 Почему являются ученые настолько обеспокоены парниковый эффект и процессом глобального потепления? 4 как вы думаете, что глобальное потепление вызвано деятельностью человека? Какие из них? 5 после промышленной революции, которая началась более чем 200 лет назад, возрастала потребность в энергии, я не так? Почему люди в настоящее время весьма обеспокоен энергии они используют, чтобы свет и тепло дома, энергии, что делает автомобили работать, и т.д.? 6 это известный факт, что в ходе истории земли были периоды резкого климата изменения, которые произошли естественно, ледникового периода, среди них. Почему вы думаете, что ученые настолько обеспокоены текущие изменения климата? 7 можно сказать, что изменения климата в том месте, где вы живете? Каким образом? Вы найдете эти изменения к лучшему или к худшему? Можете ли вы привести примеры изменения климата в других местах планеты? 8 вы думаете человечество может решить экологические проблемы в мире?
