2. What are the main ecological problems?
3. Why should the ecological problems be a universal concern?
4. What steps are taken to fight ecological problems?
4.Развитие навыков чтения текста с извлечением необходимой информации.
Let’s discuss the problem. You are to divide into 3 groups. You are given a text called Global Warming. Read it in groups for 4 minutes. You don’t have to translate the text but read it for gist. 
Раздать текст Global Warming. (Приложение 2)
Global Warming
    Global Warming is an increase in the earth’s temperature due to the use of fossil fuels and other industrial processes leading to a build-up of “greenhouse  gases” (carbon dioxide, methane, nitrous oxide) in the atmosphere. It has been known since 1896 that carbon dioxide helps stop the sun’s infrared radiation from escaping into space and thus functions to maintain the Earth’s relatively warm temperature (this is called the greenhouse effect). The question is whether the increasing levels of carbon dioxide in the atmosphere will lead to elevated global temperatures, which could result major climatic changes, and have serious problems for agricultural productivity.
    Since 1850 there has been a mean rise in global temperature of approximately 1°C(1.8ºF), but this rise could just be of natural fluctuation. Such fluctuations have been recorded for tens of thousands of years.
   The potential consequences of global warming are so great that many of the world’s top scientists have urged immediate action, and have called for international cooperation on the problem.
5. Let’s discuss the text:
What did the scientists discover in the 1980th? (They found out that the average temperature of the Earth's surface was slowly rising)
What are the causes of Global Warming? (people started using more and more energy in the form of fossil fuels, like oil, gas and coal)
What is let into the atmosphere while burning the fossil fuels? (carbon dioxide, greenhouse gases)
What kinds of natural disasters can be caused by global Warming? (Floods, droughts and damaging storms could be the result)
What are the possible solutions of the problem? (carpools, using public transport, saving energy, hybrid cars, using alternative energy)

6. Now turn your text paper and brainstorm your own ideas how to fight Global Warming using the ideas from text and your own experience. Fill in the table using the mind-map (ученики заполняют mind map, используя cluster-method – метод систематизации материала: ключевое слово – ассоциации – ассоциации ассоциирующиеся с ассоциациями) Work out 1 group idea – how to fight Global Warming? (Приложение 3)

as we can.
7. Read the text and choose the right option to complete the sentences.
Can we refreeze the Arctic?
This Scientist certainly thinks so.

    Thanks to global warming, the ice in the Arctic Ocean is today about half of  what it was in the 1980’s. And the situation can only get worse. Governments can’t agree about how to solve the problem. There is one scientist who is ready with a radical solution – to use modern technology to repair the damage.
    Harvard University’s Professor David Keith has published two papers on the subject. His idea is to inject reflective particles (ввести отражающие частицы) into areas close to the Arctic ice caps, so that less of the sun’s heat would be absorbed. So temperature will be lower and it will help some of the Arctic water to refreeze. The best part is, it could all be done without cutting back greenhouse gases created by people.
     Why aren’t governments all over the world working to give this new idea a try? Because this kind of open air experiments has never happened before. Nobody knows what the side effects will be. It could all work out fine or lead to something totally disastrous like collapsing (разрушение) the remaining ice sheets or worse, cause a massive drought (засуха). The United Nations Convention on Biological Diversity has a permanent ban (запрет) on any human attempt to try to change nature.
    Even Professor Keith agrees with that. That is why he is just presenting the idea in his research papers. Hopefully, we will be able to avoid these kinds of experimental solutions and stop global warming if we simply change the way we lead our day-to-day lives.
