Task 1. Read the text and answer the questions.
Climate changes.
Climate is a weather a certain place has over a
long period of time. Climate has a very
important influence on plants, animals and
humans and is die. Scientists think that the
reason is greenhouse effect. It is caused by
carbon dioxide (углекислый газ). Carbon
dioxide is produced when we burn things. Also
people and animals breathe in oxygen and
breathe out carbon dioxide. As you know, trees
take this gas from air and produce oxygen. But
in the last few years people have cut down and
burn big areas of rainforest. This means that
there are fewer trees and more carbon dioxide.
This gas in the atmosphere works like glass in a
greenhouse. It lets heat get in, but it doesn’t let
much heat get out. So the atmosphere becomes
warmer.
Greenhouse effect is sometimes called global
warming.
Questions for own answers:
1. What can you say about global warming?
2. What our scientists are doing to save our
planet
3. What are the main ecological problems?
4. Is there any way to make our air cleaner?
5. Why are forests important for life on the
Earth?
