Unit 9. Exercise 16. Read and listen to the text.

Save the world.

Hello, Dad. What are you doing?

I am watching a documentary about global warming.

Global warming? What is it, Dad?

People cut down trees and factories and cars emit harmful gases into the atmosphere.

So the amount of oxygen on Earth is decreasing.

The Earth is getting hotter. Scientists call it the greenhouse effect.

This causes global warming.

Is it dangerous?

What happens if the Earth gets hotter?

Of course it is very dangerous.

Glaciers melt and sea levels rise.

So many animal species can survive and they die.

It affects the balance of nature.

Global warming threatens humans too.

Oh, I see. But we are superheroes, Dad. We can save the world and the people.

I am sorry, son. We can't do anything.

People are responsible for it and they should become aware of all these environmental problems and take action.

What should people do to prevent global warming?

They must protect the energy sources and they mustn't waste them.

They mustn't destroy forests.

They must plant more trees.

They should use public transportation to reduce air pollution.

They mustn't throw litter into seas.

They must use eco -friendly products.

They shouldn't use fossil fuels.

They should use renewable energy like solar or wind energy.

You're right, Dad.

When I go to school, I will ask my friends to make a campaign for global warming.

It's a good idea. Well done, son.
