It’s a wonderful world we live in.
For thousands of years the Earth has given support to all forms of life – human beings, animals, birds, fishes, insects and plants.
But now many species of animals and birds have disappeared.
Millions of animals die every year because a man has polluted their natural homes. Besides, every year people cut down more trees, build more roads, and use more land for farming.
This leaves fewer jungles, fields and forests for wildlife.
The country air, once clear and fresh, now may be polluted by power stations and factories.
Go to the seaside and you’ll see the pollution around you.
There is a lot of litter on the beaches.
We live among litter and wastes which we have created ourselves – fumes of cars, throwaway packaging, etc.
These are some of the world’s most serious environmental problems.
And it’s no good pretending they don’t exist – they do.
What’s more, they are getting worse all the time.
