Слайд 2

About 150 years ago the air was pure and clean.

Слайд 3

Then people started building factories and many of the things they make, like cars, put a lot of harmful gases into the air.

Слайд 4

Today the air is so polluted in some places that it’s not always safe to breathe there.

Слайд 5

Many cities around the world have air polluted with “smog”. This is so strong in some places that the air, which should be a beautiful blue, looks brown.

Слайд 6

The planet Earth is mostly water. Oceans cover the biggest part of it – and there are lakes, rivers, streams and even water underground. All life on the Earth – from the smallest bug to the biggest whale – depends on the water. It’s precious.

Слайд 7

But we are not doing a very good job of keeping water clean. In many places, the water has become polluted.

Слайд 8

Rivers and lakes are polluted by garbage or by poisonous chemicals which are dumped right into them.

Слайд 9

Underground water can be polluted by gasoline or by harmful liquids that seep into the ground. Some fertilizers and pesticides used in farming leak down through the dirt, too.

Слайд 10

When you throw something away, it goes in a garbage can.

Слайд 11

Once a week a garbage truck comes and the can is emptied, and that’s the last you see of it. But what do you think happens to the garbage then? Does it just disappear? No way!

Слайд 12

Now we are making so much garbage that in many places, there is not enough room to bury it all.
