Save our planet

The ozone layer is a very important part of our atmosphere. The ozone layer stops some of

the ultraviolet radiation from the sun. Ultraviolet radiation causes a suntan. Too much

ultraviolet radiation causes sunburn and skin cancer. CFCs in the atmosphere have caused a

hole in the ozone layer. Scientists first discovered the hole in 1982, and it is getting bigger.

Thirty per cent of CFCs come from aerosol cans, thirty per cent from fridges and air

conditioning, and thirtyfour per cent from the production of some plastic products.

Sunlight gives us heat. Some of the heat warms the atmosphere, and some of the heat

escapes back into space. During the last 100 years we have produced a huge amount of

carbon dioxide. The carbon dioxide in the atmosphere works like the glass in a greenhouse.

It allows heat to get in, but it doesn't allow much heat to get out. So the atmosphere becomes

warmer because less heat can escape.

Where does the carbon dioxide come from? People and animals breathe in oxygen, and

breathe out carbon dioxide. Trees take carbon dioxide from the air, and produce oxygen. We

produce carbon dioxide when we burn coal, oil, petrol, gas, or wood. In the last few years,

people have burned huge areas of rain forest. This means there are fewer trees, and, of

course, more carbon dioxide!

Some scientists think the greenhouse effect will make the world hotter. Areas near the coasts

will be cloudier and wetter. There will be more storms. Inland areas will have a little more

rain, but because the temperature will be higher, they will be drier. Sea levels will rise. They

have already risen by 15 cm since 1880. Maybe they will rise another 30 cm before 2030.

But clouds reflect sunlight back into space, and maybe more clouds will make the earth

cooler again. Is the world's climate changing? We don't know.

5. When we burn petrol, coal or gas we produce oxygen.

6. Airconditioning does not damage the ozone layer.

7. Acid rain is rain that contains dangerous chemicals.

8. Trees produce carbon dioxide.

9. Global warming is caused by the hole in the ozone layer.
