Our world is in danger. We must do something to protect the environment. But, what are the main problems we face?

The greenhouse effect

The atmosphere around the Earth is necessary for all living things. It is like the glass of a greenhouse, letting sunlight in and keeping heat from getting out. Without it, the Earth would be the same as the Moon-cold and lifeless.

When we burn fuels such as petrol and coal, we produce a gas called carbon dioxide (CO) Too much of this gas pollutes the atmosphere, and gets it to keep in too much heat. As a result of the greenhouse effect, the Earth's temperature is increasing. This led to sea level to rise, and in the future may make cities disappear.

Cutting down forests

Every year, we destroy nature by cutting down huge areas of forests. This makes greenhouse effect worse because trees take in CO and produce oxygen. Cutting down trees also destroys the homes of the animals that live in our forests, and makes the surface of the soil be easily destroyed by rain. This can result in floods and even more damage to the environment.

Bad habits

Many of our habits result in pollution. People often use things once and then throw them away. This creates mountains of rubbish and pollutes our land and seas.
