Enviromental problems

The Earth is a home to millions of different kinds of living creatures, which are linked in many ways. Together, they make up the complex world of nature. But there are different types of eco-probles, that harm them:

• Greenhouse effect. It works like this; sunlight gives us heat. Some of the heat warms the atmosphere, and some of the heat back into space. Nowadays the air surrounding the earth has become much warmer because the heat can't go back into space. That's why winter and summer temperatures in many places have become higher.

• World temperatures are currently rising every year. This so called global warming is caused by the buildup of gases and water vapour in the atmosphere. These gases form a layer that reflects the heat back to Earth, rather than allowing it to escape into the outer atmosphere. As the planet warms up, the water in the oceans will take up more space and water locked up in glaciers and the polar ice caps will start to melt. This could cause sea levels to rise and many habitats will disappear under water.  

• Acid rain fall when poisonous gases from power stations and vehicle exhausts mix with oxygen and moisture in the air. Acid rain poisons or kills wildlife in lakes, rivers, and forests, and damages the surrounding plant life.

There are the main problems. So I must say , that we should do all to save our World.
