Around the earth，there's a special kind of oxygen (O2) called "ozone (O3)"． But now air pollution is destroying it and has made a very big hole in the ozone layer (臭氧层).Too much harmful light from the sun passes through it and reaches the earth directly.This is very dangerous because it can cause cancer.
Carbon dioxide (CO2) in the air has increased a lot.It mainly comes from different kinds of burning materials.It has formed a "blanket (毛毯)" around the earth.The heat from the sun can't escape，so the temperature is rising. Therefore，this causes the level of the ocean to rise.
