The GHE(greenhouse effect)is: In the atmosphere are gases like Carbon Dioxide, Methane and Nitrous Oxide. They are bad if they are in excess. These gases form a layer and keep the Earth warm. The sun rays fall on Earth and some heat returns to space. But a part is absorbed. The greenhouse gases are good because they regulate the temperature.	If these gases´s layer grows, the temperature will rise a lot. There are things that contribute to the increase of these gases : in one side smoke from the vehicles and the factories. In the other side people is cutting down trees and forests are disappearing.
The Ozone Layer is a layer around the Earth that protects us from the damage caused by UV rays. They cause Skin Cancer, Eye Cataract, Sunburn and less plants. Humans are destroying the Ozone Layer by using things that have a gas called CFC.
