Here are the causes of global warming:
Ozone Layer
Hole in Ozone layer is the first causes of global warming. Ozone layer is 16 Km high from the earth for protecting bad rays of the sun. And this ray is getting damaged day by day. Ozone layer gets damage by paint and pollution.
We are doing pollution a lot and resultant is the hole in Ozone layer. Because of ozone layer, temperature of earth gets in control. However, when we got the hole in ozone layer then temperature is not in control now. It is increasing day by day, and it is the first and foremost reason of global warming.
Uncontrolled Cutting of Trees
Cutting of trees is another reason of global warming. Trees attract clouds to rain in earth and make lower the temperature. People are cutting trees without any permission of nature. They are playing with nature and this will be resultant of global warming. Therefore save trees and cutting of trees.
Pollution
Pollution is the biggest reason of global warming. People are polluting the environment day by day. Pollution is the root cause of warming the earth. When environment will be warm then trees and earth will get adverse effect, then they will consume heat and release heat in the form of global warming.
