environmental problem

I feel that the earth is endangered now. For example, Global warming, acid rain, and
 Depletion of ozone layer. These are all things caused by people. When the envirommental destruction. We are on the verge of the edge of extinction. Is there a method of evading this crisis.

I think that there is a solution. Out the countries in the world is necessary to solve the problem. First world should generate electricity by the nature power. For example, Photovoltaic generation, Wind power generation, Hydraulic power generation, etc… 
Second All cars are changed in to the electric vehicle. Third it is necessary to decrease carbon-dioxide emissions of the factory. Finally you should plant a plant in desert. I think that the global environment improves if these can be achieved.
