The main reason for climate change is global warming, acid deposition and ozone depletion. And environmental pollution is the main cause of these things.

Among these three points, I choose Global Warming.

There are two reasons for the global warming, one is caused by the natural earth atmosphere system, the other is caused by human pollution. I'm going to focus on human pollution.

There are many solutions to these problems. Humans should not cut down forests and turn them into fields, nor should they burn forests. This method can reduce CO2 and thus mitigate the greenhouse effect, and also solve the problem of soil erosion. In terms of transportation, people should advocate green travel, use more bicycles or public transportation equipment, and reduce the number of using private cars. This reduces the amount of gas emitted by cars. In industry, people should reduce the emission of some harmful gases or fuels that cause the destruction of the ozone layer.
