Nowadays, there are several serious environmental problems, some of  which bring the disadvantages even the natural hazards to us, so have you ever thought how to prevent it or whether we need to take the influence of the environmental destruction into consideration?

   One of these problems is the air pollution. As we all know, when people go outside, they usually drive a car and emit the waste gas .The gas contains much carbon dioxide which is the main cause of the global warming. The global warming brings about the sea level to rise so that a great number of cities would be submerged.

   In order to pursue the economy profits, another severe problem is deforestation. It is widely acknowledged that extensive deforestation would lead to flooding. In addition, a heavily forested area, such as Southern Australia always has wildfires because of its drought ,arson and global warming.

   In conclusion, to lessen the negative impact on our earth  relies on our citizens. For instance we should take the public transportation as much as possible, moreover we could also prevent the over-exploitation so as to reduce the natural disaster.
