But do you know that many of the environmental problems our country faces today result from our fossil fuel dependence. Sample writingThe environment faces air pollution, global warming, acid rain, and several other very serious problems because of our use of fossil fuels has resulted in more than 25 percent increase in carbon dioxide in our atmosphere. Carbon dioxide is one of the main factors in global warming which is negatively affecting everyone.Fossil fuels also affect water pollution, land pollution, and thermal pollution (heat pollution). Coal mining is one of the causes of pollution in the environment. After the mining is completed, the land will remain barren. Materials other than coal are also brought to the surface in the coal mining process, and these are left as solid wastes.The production, transportation, and use of fossil fuels are to blame for the effects of pollution on the environment. Then what should we do? We should spare no effort to improve our environment. Please save energy and use fewer fossil fuels in our daily lives.Homework Finish your essay on the environment.
