The combustion of fossil fuels is one of the biggest sources of carbon dioxide emission in the atmosphere, and carbon dioxide is one of the greenhouse gases resulting in global warming.
Use of fertilizers and pesticides: The application of fertilizers and pesticides pollutes the soil that is fertile, due to the presence of toxic constituents in them.
