Impact of society on environment

Many Societies make impact the environment example in some cities have a factory that produces a product to make money for this cities some of it use fossil fuels to burn or melt some material so it makes pollution to the air. It released many kinds of gas some of it are compound of the acid rain like sulfur dioxide and nitrogen dioxide. It's mix and reacts with water, oxygen, and other chemicals to form more acidic pollutants this make acid rain. Acid rain destroys tree and buildings.
