There are several(prenominal) greenhouse gases respons! ible for warming, and humans emit them in a kind of ways. Most come from the combustion of fossil fuels in cars, factories and electrical energy production. The gas responsible for the most warming is carbon dioxide, besides called CO2. Other contributors include methane released from landfills and agriculture (especially from the digestive systems of grazing animals),...If you call for to get a full essay, score it on our website: OrderEssay.net
