    Cutting down trees, driving cars, burning coal, and using air conditioners are all means in which people increase greenhouse gases in the atmosphere. Cutting down trees increases greenhouse gases because trees remove carbon dioxide from the atmosphere for photosynthesis and release oxygen in return. Burning gasoline in cars emits carbon dioxide, as well as using air conditioners, which need energy (by burning of coal or other fuels) to function. Burning coal releases not only carbon dioxide, but also nitrogen oxide, another greenhouse gas. In addition, burning coal distributes sulphur dioxide into the atmosphere (which forms acid rain), aresenic, lead, mercury, hydrocarbons, and other harmful substances.
