Wars not only harm the ones involved, but they harm the Earth in a much more drastic way. During the war with Iraq in 2008, we used as much oil as over a million car do in a year. The Earth has a limited supply of natural resources, and the more wars we have the more we deplete these sources. The vehicles we use in wars consume massive amounts of oil, and release carbon dioxide which adds to the greenhouse gases in the atmosphere. This in turn will lead to global warming that then affects the environment in a negative way. In the end the environment is what suffers from what humans do on a day to day basis.
