Global warming is caused by human activities that release greenhouse gases into the atmosphere from sources like burning fossil fuels. Some key greenhouse gases are carbon dioxide, methane, and nitrous oxide, which are emitted through processes like breathing, farming, and industry. While all humans contribute somewhat, developed nations like America produce far more greenhouse gases and are largely at fault for global warming. Reducing electricity use, recycling, and choosing active transportation can help avoid worsening the effects of climate change.
