Cut down the greenhouse gases you produce. If there is anything that we do that affects everybody on the planet, it is the amount of greenhouse gases we produce. In the US, we produce more than any other nation. You can estimate the amount of carbon dioxide you produce by using the Carbon Calculator. However, for most of us the primary source of CO2 that we produce is from our cars. So drive less and if possible, get a more fuel efficient car.
