A way to help lower carbon footprints is to do everything you can to try to lower it. Every little detail you take to lower your carbon footprint is useful because eventually if everybody chips in a little it can lower our total carbon footprint drastically. Stuff like taking a shorter shower or not using the lights when there is light outside will lower your carbon emissions slightly, but will make a bigger impact later on. Different regions also can lower their carbon footprint in different areas. Some nations may have higher transportation footprint numbers, but a different nation may need to conserve around the home.
