If you click on the above image it will take you to a site in which they ask you to make a small change in your life. The small change will reduce your impact on the climate change (i.e. global warming). This months pledge is to wash clothes in cold water instead of hot water, this simple change will use less energy and therefor cause less of an impact on the environment as well as cost you less money (because your not paying to heat the water unnecessarily). While the pledge is only for the United States you can still cut back on the amount of hot water you use even if you don't live in the US.
