Giving pure water to those in need

Ok, so I know that giving pure clean water doesn't help the enviroment directly, but this is still a important post. I have found a website that tests your geography skills by showing you a map of the world, and asking you to click on specific locations like "Mount Fujii in Japan" then, however close you are to the target, they will reward up to ten cups of clean water to kids in poor countries. Here is a link to the website: freepoverty and I won 124 cups of clean water in one single game of 5 minutes. Good luck and keep greening!
