Solutions in progress (click on this--it's a video don't worry)

So, I know that I have been posting a lot of Global warming stuff, but this problem is imminant and something I'm really passionate about. Global warming isn't a far-off issue that we'll get done tommarow. We have to start soon, now even. So if you know how to do it, maybe you'll be interested in making a difference. (forgive me for sounding a little cliche`)
In each of these videos (I'm including the one at the bottom) people are finding ways to save money and help the environment--which, duh, helps us and the whole world. Just take the time to watch the vidoes, both of them only total less than ten minutes.
