This is indeed a positive project!
Well, first it does kill two birds with one stone. It not only makes us care about our environment, it also have all people around the world (especially Twitter since we have a hashtag and tlist when we retweet) to have that checked and maybe couple of them will go and check out IGAB. It's like there'a an aim in an aim. ^^
Well, no matter what, Imma participate!
