Depends on everyone You know that the conference "Rio+20" is being held now. The main theme of this sammit is protection of environment. I believe that everyone can help to keep the nature. I mean, even you aren't the member of Greanpeace you are able to do something simple in this direction: don't buy plastic packages and use textile bags instead of it; don't leave plastic utensil after picnic (plastic packages and utensil disintegrate in several decade!). And general: don't say: "I'don't care!" because the Earth is our aggregate home and it depends on each of us whether our planet will be beautiful or not.
