We need to think wisely: as a society People don't realize that every individual decision they take has an impact in a social and in a historical level. If someone eats a snack and throws the envolture in the street, he or she might not realize what's the impact of that little action, because he/she doesn't see anything big and bad happening at the moment; you know, the envolture doesn't get on fire, or starts an earthquake, or something cathastrofic, it just stays there and then in some hours it moves to somewhere else. But a lot of this insignifficant actions has caused so many problems to our planet in a big level, so that we actually have climate problems at the earth. The person who throws a little envolture at the street is now part of a historical and colective negative force that is changing the natural way the earth worked for many years. That little action is part of a cathastrofic force, so big and so bad that modifies something that seemed to be unmodifiable.
