The Four Laws of Ecology
Formulated by physicist and ecologist, Barry Commoner.

1) Everything is connected to everything else - humans and other species are connected/dependant on a number of other species.

2) Everything must go somewhere - no matter what you do, and no matter what you use, it has to go somewhere. For example, when you burn wood, it doesn't disappear, it turns into smoke which rises into the air, and ash, which falls back down to the earth.

3) Nature knows best - Like it says, nature knows best. As much as you think it might help a place by repainting it, you are submitting the fumes into the air and into your lungs. Why not put siding on it?

4) There is no such thing as a free lunch - Everything you do, must have a reson behind it. For example, a class pizza party. In order to win the party, you have to fill out a survey, and submit it back to your teacher. This law basically means you have to do something in order to get something in return.
