Four Laws of Ecology

1. Everything is connected to everything else: One ecosphere for all
2. Everything must go somewhere: Nature has no waste bin
3. Nature knows best: technological improvement is likely detrimental for the system
4. There is no such thing as a free lunch: exploitation transforms useful to useless
