Planetary Responsibiliy We can be evil, as long as we moderate ourselves, enough to allow for good.
If we're not to fall into temptation of meat, per se, then meat trees or some other alternative ought to exist. They don't, people will kill animals, and as long as they don't over consume, it's ok.
Yes, we are a part of the planet, but still, if we weren't so evil, the planet would be self-sufficent (including humans).
The planet doesn't need help, it implies we work for the planet's health, rather than just live - we need to moderate ourselves.
Edit: Okay, maybe I'm wrong, we have been very evil. It may need help, but that's an abnormality.
