We're the ones who can make a difference. If we lead lives where we consciously leave the lightest possible ecological footprints, if we buy the things that are ethical for us to buy and don't buy the things that are not, we can change the world overnight.

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.

To me, trees are living beings and they have their own sort of personalities.
