Don't be so complacent about the green plants.
There are a huge number of deadly plants.
Not only do most of the really deadly ones look just like the edible ones, but a lot of them will kill you if you just walk too close to them.
People have been killed by sleeping under some of the poison dripping trees.

It is very unwise to go near anything green. Green things kill.
