I watched someone talk about this the other month. This actually isn't true at all.
Vegetables are in a perpetual state of war with the animals that eat them. Most vegetables are highly poisonous. For example, did you know that eating only 4 or 5 uncooked kidney beans can kill you?
Ineed to find the video but, they amount of damage vegetables do to us is kind of amazing.
I did not know that. Vegetable war could be a mechanism in some broader system, like the ecosystem. Don't ask me how, I'm an idea guy.
