I'm pretty sure plants aren't animals.
Animals don't need the help of plants when there are so many insects around to decompose us in our sleep.
Plants can be pretty freaky though
We...do have other food...and they have to eat as well, so it's a disadvantage for them too. And we eat what we kill, and we'll be doing a fuck of a lot of killing.
A lot of the pro-human arguments seem to assume that every Joe-public has easy access to effective weaponry and specially-designed shelters. This is a nonsense...
And the idea that all the animals of the world could unify themselves and communicate with each other isn't? If the animal side in the retarded debate is allowed to use complete fantasy, so should the humnan (correct) side.
But seriously, is your interpretation of the scenario any different than the way animals behave right now? If there's no big difference, then clearly we'll win. We've already colonised nearly every inhabitable piece of land in the world, destroying countless animal habitats along the way. You seem to be downplaying the intensity of these hypothetical animal attacks for your convenience.
