I think that plants, especially trees and flowers, are not so "dumb"
as they seem.These beings are much more intelligent and may
communicate in a way we don´t understand.They may form a network where
a single tree is just a "neuron" in a giant "plant-brain".

I think trees and flowers and gras are fighting humans, that destroy
the forests and pollute the water.

Plants can attract humans by smells, so that they crash their cars
against trees - looks like an accident, but was murder by a tree.
Sea-plants can attack ships and sink them, nobody will survive to
tell.

Plants can produce drugs and psychotic substances that turn humans
into terrorists or madmen like Adolf Hitler.Plants are at war with
humans and manipulate humans for war, so that humans kill each other.

This is true, scientists who try to examine this will be manipulated
by the plants, so that they can´t tell the public that plants are evil
and dangerous.
