Plants have a kind of intelligence that operates at a slow timescale, so that humans usually don't notice except through careful study.

Occasionally people do notice. There is a kind of tea from Taiwan which is made only from leaves that an insect has started to chew on, because those leaves taste different.

Although plants make complex decisions, no evidence has been presented that any plant engages in conscious thought. Without conscious thought, I don't think an organism is entitled to the right to life.

Isn't it silly how people find it hard to call it a crime to wipe out a species unless the individual members of it have rights? Wiping out a species is a wrong of a different kind, a crime against the world, regardless of whether the individuals of that species have rights as individuals.
