Good question about the pesticide... I would think that there is something morally wrong with using a poison if something has intelligence to be aware of it. Though, I can already find holes in the statement I just made.
Well I guess a better question would have been herbicides... since pesticides only help the plants, lol. Pesticides would be to plants like what a vaccine is to us. Herbicides would be mass genocide.
I actually did that on one of my Plant Biology exams. I put pesticide.... and then when I went back to double check, I was like wtf was I thinking?! Herbicides are used on plants! Not pesticides! Almost lost some points there...
on mythbusters they sent electrical impulses thorugh plants to see if they reacte in a way that would show a brain telling the body of pain. it happened for a plant but not for anything else like yogurt, which is alive.
