I saw this on PBS a few nights ago, and it's very interesting, I'm both awed and worried that carrot juice might be murder*, but it's very fascinating:
What Plants Talk About:
http://www.pbs.org/wnet/nature/episodes/what-plants-talk-about/video-full-episode/8243/When we think about plants, we don’t often associate a term like “behavior” with them, but experimental plant ecologist JC Cahill wants to change that. The University of Alberta professor maintains that plants do behave and lead anything but solitary and sedentary lives. What Plants Talk About teaches us all that plants are smarter and much more interactive than we thought! Buy the film. What Plants Talk About premiered April 3, 2013. (Video limited to US & Territories).
ETA: Unfortunately the video is only viewable within United States.
*I don't think I would ever be vegetarian even though I'm uncomfortable about eating animals, I can disassociate well enough by sticking to meat that is meal shaped instead of recognizably an adorable animal. Still, I'm hoping to /reduce/ the cattle meat in my diet by eating more vegetarian protein and considering entomophagy, I can't eat crickets or grasshoper because I imagine it'll feel like there'll be a cockroach in my mouth, ew, but I've eaten "larvets" I've brought from Tutti Fruitti just fine, I think I can eventually work up to a "mealworm casserole", but I need to figure out a way to kill those things, it's not like you can break their necks, I have a feeling they'll wiggle after they are dead(will they be dead if you behead them?). I would really like to be able to enjoy eating vegetables without remembering that part in the Nature program where the scientist says the grass are screaming in their own way when being cut because they were suffering trauma, what the hell?
Also, if god exist and was a fair god, things that looks cute and things that are delicious should be very different things.
