It's actually hilarious how many plants we cultivate specifically for their defense mechanismsAlliums: We have nasty sulfur compounds that turn into literal tear gas when our cell walls are broken! No animals are getting at our sugar stores!Humans: Mmm tasty sulfur compounds, I'm gonna eat you with everythingTea and coffee: Haha, bugs die when they try to eat us because we grow our own pesticide!Humans: Ugh don't talk to me until I've had my pesticideAll manner of herbs and spices: Nice try, critters! But we are filled with volatile oils that are dangerous and offputting!Humans: Ooo this one is good with my pesticides, this one tastes great with the sulfur compounds, this one makes amazing desserts, oh my god yes.Spicy peppers: Fucking mammals grinding up our seeds in their gross molars! No more! Only birds can tolerate our heat!Humans: I'm gonna dry you up, grind you into a powder, and use you as a staple seasoning for entire continents' worth of cuisine
