Anyone ever wonder if its protection is for humans to enjoy it? since we love it so much, there is no chance we will ever let it die off. maybe thats the plan all along, to become so valuable to us we will continue to grow it (in massive quantities), and keep the species thriving. also, my thoughs of the plant self defense is that imo,the best chance is it's for insect protection (or possiblly heat, that also sounds likely).
