Yes! Actually, Mexican farmers are still fighting to preserve their numerous (really numerous, really rich) variety of corn because capitalists and allies are pushing for monopolies (hence, the same seeds), for profitable crops (hence, the best seeds for that purpose), and rare seeds are in danger. It took centuries to get there...

Mexican ecological fights are bloody.

Personal rant. And I do not understand in which state of mind you need to be to kill someone protecting special corn seeds or butterflies. For what? More money that is not needed because there's enough already in the world? Go take it from the guys who retain it! Leave Nature, and their animals, and the people alone, FFS.
