Although Mario's diet consists almost entirely of raw foods, he doesn't consider himself a hipster. And he doesn't really care about the environment, no matter what he tells Princess Peach about his recycling habits. He's always throwing banana peels on the ground, and he's probably brought a few species of reptiles significantly closer to extinction.
