Here's a scary fact: the damage we're doing to our planet might literally bite us in the butt! As global warming increases, so does the Leishmaniasis bacteria, a form of flesh-eating disease. The potentially fatal illness is spread by tropical sand flies, and as our planet heats up, the ideal breeding grounds for these critters increases. It's already beginning to migrate to northern Europe, and unless the climate change crisis is brought under control, nothing will stop these guys. Through human ignorance, we are literally causing our own destruction.
