One of the great joys of camping out in a national park is chowing down by the fire. But campers aren’t the only ones drawn to burgers and s’mores roasting over an open flame, beneath a mass of twinkling stars.
Those rich aromas can also prove irresistible to the local critters. From bears to foxes to coyotes, biologists have documented wildlife getting irrevocably hooked on our food and food waste. And for good reason: Our food is way more calorie-rich — and thus, better for making babies — than the standard black bear fare of insects and leaves.
