Last but not least, we have the most benign bane of park ranger’s existence: Littering. One park ranger watched a man dig into two McDonald’s cheeseburgers with an order of fries and a large drink, and then leave his greasy garbage strewn on the floor of a national forest. Littering is less likely to get you killed on vacation than trying to bring home a baby alligator, but the consequences are severe long term.
Wildlife becomes habituated to humans, losing their natural fear of us and learning to rely on campgrounds, farms and human settlements for food. In addition to disrupting the food chain, this dramatically raises the odds of dangerous encounters between large wildlife, particularly bears, and people. Most of the time, these encounters result in the necessary euthanization of the animal. Not cool.
