Sloths risk their lives every time they poop. It’s basically the only reason they descend to the ground, even though over half of them die whenever they leave the safety of their trees. They can get pretty backed up because it only happens once a week – so every time a sloth poops, it has to stand up, hug the base of a tree, and do a little poo dance to get it all out.
