It's important because there is a cycle ad if the sloths are not protected they will keep on decreasing and that "food chain" will start to break. For example, if the number of sloths decreased the animal that ate them which is the jaguar will ALSO decrease because they don't have the sloths to eat anymore, and the animals that the sloth eats will start to increase so much that it will find a way to harm the environment. So we should protect sloths because if their population decreases the "food chain" will get all jumbled up and it will harm the environment.
I hope this helps!!!!
