Sloth's Transformation

Currently, the sloths only eat twigs, leaves, and plants and have only molars. In the future I think that they will need to grow incisors and canines to eat meat. The reason why I think this is because there will be less leaves, twigs, and plants so they will need to eat meat in order to survive. The future sloth will need to be an omnivore. The future sloth will still eat some leaves, plants, and twigs, but they will also eat other animals. That is why I think sloths will need to grow incisors and canines.
