How the Sloths Age

In the Amazon Rain forest many things have changed over the years. Not just the environment but also the Rain forest wildlife. How have all of that changed you may ask? I think the forest and animals can change in many different ways. Like they could get smaller or bigger or they could lose hair or even grow more. The environment can change in many ways too like there could be more trees or there could be more water streams. For my animal I chose a sloth which can be found in many different rain forests, not just the Amazon. I think sloths would get smaller and get a different pattern and I think the environment would have less trees and more water streams.
