Of all animals on earth you chose the only one that earns money to pay for its food and water. As well as the only one that can not survive birth in any environment on earth. While a polar bear, fish or deer is perfectly suited for it's environment the frail human is not. It whether in Roman times or during the Qin Dynasty required clothing, education and protection from the environment it was born in.

While a bird is born knowing how to build a nest this human creature most often will fail to do the most basic things that is in it's own best interest.
