Nature Produces the Proper Size of Bone in order for animals to Survive
Look at the size of bone in deer.  It is not large. Their legs must take the stress of running and jumping to survive in the wild. There are millions of deer in the US with no leg crisis because they don't have large bone.	Here is the elk with no large bone in the legs. They carry a large amount of weight and have to survive in the wild. No crisis.
These are feral goats in Australia. They do not have large bone. These are wild goats that live in a semi-desert environment and must travel very long distances to find food and survive. There are approx 2.5 million feral goats in Australia and they are having a difficult time keeping the numbers down. No crisis.	Wild hogs travel many, many miles to find food and must be able to move quickly to survive. These hogs can easily reach weights of 300-600 lbs. Just in Northeast Texas, there are over a million wild hogs and the government can find no way to reduce the number of animals in the wild. No crisis.
