On the documentary he explains there was no sense in those days that fauna were a limited resource.

That private following partly explains why such a limited resource should command a market capitalisation of just short of 1.8 billion.

Competition can occur when two or more species share a limited resource, such as particular food sources, in a given area.

This leads to conflict with sports and commercial hunters and fishers, who are competing for the same limited resource in the same place.

This pattern results from evolutionary change driven by competition among species for a limited resource (e.g. food).
