Many ecosystems have been already reduced to: grass, goat, pig, sheep, cow, person, dog, cat Currently we catch wild fish to eat. That will cease some day (we'll run out) & we will grow most of our fish in farms. So.... these are probably the last 100 years of wildlife. Unless people make drastic changes.
