Introducing wolves back into the ecosystem of Yellowstone not only stabilized the deer population but has had benefits to the entire biodiverse population of animals and plants and they are all thriving better.
Cutting down the population of whales did not increase the food supply of plankton and krill but reduced it so once again human tampering with the natural ecosystem did damage to it.
The lesson here should be obvious. Nature knows best and human alteration of it spells extinction for many species and throwing the ecosystem into an undesirable imbalance.
Human action should be focused on expanding the real estate of other natural national parks and reintroducing natural predators. Hunting should cease or be outlawed by humans where natural predators at the top of the food chain are reintroduced!!!!!!
