I answered once already. Do I need to repeat it.
There is no "natural" balance.
We changed all of that, so a new balance is needed to best serve the interests of all people.
It is you that needs to think before you post. The natural balance today is based on todays conditions, not the conditions that existed 200 years ago.
The quality of the habitat determines the natural balance and some areas may only be able to support 20 DPSM while other areas may be able to carry 40 DPSM.
