Why can’t all these PhDs understand that growth can never drastically outpace resources? The less resources around the lower the fertility rate? If you look at any animal population in a given area it never outpaces its resources.
That is NOT true. Check any pond with bluegill and / or green sunfish and a lack of enough predators (fishermen, bass, large channel catfish, etc...) The bluegill and / or greenies will explode in numbers, but will be stunted and usually are in in poor body condition. This situation will continue until something drastic is done to reduce their numbers: Often the solution is to kill all the fish in the pond and start over (cheaper & faster than stocking large predators). Something similar happens with deer & lack of predation in some areas: You wind up with large populations of animals in generally sub-par condition.
