Trees, Fish, and Meat

I know for the most part we need foresters, deposits ect to refill the trees, fish and meat on our island but should some natural renewal occur in the game. I know that in nature stuff comes back and new trees grow and fish and stuff you hunt mates and you have new ones. This may be a stupid idea but I would like to see some natural replenishment.

No cause that would take away the natural feel of throwing bread into water to make fish...dont you understand!
