Try saying this to an environmentalist. Just make sure there's space in the room for the newborn cow.
"Old growth forests" are the holy of holies for the environmentalists and their Gaia-worship.
I think old growth forests are good for some wildlife. But nature doesn't allow for eternal forests. The trees eventually burn, rot or petrify.
Here in the northeast, woodpeckers have been increasing in number. That's been attributed to what they are calling the 'second growth' of cleared farmlands now returning to nature. Those second growth trees are becoming the older trees needed by woodpeckers.
The Gaia worshippers are nuts but not always entirely wrong.
