I'm not arguing against old growth, in fact my son and I make it a point to hike in as many designated Wilderness areas as we can. But the religious fervor to save trees is actually screwing up theses areas. We took a trip to a Wilderness area in Oregon in 2003. It was surrounded by national Forest, and the environmentalists had prevented the harvesting of trees throughout this whole area. Throughout the Forest there were stands of trees that hadn't been harvested in decades, along with tons of highly flammable forest litter that accumulates when trees are left basically unmanaged. The whole fucking place burned down two weeks after we visited.
You do know the difference between Wilderness and Forest, don't you?
My point is that if the environmentalists would go away, the Forests would be harvested as they need to be, and the Wilderness areas could them survive.
The same thing about the Amazon areas. If the folks who lived there had a market for the exotic wood, they'd manage the areas as Forests instead of trying to assume some European farming economy. And a healthy Forest includes Wilderness areas to preserve the native ecosystems.
