Clear-cutting old-growth forests—yes, that's terrible and should never happen. But clear-cutting forests that were planted specifically to be harvested? That's fine, good even.
In the time it takes a forest to grow it will be home to many species which we utterly fuck up when harvesting the forest, once again putting one more nail in the coffin of our own food supply.
The forest tending of Scandinavia is a good example. The "plantations" are not entirely monoculture and can never be in fact. Healthy forests are anything but only trees, there are so many other species required for a healthy forest.
