“The beetles, they’re native, and they’ve kind of been evolving together with the trees over time,” he said. “So in outbreaks, the beetles kill most of the trees, but a few survive. Nobody’s actually sure which trees are reproducing on the landscape, but the trees do evolve over time.”

I am absolutely fine with allowing the timber companies to spray _some_ pesticides on the vast acreage that they own.

I am _not_ at all fine with spraying toxins that have been banned in multiple countries, are toxic to our endangered animals, poison our water supplies, and simply generate higher profit for the timber industry — in our designated Wilderness areas. Not. Their. Land.
