" Clear-cutting" was the word for what the Rusties had done to the old forests: felling every tree, killing every living thing, turning entire countries into grazing land. Whole rain forests had been consumed, reduced from millions of interlocking species to a bunch of cows eating grass, a vast web of life traded for cheap hamburgers.
"Look, we're not clear-cutting. All we're doing is pulling out the garbage that the Rusties left behend," David said. "It just takes a little surgery to do it. "
