Pneumonia in bighorn sheep halts hunting near Yellowstone

People fight for them because they're a native species. Fine. But like Australia, whats 'native' no longer applies since humans have spread a bazillion new species around...

I've always felt this way too. Humans aren't the only ones that spread species around either... nature has always done this herself in one way or another. What exactly qualifies as "native" and what makes "native" better than the plants and animals that were introduced and are now thriving? Is nature no longer allowed to evolve? I understand the foolishness and immorality of wantonly wiping out native species just to suit human needs, and I certainly advocate the idea of doing our best to preserve the wild species that were here before us. Yet there is also a time when you have to recognize that some species are not going to make it on their own even if you give them every opportunity. The world changes, and plants, animals, and even humans must adapt or eventually become extinct.
