Stuart McMillen’s comic “St. Matthew Island” is a parable about population control, resource scarcity, sustainability, and biodiversity, with bonus cute reindeer.
Here’s the short version: The reindeer of this tiny Bering Strait island weren’t native, but were brought in by the U.S. military. Left to their own devices, they thrived, then competed for dwindling resources, then … well, you can guess the rest of the story, but it’s well worth reading the whole thing.
