I'll have to dig to find more letters from the Galapagos. I know there's an online Darwin correspondence project but there's something about books that I prefer. Maybe it's the feeling of moving forward you get as you page through and not the perfunctory skimming feeling of the internet.
So he's off to Tahiti where the natives are in harmony. I'm wondering if there has ever been a culture that hasn't transformed the land or over exploited the resources. Even in the Pacific islands, we know the natives killed off scores of endemic organisms. So it goes.
