I know I've been all over Mongabay lately, but there's just so much good stuff there. First on the list is a longish article about a study in Biotropica, which suggests that instead of losing up to seventy-five percent of our biodiversity as many scientists fear, we may only lose twenty, maybe thirty percent tops. However, there are no guarantees that come with the study. The optimistic figures, if you can call them that, are largely the result of declining rural populations and the subsistence farming that goes with it. In short, saving much of our biodiversity hinges on continued urbanization. Grab a beer and go read it.
