I have absolutely no idea. But, listening to this 30 minute discussion on the legacy of Malthus was pretty interesting . From the blurb on the BBC's website: "Matthew Sweet hosts a dicussion about the eighteenth-century English Economist -Robert Thomas Malthus which explores why his theories on population growth are currently the subject of renewed debates" Locally, we also see these arguments playing out, with Advocates for a Sustainable Albemarle Population leading the charge. If you have any interest in this issue, on either side, listening to the BBC podcast will inform you on the global issues. I listened last night, otherwise I would have more details.
Striking down the mundane and dastardly while retaining a certain obscure turn of phrase, denoting something elusive yet concrete.
