well, my feeling is, and it's really the same message that you get from most greens and most environment books, is that under-consumption, that is poverty in the poor countries, is linked to over-consumption in the rich countries, and we have to grasp this nettle — it's one that the conservative party in its white paper on the environment avoids noticeably — we have to grasp the nettle, that as long as we are over-consuming there's not going to be enough to go round everywhere, and my book shows that this pattern is really a three hundred year old pattern dating from the first colonial expansion of europe and the slave trade, and it's still going on today.
