The world is moving toward cities. According to Brand, we passed a threshold recently. Now most of the world is urban, and is rapidly becoming more so.
Watch the video. He makes some real interesting points about the one billion people living in slum cities. Rather than seeing them as hopelessly poor, Brand sees them as entrepreneurs who are fighting their way out of the extreme poverty of subsistence farming.
His short talk ties together the issues of green living and poverty in a way that is quite helpful. When resources are scarce, wars break out. For example in Darfur, much of the fighting is created by a struggle over who will control the less than adequate water supply.
Very interesting stuff.
