Maude Barlow is a Canadian activist and author who travels the world telling a simple and compelling truth: we are running out of water. And with that, comes devastating consequences. The author of Blue Covenant: The Global Water Crisis and the Coming Battle for the Right of Water explains the phenomena of “hot stains”, where large areas of the earth’s surface are running out of clean, drinkable water and describes this as “the most important ecological and human threat of our time.” Barlow is informed and passionate and gives a frank assessment of the state of water in Australia. “You have a right to be really angry with your governments,” she says. “What we’re looking at here are years and years of mismanagement, collusion with corporate and special interest organisations and industries, ignoring scientific, environmental warnings that were crystal clear at the time when some of these crises could have averted much more easily.” A Sydney Ideas talk on 3 September, 2008 http://sydney.edu.au/sydney_ideas/lectures/2008/blue_covenant.shtml
