This episode of The Green Interview features Maude Barlow, a Canadian environmental activist and author who argues that water is the next oil. As chair of the Council of Canadians, Barlow led a public fight against the North American Free Trade Agreement (NAFTA) in the 1980s and for over a decade, she has focused her boundless energy on a crisis of global proportions: the looming world-wide water shortage, which is accelerated by free-trade deals that privatize water. She says the Canadian government’s new free-trade deal with Europe signs away people's water rights and gives up local control over provision of water and other provincial-municipal services. In this Green Interview, Barlow discusses the world's dwindling water supplies and explains the implications of CETA—Canada's tentative Comprehensive Economic and Trade Agreement with Europe.
