I start with the problems in practice. And maybe that's why I'm less tolerant of some of the fuzziness and some of the ambiguity in IWRM the way it's been written about and the way it emerged. I mean calling water and economic good leads to the notion that you should get the prices right if you want to protect the environment, if you want to protect the water. But as soon as you start talking about getting the prices right, you're assuming water is a commodity. And if you think water should be a right, then the price is not relevant. And thinking of it as an economic good is not helpful. And some of you know, I'm working on the problem of water shutoffs in American cities, where people who can't pay their bill for their water for a month or two have their water shut off. Well, they can't pay their bill because they're out of work. And telling them they have to pay their bill isn't going to make it possible for them to pay their bill. And then the next thing that the water department does is it calls the family services department and says take the children out of that home. There's no water there. It's that's not hygienic. So their kids are taken away. They still can't pay the bill. And then the next thing that happens is the city puts, sells the lien, it's an economic instrument, on the debt. Because the city needs money to pay to maintain the water system. And if people don't pay their bills, it doesn't have the money
