Peter Gleick: Probably in my opinion the worst 'crisis' around freshwater is our failure to meet basic human needs for so many people.
You're listening to Peter Gleick, an environmental scientist and head of the Pacific Institute, a water think-tank in California. Gleick told EarthSky that more than a billion people worldwide don't have access to safe drinking water — something many of us in richer nations take for granted, he said.
Peter Gleick: [---1---] And that leads to water-related diseases. It leads to many, many deaths of mostly small children. [---2---]
Another challenge is water scarcity. [---3---]
Peter Gleick: Well, Agriculture is the key to all this, in part because we have to grow enough food to feed the world's population. [---4---]
He added that we can no longer manage our water like we did in the 19th century, or even the 20th.
Peter Gleick: [---5---] We'd drill another ground water well. We'd basically look for more supply. And I just don't think in the coming years that there's much more new supply to be had. (重復的只寫一次,磕巴的只寫最后主要說出來的那個詞)

And there're 2.5 billion people, probably 40% of the world's population, that doesn't have access to adequate sanitation services.
And it's a crisis because it's bad, but it's preventable.
Gleick said that can be addressed by finding ways to grow more food with less water.
And second because 80% of the water that humans use goes to agriculture, much of irrigated agriculture.
I think the way we operated in the 20th century, the idea was if we had a water problem, we'd find a place to build another dam.
