UN-Water Chair Gilbert Houngbo remembers being a college student in the late 70s, when people first started saying water should be treated as a public good. Today, we're still having that same conversation, but now, groups like UN-Water are working to make it a reality.

On GZERO World with Ian Bremmer, Houngbo emphasizes the importance of policies that ensure access to basic water services, encourage water reuse, and minimize the risk of pollution. It's easy to think water is free and we don't need to take care of it, says Houngbo, "but this has to stop."
