Access to clean water is recognised by the United Nations as a human right but the World Economic Forum says drinking water shortages will be one of the biggest threats the planet will face over the next decade. Multi-national beverage companies are investing heavily in bottled water and see it as a lucrative market. Why are they allowed to profit from a natural resource? Roundtable is a discussion programme with an edge. Broadcast out of London and presented by David Foster, it's about bringing people to the table, listening to every opinion, and analysing every point of view. From fierce debate to reflective thinking, Roundtable discussions offer a different perspective on the issues that matter to you. Watch it every weekday at 15:30 GMT on TRT World.
