Is the world running out of room? Earth's population could reach 11 billion by 2100. Are we pushing the planet to breaking point? Or are fears of overpopulation overstated? Joining us at the Roundtable is Liz Allen, a demographer; Bill Ryerson, President of the Population Media Center; Alistair Currie, the Head of Campaigns and Communications for Population Matters; and Lloyd Msipa, the Director of the Africa Public Policy Research Institute. 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.
