The challenge of a growing population

Available for over a year

With Earth's population set to grow 25% by 2050, we ask how people will be accommodated. Hannah Olmberg-Soesman, co-founder of solar energy business Guguplex Technologies, Olivia Feng of software company ICAN Future Star, and Professor Klaus Lackner, director of the Centre for Negative Carbon Emissions at Arizona State University discuss the issues. Also in the programme, new UN research by more than a hundred scientists around the world warns of the increasing devastation climate change will inflict on coastal megacities and small island nations. Brian Klinksiek is strategy director at US property investment company Heitman, and gives his perspective on what the scientists had to say. Plus Beijing's newest airport Daxing International opened today. Professor Hangjun Yang at Beijing's University of International Business and Economics tells us what visitors can expect to see.
