Flights

As global warming threatens the future of our society, Jo Fidgen tackles the ways in which ordinary people can make a difference.

We're often told that we could help the environment by driving less, eating less meat, or using less water.

But in the face of a challenge as significant as global warming, how big a difference can small changes really make? And what would the world look like if we took those solutions to their logical extremes?

In this episode, Jo considers air travel. Not many people - at least globally - fly. If you do, it's probably your single biggest contribution to greenhouse gas emissions. But what would it mean for the world if we decided to stay grounded?
