A Debate on Geoengineering: Vandana Shiva vs. Gwynne Dyer
Supporters of geoengineering have proposed radical ways to alter the planet to decrease the level of greenhouse gas emissions.

We host a debate between Indian environmentalist, scientist, philosopher and eco-feminist, Vandana Shiva, and geopolitical analyst and columnist, Gwynne Dyer.
