This is a film about a technique that could save more carbon emissions annually than all global aviation combined. It is a film about one of the biggest contributors to tropical deforestation and global warming: slash and burn agriculture. It sits at the crossroads of two of the greatest threats to global stability: accelerating climate change and diminishing food security. The film follows British scientist Mike Hands, who has laboured for 25 years to perfect a sustainable farming technique to replace slash and burn farming in equatorial rainforests.

And he’s found it.
