When Professor Tom Crowther published research into the massive potential of trees to absorb more carbon than previously thought, he helped spur the Trillion Trees movement to plant, restore and conserve forests. But it also caused massive debate.

As he publishes updated research, Crowther tells Radio Davos that growing trees must increase biodiversity, and not lead to monoculture plantations, and that it must never be an excuse to slow the drive to eliminate greenhouse gas emissions.
