In prehistoric times, the aquatic fern azolla drew down massive amounts of atmospheric carbon and helped create the livable climate we enjoy today. Chris Tebbutt of Filigreen Farm calls for growers to cultivate this native plant for nitrogen production and carbon sequestration. Chris explains how it serves a very practical on-farm purpose while sequestering CO2 at astounding rates. He closes with a pitch for 'geotherapy', based on the work of Dr. Thomas Goreau (youtube.com/watch?v=oTMiii-BRtU).
