Burn: Using Fire To Turn Down the Heat
Available on backorder
A secret unlocked by the ancients of the Amazon for its ability to transform impoverished tropical soils into terra preta – fertile black earths – points the way. The indigenous custom of converting organic materials into long lasting carbon has enjoyed a reawakening in recent decades as the quest for more sustainable farming methods has grown. Yet the benefits of this carbonised material, now called biochar, extend far beyond the soil. Pyrolysing carbon has the power to restore a natural balance by unmining the coal and undrilling the oil and gas. Employed to its full potential, it can run the carbon cycle in reverse and remake Earth as a garden planet. This book looks beyond renewable biomass or carbon capture energy systems to offer a bigger and bolder vision for the next phase of human progress, moving carbon from wasted sources.
