How to suck 2 gigatons of carbon from the atmosphere

Fast Company article on how enhanced root crops like Kernza could mitigate carbon.

“If plant breeders develop new crops with deeper, longer roots, that could potentially also help capture more carbon as the roots reach deep underground. (One crop of this type, called Kernza, already exists and is used in products like Long Root Pale Ale, a beer that Patagonia markets for its ability to help capture carbon). By 2050, though the report says “estimates remain highly theoretical,” crops like this could potentially remove as much as 185 megatons of CO2 each year.”
