Scientific American discusses how Carbon Farms may reverse global warming.
German researchers have been looking for a way to take CO2 out of the air, not just ameliorate carbon emissions. They suggest planting the Barbados nut (picture above) in dry costal or desert areas, space that is not used for food production. This plant is known for growing in sandy soil and is predicted to absorb massive amounts of carbon. The study suggests that if 730 million hectares of land, three fourths of the United States, were used to plant the Barbados nut, rising CO2 trends would be halted. The researchers chose this particular plant because it can grow with high levels of contamination in the soil and wastewater can be used to irrigate it.
