Furthermore, when previously uncultivated land, including tropical forests, is brought into cultivation, large amounts of carbon are released from the soil, worsening the carbon dioxide balance.

The Breakthrough team warns that while deployment of today's technologies is vital, if money for deployment is included in the $ 150 - billion pie, that dangerously reduces the amount of money for laboratories pursuing vital advances on photovoltaics or energy storage and for big tests of technologies that must be demonstrated at large scale — like capturing carbon dioxide from power plants.
