Matt Ridley has pointed out that agricultural innovations, such as genetically modified organisms (GMOs), allow us to grow more food on less farmland, and thus return more farmland to forests.
(p. D6) A new study reports that recently established forests on abandoned farmland in Latin America, if allowed to grow for another 40 years, would probably be able to suck at least 31 billion tons of carbon dioxide out of the atmosphere.
That is enough to offset nearly two decades of emissions from fossil-fuel burning in the region.
