I wrote about it before : deforestation in the Brazilian part of the Amazon rainforest – aka the lungs of Earth – decreased by no less than 46 percent and is at record low levels in the past two decades.
These are surely good news as deforestation is a predominant part in Brazilian greenhouse gases emissions. TreeHugger explains how this was achieved, partly thanks to satellites.
As a science fiction fan I like it when space technology helps solving Earth matters. This isn’t the first time it happens.
