Drivers of deforestation and forest degradation by region, 2000–2010, from the Food and Agriculture Organization publication The State of the World's Forests 2020. Forests, biodiversity and people – In brief [3] Deforestation is much worse than forest degradation, but it is clear and visible.
The main cause is the decline in deforestation rate in Brazil, due to the government's policies, while Columbia, Peru and Bolivia also reduced deforestation.

Satellite photograph of deforestation in Bolivia.Originally dry tropical forest, the land is being cleared for soybean cultivation. [5]Biodiversity hotspots are chiefly tropical regions that feature high concentrations of endemic species and, when all hotspots are combined, may contain over half of the world's terrestrial species.

Deforestation is one of the main causes of anthropogenic carbon dioxide emissions, making it one of the largest contributors to climate change. Though preserving old-growth forests is most effective at maintaining biodiversity and ecosystem functionality, secondary forests may play a role in climate change mitigation . [ 6 ]
