This year is on track to be the worst on record for forest fires in the Amazon, per the Brazilian government. The fires are doing the most damage in the areas of the forest already hit by human-caused forest degradation, Mongabay reports.
- Distinct from deforestation, forest degradation is the process of felling just the valuable trees in a forest and leaving behind flammable tree limbs and debris, creating a ground zero for wildfires.
- Why it matters: Climate change, deforestation and forest degradation are causing mega-fires that are devastating large swathes of the Amazon rainforest. Carbon emissions from the fires have the capacity to impact climate around the world.
