There are multiple threats to the Amazon rainforest that are very serious, yet three of them appear to be at the forefront of the list: deforestation, climate change, and forest degradation through fire, mining, roads, and other human actions. All these issues are undermining one of the most valuable ecosystems on the planet. The Amazon is a storehouse of carbon, extraordinary biodiversity, and contributes to the rainfall regulation of much of South America, so any harm caused to it has ripple effects well beyond the forest itself.

Deforestation is the greatest problem. Big chunks of forest are deforested to allow cattle ranching, soybean farming, and other agricultural activities. WWF reports that agriculture is the most common source of deforestation all over the world and the Amazon has already lost a good portion of forest cover due to human activity. UNESCO also mentions that an area of almost 1,000,000 square kilometers of Amazonian forest has been devastated during the last 30 years, mostly to establish pastureland and areas where soybean can be grown. Once trees are cleared on this magnitude, wildlife is deprived of a habitat, the carbon that is stored in the forest is emitted to the atmosphere and the rainforest becomes weaker as a whole.

Climate change is the second significant problem. The Amazon relies on a thin layer of heat, moisture and rainfall. The consequences of the increase in temperature and changes in weather patterns are escalating drought stress in most of the region, thereby rendering the forest less resilient and more susceptible to fire. This issue is also contributed to by the loss of forest, as the fewer the trees, the less moisture that is recycled into the atmosphere. That is, deforestation and climate change are mutually aggravating. Deforestation and rising wildfires have also been warned by the IPCC with great confidence that it is a significant cause of climate change due to its release of greenhouse gases and a decrease in the carbon sink capacity of the land.

The third problem is that of forest degradation not necessarily as visible as clear-cutting but can be equally harmful in the long run. Degradation occurs when the forest is debilitated through logging, frequent fires, mining, road fragmentation and other disturbances that fail to clear the forest totally but diminish its health and ecological quality. Scientific studies have discovered that the Amazon is becoming more degraded and, in certain regions, it could be even greater than deforestation. This is important since a damaged forest will hold less carbon, fewer species and may lack the ability to survive damages in the future.

The three issues are intertwined. Deforestation puts in the way path of hotter drier conditions. Drought and fire risk are aggravated by climate change. The degradation undermines standing forests. To protect the Amazon, it will involve stronger enforcement, improved land-use planning, providing support to Indigenous and local communities, and economic models that are not reliant on destroying the forest. Otherwise, one of the most valuable natural systems on earth will be further depleted.
