“The largest tropical forest on Earth, the Amazon stores more than 120 billion tons of carbon, which — if unleashed into the atmosphere — would supercharge climate change. It’s also home to a mind-boggling number of plant and animal species, many of which have served as the basis for medicines to fight ailments like cancer and hypertension.
That’s what makes this so alarming: The Amazon forest is dying. Decades of deforestation, wildfires, and rising temperatures are pushing the forest toward a critical threshold of destruction beyond which large parts of the rainforest will dry out and turn into a savanna, releasing massive quantities of carbon in the process.”
