WHY THE AMAZON
Not the planet's lungs - its thermostat.
The Amazon is the planet's thermostat and water pump. It stores immense carbon, and parts of it are shifting from a carbon sink to a carbon source. Its flying rivers recycle the moisture that generates rainfall for South America's agriculture.
Scientists warn that by 2050, between 10 and 47 percent of the Amazon could cross a tipping point toward irreversible collapse. Protecting it is not about oxygen - it is about a stable global climate.
