That's not to say stopping deforestation isn't also a climate priority ?" scientists say we should totally do that too. Every year, people across the globe chop down about 15 billion trees to make room for agriculture and other forms of industry. In the Amazon rainforest, a crucial part of our carbon-curbing toolkit, deforestation has shot up by 278 percent. That's largely a result of the pro-agribusiness policies of Brazil's new, far-right president, Jair Bolsonaro. The authors of the IPCC report say that not only do we need to plant more trees, we need to stop tearing them down.
