With critical problems plaguing the Amazon rainforest, South American presidents and ministers will converge on the city of Belem, near the mouth of the Amazon River, from Tuesday to discuss how to address them and how to chart a common course forward.The Amazon rainforest is twice the size of India. It spans eight nations and one territory, houses remarkable biodiversity and freshwater reserves, and is a vital carbon sink. It’s also home to tens of millions of people.Governments have historically viewed the Amazon as an area to be colonized and exploited, with little regard for sustainability or the rights of its Indigenous peoples.
