The Brazilian Amazon, home to 60 percent of the world’s largest forest and 20 percent of the earth’s oxygen, remains threatened by the rapid development of the country. The area is currently populated by over 20 million people and is challenged by deforestation, agriculture, mining, a governmental dam building spree, illegal land speculation including the occupation of forest reserves and indigenous land and other issues.(Mario Tama/Getty Images)
