The Amazon, the largest, most biodiverse tract of tropical rainforest in the world, an irreplaceable ecosystem, is being burned, writes Joe Fallon. Set afire intentionally for profits by logging, mining, and agribusiness interests (cattle ranches, soy and palm oil plantations), and by Brazilian colonists who invade indigenous lands to engage in "slash and burn" farming. "The non-indigenous population of the Amazon is exploding. From the 1960's until the late 1990's, this number grew from 2 million to around 20 million." The corporations and the colonists achieve short-term gains that produce long-term losses. The result "...is chaos. Chaos, chaos, chaos," lamented one senior official from Brazil's environmental agency, Ibama" who spoke on the condition of anonymity.
