NASA Earth Observatory - Fires Along Xingu River, Brazil


The rainforest of South America, also known as Amazonia, has been undergoing a continual and accelerated conversion process into farmlands (including pasture for livestock) since the early 1960s. This process has typically been achieved by clearing the forest using fire—“slash and burn”—followed by planting of crops. The generally infertile soils of this rainforest—the largest such forest on Earth—make sustainable farming difficult. This drives people to convert more forest into farmland. The area of clearing can be considerable, and since the deforested regions are easily identifiable and measurable from space, the rate of deforestation is likewise easy to track.

This astronaut photograph illustrates slash-and-burn forest clearing along the Rio Xingu (Xingu River) in the state of Matto Grasso, Brazil. The photo was taken from the International Space Station, a platform from which astronauts can capture images of the Earth from a variety of viewing angles. The perspective above shows both the horizontal position and the extent of the fire lines next to the river, while also providing a sense of the vertical structure of the smoke plumes.

Light colored areas within the river channel are sand bars, which show that the river is in its annual low-flow/low-water stage. For a sense of scale, the river channel is approximately 63 kilometers (39 miles) long in this view. Rivers are the natural highways in Amazonia, which may explain why the burning is occurring right next to the Xingu River, one of Amazonia’s largest.

1. Not good
logic tells me that we will destroy this planet unfortunately. and likely within a couple hundred years - unless there is some mass awakening in people regarding the environment. :(

2. No, not at all good.
We have already seriously compromised the planet's ability to support some forms of life - possible even our own. The next two decades will tell an interesting tale.

There is in fact a massive, global awakening already under way. Not just regarding the environment either, though that's what triggers it in a lot of people. It takes in the social justice, indigenous rights and pure spiritual arenas as well. A whole lot of people are waking up, world-wide. It's the most amazing thing you can imagine, once you understand how to see it. Check out Paul Hawken's book Blessed Unrest for a good description of it.
