AMAZON RAINFOREST CATCHES FIRE, 2 MIL SQ KM THREATENED! "SUICIDE NOTE OF MANKIND" - PREZ CANDIDATES? [View All]

Vast areas of Brazil and Paraguay and much of Bolivia are choking under thick layers of smoke as fires rage out of control in the Amazon rainforest, forcing the cancellation of flights.

Satellite images yesterday showed huge clouds of smoke and much of the Amazon basin burning as fires, originally set by ranchers to clear land, have raged into the forest itself.

From Santa Cruz in the east of Bolivia, where flights have been grounded, to the Brazilian frontier city of Porto Velho, where the river Madeira has been made unnavigable, burning smoke has blocked out the sun and local communities have begun to complain of respiratory disorders.

Roberto Smeraldi, head of Friends of the Earth Brazil, said the situation was out of control: "We have a strong concentration of fires, corresponding to more than 10,000 points of fire across a large area of about two million sq km in the southern Brazilian Amazon and Bolivia."

Each year at the end of the dry season, in anticipation of the first winter rains, farmers and cattle ranchers throughout South America set fires to "renovate" pasture land. But this age-old cycle has spun out of control as deforestation and climate change have created a tinderbox. There has also been a massive expansion of cattle ranching into forested areas, where fires are then set to clear an area after chainsaws have felled the trees.

Mr Smeraldi was clear on who was to blame for this year's fires: "They are mainly, I would say more than 90 per cent, the result of expanding cattle ranching." The first rains have arrived but they are weaker than usual in most areas and have been useless against the fires.

In the past three years Brazil's National Development Bank and the World Bank have poured funds into the southern Amazon, fuelling the expansion of the cattle industry with new slaughterhouses and four million additional head of cattle arriving in exactly the areas where the fires are now. Conservationists have said that while governments insist they are doing their utmost to stop deforestation they have been putting in place incentives for the destruction of the forest. "It is taxpayers' money fuelling these fires," said Mr Smeraldi.

"Disintegration of the Amazon forest, with release of the carbon stocks in the biomass and soil, would be a significant factor in pushing us into a runaway greenhouse."

"It's not out of the question to think that half of the basin will be either cleared or severely impoverished just 20 years from now," added Dr. Daniel Nepstad, head of the Woods Hole Research Center's Amazon program. "The nightmare scenario is one where we have a 2005-like year that extended for a couple years, coupled with a high deforestation where we get huge areas of burning, which would produce smoke that would further reduce rainfall, worsening the cycle. A situation like this is very possible. While some climate modelers point to the end of the century for such a scenario, our own field evidence coupled with aggregated modeling suggests there could be such a dieback within two decades."
