Amazon rainforest finds unlikely guardian
The area is roughly the size of Great Britain and represents one-tenth of Brazil's rainforest.
This week the Brazilian government will announce plans to buy up and protect vast tracts of the Amazon rainforest with help from the World Bank.
The bank has promised to finance the purchase about 10% of the rainforest - an area roughly the size of Great Britain - to protect it from the encroachment of hardwood loggers, ranchers and mineral prospectors.
The purchase marks a significant departure for the World Bank, which has been criticised in the past for funding vast infrastructure projects that harmed the rainforest.
Meanders for 4,000 miles
Figures describing the rainforest are hard to take in. One thousand tributaries run into the Amazon, which meanders for nearly 4,000 miles and deposits 170 billion gallons of water an hour into the sea. That's 60 times more the volume of water carried by the Nile.
The Amazon area, which covers parts of Venezuela, Peru and Bolivia, covers 2.7 million square miles.
A typical four square mile patch of jungle contains 750 species of tree, 400 types of birds and 125 mammal species.
But the rainforest has been on the retreat for years. In 1987, at the height of the "slash and burn" offensive, 320,000 square miles of jungle were razed.
In recent years, that figure fell gradually to around 11,000 square miles a year. But new satellite data suggests burnings are up again this year by 28%, possibly as a result of Brazil's economic recovery.
Environmentalists fear the loss of the rainforest's unique biodiversity. They point out the Amazon is home to plant species which provide everything from chocolate to today's most important medicines. And they warn that if the area is destroyed, its untold secrets will never be revealed..
The destruction of the forest also poses a huge global climate threat.
Scientists believe global warming will speed up because the vast amounts of cloud produced by the jungle help mask the heat of the sun.
The World Wide Fund for Nature (WWF) is at the forefront of the World Bank deal, details of which will be announced simultaneously on Wednesday in Brazil, the US and Britain.
WWF spokesman Ed Wood-Matthew says the area that would be protected is "absolutely massive" and the sums involved huge.
Huge foreign debt
Mr Wood-Matthew says the deal, which has been agreed by the head of the World Bank James Wolfensohn and Brazil's President Fernando Enrique Cardoso, would not add to the country's foreign debt of around £65bn ($110bn).
He says: "The World Bank agreement means they will really have the resources to make it work."
Mr Wood-Matthew says previous Brazilian governments have made a string of "broken promises" on combating deforestation but he is confident this will not be another.
