One of South America's few remaining uncontacted indigenous tribes has been spotted and photographed on the border between Brazil and Peru.
The Brazilian government says it took the images to prove the tribe exists and help protect its land.
The pictures, taken from an aeroplane, show red-painted tribe members brandishing bows and arrows.
More than half the world's 100 uncontacted tribes live in Brazil or Peru, Survival International says.
Stephen Corry, the director of the group - which supports tribal people around the world - said such tribes would "soon be made extinct" if their land was not protected.
'Monumental crime'
Survival International said that although this particular group
is increasing in number, others in the area are at risk from illegal
logging.
The photos were taken during several flights over one of the most remote parts of the Amazon rainforest in Brazil's Acre region.
They show tribe members outside thatched huts, surrounded by the dense jungle, pointing bows and arrows up at the camera.
"We did the overflight to show their houses, to show they are there, to show they exist," the group quoted Jose Carlos dos Reis Meirelles Junior, an official in the Brazilian government's Indian affairs department, as saying.
"This is very important because there are some who doubt their existence."
He described the threats to such tribes and their land as "a monumental crime against the natural world" and "further testimony to the complete irrationality with which we, the 'civilised' ones, treat the world".
Disease is also a risk, as members of tribal groups that have been contacted in the past have died of illnesses that they have no defence against, ranging from chicken pox to the common cold.FOR MORE INFO OR TO SEE THE PICTURES PLEASE VISIT THE BBC NEWS WEBSITE: http://news.bbc.co.uk/2/hi/americas/7426794.stm
Once the money arrives and is distributed to aid groups and
monasteries, it is used to purchase rice, medicine, fuel and other
supplies required to rescue, house and feed the survivors of the
cyclone. Even in many of the hardest-hit areas, local markets are still
working, with merchants bringing goods from other regions. In other
areas the monks and other groups are able to drive supplies in, or move
them by foot. The map at left shows some key locations where their aid
has reached survivors.ANNOUNCER: Support for Living on Earth comes from the National Science Foundation and Stonyfield Farm.

GELLERMAN: From the Jennifer and Ted Stanley Studios in Somerville, Massachusetts – this is Living on Earth. I'm Bruce Gellerman, in for Steve Curwood. The grim news from Myanmar gets even worse. A hundred thousand lives lost; a million without homes or basic necessities.
Most of the deaths and damage were the result of a 12-foot wall of water that flattened everything in the low-lying Irrawaddy Delta. But scientists say much of the destruction could have been prevented – if only the mangrove forests that protect the coast had not been cut down. Jeff McNeely is Chief Scientist for the International Union for the Conservation of Nature. I want to thank you for joining us.
MCNEELY: My pleasure.
GELLERMAN: What role does the deforestation of mangroves play in the Burma disaster?
MCNEELY: I think it plays a very substantial role. Burma is an incredibly poor country, and they've been forced by desperation to clear the mangroves all the way to the edge of the Irrawaddy Delta. And the result of that has been to remove the buffer that had protected them from storms that periodically come shooting up the Bay of Bengal and the Andaman Sea right into Burma.
GELLERMAN: Well, why clear the mangroves?
MCNEELY: Well, mangroves are worth money if you cut them down, you could make firewood out of them, construction materials, you can use the land for growing shrimp. But it's not really very economic and it's not something that is a long-term benefit. You get a very quick return from cutting down the forest, but you pay a long-term cost, as they're learning right now today.
But the mangroves typically are not owned by individuals; they're public land. And so people who are desperate, and certainly the general population in Burma is very desperate, and they've been forced to do something that they certainly traditionally would have not have done because they know the consequences.
GELLERMAN: Well, so, why did they do it?
MCNEELY: Out of sheer desperation in a country whose economy is tanking while many of their neighboring countries are prospering well.
GELLERMAN: How do mangroves protect a low-lying coastal area?
MCNEELY: Well, so you can imagine a river like the Irrawaddy with a huge watershed that drains most of Burma, and it brings down a lot of sediment. That sediment is deposited as the river slows down when it reaches the sea. The mangroves are what fix the soil as – before it can run out into the middle of the ocean. So along the whole coastal zone of Burma, from one part of the coast to the other, is mangroves because they're able to grow in salt water.
And because they grow in salt water, they're able to protect the coastal zone against further erosion when there are storms. So they fix the soil, they protect against further erosion, and they serve as a nursery for the fisheries that provides much of the protein that goes to feed the people of Burma.
GELLERMAN: So when a cyclone moves up into an area and hits the coastal area, these mangroves basically anchor the soil and help dissipate the energy from the waves?
MCNEELY: Exactly.
GELLERMAN: What do mangroves look like? Are those, those kind of trees, those evergreen trees that have the trunks growing high up into the water?
MCNEELY: Well, they have multiple trunks, you know, it's like a whole bunch of little fingers sticking out, reaching out into the soil. And that's what helps them to capture the sediments and to hold the sediments.
GELLERMAN: What about places like Bangladesh, which is not far from Burma, in the Bay of Bengal. 1991 they lost 140,000 people in a devastating cyclone there. How have they done with their mangroves?
MCNEELY: What they have done is establish a World Heritage Site called the Sunderbans, which is at the mouth of the Brahmaputra and Ganges Rivers, and it really is a bi-national site with India. So the most substantial mainland mangrove in all of Asia is there. And it's also one of the areas that is the best habitat for tigers.
So it's a place where the tigers are being conserved because the government of Bangladesh has recognized the multiple values of the mangroves: for fisheries, for storm protection, and for various minor forest products that can be harvested in a sustainable way. Improved management is basically the answer.
GELLERMAN: You studied Sri Lanka in the aftermath of the 2004 tsunami. What did you learn there?
MCNEELY: The areas where there were solid mangroves, where the mangrove forests were healthy, suffered much less damage than places where the mangroves had been destroyed.
GELLERMAN: So what, if anything, can be done now about Burma and its mangrove forests. What should be done?
MCNEELY: Well I think our first concern has to be for the people. And so we've gotta find a way to get in there and help the people who are being damaged by this environmental destruction. And then as soon as we're able to stabilize the human tragedy, then we should start replanting the mangroves, implementing the legislation that's on the books but isn't being implemented, and putting it into practice to make sure that the mangroves are able to re-grow as quickly as possible. We can certainly help them to do that through the experience we've learned in working to recover the mangroves following the tsunami.
GELLERMAN: Well Mr. McNeely, thank you very much.
MCNEELY: It was my pleasure.
GELLERMAN: Jeff McNeely is the Chief Scientist for the International Union for the Conservation of Nature.

More than half of the world's ocean-going sharks are at risk of extinction, a new analysis concludes.
Specialists with IUCN (formerly the World Conservation Union) found that 11 species are on the high-risk list, with five more showing signs of decline.
Sharks are particularly affected by over-fishing as they reproduce slowly.
The scientists are calling for global catch limits, an end to the practice of removing fins, and measures to minimise incidental catches (bycatch)."There's this idea that because these are widely ranging species, they're more resilient to fishing pressure," said Sonja Fordham, deputy chair of the IUCN Shark Specialist Group (SSG) and policy director for the Shark Alliance conservation group.
"In fact they're becoming species of serious concern because there are no international catch limits for sharks. There are intense fisheries on the oceans, and they remain pretty much unprotected."
New threats
The SSG assessed data on the 21 species of sharks and their close cousins, the rays, that swim in upper portions of the open ocean where they are exposed to fishing fleets.
Of the 21, one - the giant devilray - is assessed as Endangered, and 10 are Vulnerable.
A further five are listed as Near Threatened, which means the signs of decline are not serious enough yet to merit a full listing.
The classifications are based on a range of criteria that look at past or forecast declines in population size. For example, a population shrinking by 50% in 10 years would usually qualify as Endangered.
Some of these species have been assessed before; but for others, including the three species of thresher sharks with their spectacularly long tails, the dangerlisting is new.
Fin cuts
The main threat to sharks is fishing, both accidental and targeted.
"They used to be taken as bycatch by boats targeting tuna and swordfish," said Ms Fordham. "But now as those species are declining we're seeing more fishermen targeting sharks.
"Porbeagle and shortfin mako are targeted for fins and meat; species like blue shark are likely to be finned, but particularly in Europe we're seeing more blue shark being landed."
Several of the bodies that regulate fisheries in international waters - the Regional Fisheries Management Organisations (RFMOs) - have set up measures to curb shark finning, but there are different standards in place, a situation that enables fishermen to work around the regulations.
As East Asian economies boom, conservation groups say the market for fins is increasing.
"Fishery managers and regional, national and international officials have a real obligation to improve this situation," commented Nicholas Dulvy from Simon Fraser University in Vancouver, the report's lead author.
"But it doesn't have to be like this. With sufficient public support and resulting political will, we can turn the tide."
The report was released at the Convention on Biological Diversity (CBD) meeting in Bonn, and will be published in the journal Aquatic Conservation: Marine and Freshwater Ecosystems.
The new risk assessments will be included in the IUCN Red List of Threatened Species when it is published later this year.


Westport, Conn. (May 7, 2008) — As the death toll in Myanmar continues to rise as a result of Cyclone Nargis and as hardships for thousands of survivors left in its wake increase, Save the Children is mounting a rapid response to provide lifesaving relief to children and families in five regions hit hardest by the storm.
The cyclone, which struck Myanmar's southwestern coast early on Saturday, May 3, has killed more than 22,000 people and left more than 1 million people homeless, according to government sources. Save the Children staff in the area report that many villages are devastated, with some up to 90 percent destroyed. The low-lying Irawaddy Delta suffered the effects of a sizable storm surge and many areas remain underwater, hampering efforts to reach families in need. Much of the delta is reachable only by boat.
Since Monday, Save the Children has distributed two metric tons of food, plastic sheeting, water purification tablets, kitchen equipment, rehydration salts and other non-food items to over 50,000 children and families whose homes have been destroyed. Additional trucks left this morning for Pathein carrying food and non-food items.
"Save the Children is mobilizing its 500 employees in 35 offices across the affected region to assist vulnerable children and families who have lost their homes in this most recent disaster," said Ned Olney, Save the Children's vice president for international humanitarian response. "Shelter materials, clean water, mosquito nets and emergency health kits are critical needs at this time—and we are moving quickly to provide these lifesaving items."
Authorities have declared five regions with an estimated total population of 24 million to be in a state of emergency, including Yangon (Rangoon) Division, Pegu Division, Mon State, Karen State and the Irrawaddy Division. This delta is considered to be the country's rice basket and already, the cost of food has doubled in many markets.
"The impending rainy season is likely to complicate an already desperate situation," said Olney. "The current lack of clean water will directly impact the health of children and their parents. And standing water only increases the possibility of an outbreak of waterborne illness. We need to move aid quickly to alleviate current hardships and mitigate the potential for a greater crisis."
Save the Children currently operates programs in all five of the affected regions and has worked in Myanmar since 1995. As one of the largest nongovernmental organizations at work in Myanmar, the agency implements programs focused on early childhood care and development, child survival and child protection. All staff members are safe and accounted for, although their homes and families have been affected.
The cyclone struck southwest Myanmar, formerly known as Burma, earlier this month and the UN believes nearly 134,000 people have died or are missing, while 2.5 million survivors have been affected.
International pressure
Myanmar's military rulers are under growing pressure to accept a full-scale relief operation for cyclone survivors in need of immediate aid.
Thousands of tonnes of aid are being flown in to Myanmar, but relief efforts have been hampered by government restrictions.
In
recent days, Myanmar's rulers have begun to let more foreign experts
into the country, more than two weeks after the storm, but aid groups
still want greater access to help supervise relief efforts. Ban Ki Moon, the UN general secretary, has announced he will visit the country later this week. General Than Shwe, Myanmar's military leader, visited cyclone relief camps on the outskirts of Yangon on Sunday. His visit followed allegations he had shown "indifference" to the country's disaster. Despite
the government's insistence that the relief efforts are going well,
witnesses who managed to slip the security cordon around the hard-hit
Irrawaddy Delta said the situation remains dire. "It was horrible beyond description," said one foreign businessman. "Most of the devastated huts looked like they were empty at first glance, but there were actually survivors inside. "One
hut with no roof was full of about 100 people, crouching in the rain.
There was no food and no water. Each person had nothing more than the
clothes on their bodies, shivering in the cold." 'Man-made catastrophe' Britain's
Asia minister said he thought efforts would soon pay off, with an
agreement likely for a UN and Asian-led operation that could solve the
impasse. "I
think we're potentially at a turning point, but like all turning points
in Burma, the corner will have a few S-bends in it," Mark Malloch-Brown
said. But
the minister's optimism follows comments by Gordon Brown, Britain's
prime minister, who earlier labelled the military's holding back of aid
as "inhuman" and said what had been a natural disaster was becoming "a
man-made catastrophe". John
Holmes, the UN's emergency relief co-ordinator, was due to arrive in
Myanmar late on Sunday to assess the situation and plead with Myanmar's
military leaders for greater co-operation with relief agencies. A
day earlier, officials gave a guided tour of the country's cyclone-hit
regions to foreign diplomats and aid workers based in Myanmar. The
diplomats were taken into an area which has been closed off to
foreigners, but it was "not good enough to get a clear picture of the
damage", according to one diplomat. "What
they showed us looked very good, but they are not showing us the whole
picture," Chris Kaye, Myanmar director for the UN's World Food
Programme, said. As
pressure mounts on Myanmar's allies to exercise their power, Southeast
Asian foreign ministers are due to meet in Singapore on Monday for
talks on how to deal with their neighbour.
