Survival International, an organisation supporting tribal peoples, last week handed a petition of 40,000 signatures to the Brazilian embassies in London and Madrid urging the Government to protect the land of the Awa Indians, Brazil's last surviving hunter-gatherer tribe.
This comes after a 20-year campaign by Survival to protect the tribe.
Since the early 1980s, settlers have invaded the Awa land killing many of the tribe - only 300 remain.The signatures were gathered from Survival supporters all over the world. Survival also worked with Brazilian NGOs to organise a letter-writing campaign to Brazilian officials. Fiona Watson, campaign co-ordinator at Survival, said: "You should never give up, even after 20 years," she said.
