There are an estimated 350 million indigenous people in the world, speaking 5000 languages, and living in 70 different counties. The Lancet has recently published a series on indigenous health.
The Lancet writes,
Major international policies such as the Millennium Development Goals (MDGs), which were set up to target the world’s poorest people could, as they currently stand, actually lead to entire populations of Indigenous peoples being wiped out forever. Minority groups such as Indigenous peoples could be ignored because of the way the MDGs work—by focusing on big numbers and encouraging targets to maximise health benefits for the majority.
Besides their many other problems, these are also the people who in many instances lost land rights when protected areas were established.
