Twenty years ago we heard many predictions that there would be no Indians left in Brazil by the end of the decade. These gloomy forecasts were wholly… - Stephen Corry

The tragic destruction of the Gana and Gwi Bushmen reaches into the very roots of humanity and touches not only every human being alive today, but the generations yet to be born. The Gana and Gwi call themselves ’first people of the Kalahari', they might as well say, ’first people of the world'. They have been here longer than any of us. They are the last survivors of the world's first modern humans. It is not up to the Botswana government to wipe them out of history, with nothing more than an arbitrary and cruel presidential directive in favour of just more wealth for the country's elite – and of course the fantastically rich owners of De Beers. We will fight for the Bushmen's right to survive however long it takes. If they lose, then we will make certain that the crimes which brought their end are not expunged, but written large into history. Twenty-first century governments can no longer destroy indigenous tribes with impunity.

Would people still use the same demeaning language talking about European gypsies or immigrants? It is fundamentally an old, 19th-century throwback to the idea that that these people are somehow like our ancestors, or backward. It conveys that they are somehow not as intelligent as we are; that they haven't progressed as far as we have. It is fundamentally a colonial mentality.

Governments, corporations and assorted others regularly exploit the idea that tribal peoples are "primitive" in order to remove them from their land or open it up to outsiders, thereby freeing up access to the natural resources on or under their land. Often this is done in the name of "development", justified on the grounds that the so-called "primitive" tribes are backward and out-of-date and need to "catch up" with the rest of us. But what are the consequences? For the tribes, they are almost always catastrophic: cultural and spiritual alienation, poverty, alcoholism, disease and death.
