What place for hunter-gatherers in Millennium Three?

"This book takes a hard look at the traumatic cultural changes that our planet's remaining hunter-gatherer societies experienced in the twentieth century, and the precarious future that is about to engulf them in the twenty-first century. ... Case studies are presented here looking at the past and the uncertain future for post-foraging societies in Africa and Asia, and specifically the central African Pygmies, the San Bushmen, and the Agta Negritos"--P.
