Well, once again, thanks to all who took the time to spread the word about the current plight of the Hadzabe. Duane at Abnormal Interests actually took the time to call the US State Department and was successful in reaching two individuals in the Bureau of African Affairs. You can read more about it at Duane's blog. I received an email from the State Department in response to my email inquiries, but it was the usual bureaucratic form letter along the lines of "thank you very much for your concern...the State Department values all feedback...should you require further assistance...yada, yada, yada..." - so, altogether not very helpful. Duane's efforts I'm sure made more inroads. I have heard nothing from Cultural Survival nor Survival International.
I am also in touch with the chairman of the German branch of FPCN (Friends of Peoples Close to Nature) whose organization has been highly involved with the Hadza. A reader also left me a message saying that she had written NBC, ABC and BBC - she and her husband had recently visited the Hadza and was appalled at the efforts to displace them.
Thanks again for everyone's efforts. I will keep you posted should there be any new developments.
