The explorer and documentary maker Bruce Parry pushed his penis inside his body on his 2005 BBC show Tribe in an effort to be accepted by the Kombai people in New Guinea, before turning white and having to lie down. He would do whatever it took to assimilate, including taking hallucinogenic drugs, drinking blood and running naked across the backs of a row of cattle.
Now he is focusing his energies closer to home. He is using the knowledge he gained from Indigenous societies around the world to encourage people in the UK to form stronger communities that can take meaningful action to halt ecological destruction.
