The masai. Unfortunately they are portrayed as coffee table book tribal heros not the morons most of them are. This summer a goat was killed in nairobi National park by illegal masaai grazers - their response was to kill 6 lions in retaliation. That takes out the entire gene pool of that territory. This story happens across east africa more frequently than you might imagine. Kenya is down to about 2,000 lions and that number is dropping primarily due to livestock grazing conflicts. The only success stories on this are in the unfenced conservancies in Mara North, Olare Orok etc where the tourism "rents" land from the masai for photo tourism. The models where compensation is paid for livestock deaths from wildlife is open to abuse and the areas where no comp is paid seems to be working far better.
Sparks hounds - you are right about the asian influx - they own and control most of east africa. You could argue we used to so we can't complain but I would like to think that in these more enlightened times we wouldn't let that continent get raped of all its natural resources PURELY for export. As soon as the new port opens up Sudan the problem is going to get exponentially massive. Our oriental friends realised that you can literally buy anything/ anyone in africa and they are making good use of it. Our consumer lifestyles for stupid iphones etc fuel the demand for the exploitation of mineral deposits which we gleefully buy from the East.
There are too many examples to list here but here is one: The Selous Game reserve - the largest game reserve in Africa. A UN world Heritage site. The new location for the worlds largest open cast Uranium mine. It will be the size of Oxfordshire. It will be owned and run by the Chinese. Add to that the elephant poaching in the Selous and it seems the chinese are hell bent of destroying it as fast as possible:
Tanzania's elephant population declined by more than 30,000 elephants between 2006 and 2009, primarily from poaching to supply black-market ivory to Asia. Rampant poaching is concentrated around the Selous Game Reserve where 40% of Tanzania's elephants are located
