If keeping the “genetic diversity” (non human introduced, that is) means to starve the Africans, why let’s starve the Africans!
(...somehow they forgot that the old hybrid grain seeds are also genetically modified, just in a more traditional low-tech way.)
For some in the Green Left, starving the Africans is the bottom line. They consider “overpopulation” the greatest threat facing the world, so if something “culls the surplus population,” it’s good in their eyes. Gates has funded population groups — but he is a heretic from the Green religion on this.
