Not even remotely true. This is part and parcel of Agenda 21.
In the 1970s, Rhodesia all by itself produced enough food to feed most of Africa. The political destruction of Rhodesia and South Africa was engineered with Agricultural destruction as the primary goal.
Just because not every conspiracy is real ... that does not mean no conspiracies are real.
As I recall, Alan Keyes was the one warning about starvation coming to Rhodesia before anyone else saw it.
He was ignored.
Kind of interesting considering the fact that Cecil Rhodes was a fabian socialist and the nation named after him falls the way it has.
