Population control is a misguided concept, and has a grim history, ranging from mass sterilisation in India to the "lebensraum" idea of the Nazis. It's not a sensible path, and is mostly tied to extreme ideologies and Malthusian pseudo-science.
Pointing to Uganda, whose citizens represents probably about 1% of emissions per capita compared to the west is is crazy to me. How can one even excuse ones own high consumption levels while blaming Ugandans for reproducing, when one represents the same amount emissions as that of a small village in some places?
