The inanity of population growth projections

Current projections of population growth are absolutely ridiculous. Africa - where tens of millions already rely on food aid for nourishment - is expected to double it’s population between now and 2050, from 1.25 billion to 2.5 billion people.

I understand there is momentum to fertility levels but clearly the number of deaths caused by famine / extreme weather events is wildly underestimated.

What is your prediction?

Edit: People are getting the wrong idea, of course Africans are not the problem. Their GHG emissions are very low compared to my countrymen for instance. I used Africa as an example because it’s the most obvious example of unsustainable population growth projection. By 2050 NA is expected to have 0.43 billion people to sustain, but Africa should manage five times more than that?!
