Usual propaganda, just like the BMWF ads you see everywhere, it's all about trying to convince the whites, especially young women (who can/will carry black children) and the next voting generation, to accept the endless waves of niggers invading and replacing their ageing population. In countries like Germany or Italy, the natives women have in average 1.3 kids. Way below the replacement ratio. The only exception being France, and it's only because their country is filled with packs of niggers. Meanwhile in Congo or Togo the average is 7.9 kids per woman. The subafrican population average age is 15 years old. In europe it's 43 years old. Europe population is dying, and instead of putting in place natalist policies, the traitorous elites decide to import their next wageslaves, dumber and accepting pretty much anything, perfectly fit to serve their masters in giant factories with brainless tasks without going on strike.
By 2050 half the population growth will be added by africa alone. In 1900 Africa had 100 millions inhab. Today it's 1.2 billion, 12x growth in a century thanks to the white man industries, vaccines, food and infrastructure. In 30 years it's projected to be 2.3 billions.
While in europe the numbers will be dwilling and the average population will be 50+ years old.
The situation will soon be totally untenable in Africa, the continent can't sustain such population growth with the actual infrastructures. You have to remember 95% of the sub saharan infrastructure (hospitals, farms, roads, trains, power grid..) was built by the white men during colonisation. And since the decolonisation, nothing replaced it or even just the upkeep wasn't done. Everything in black africa is in ruins beside few enclaves where the local warlords or corrupted politicians can trade natural resources for white infrastructure.
And the problem isn't just technologic, most of black ruled countries can't get their shit together because the politicians are so corrupted.
