It is our all generations' responsibility to work together in the whole world to prevent such atrocities happening again.
It is Africa, and as much as it sucks for the people there, it has always been so and will properly be so long after we are gone.
And no, there is nothing special about Africans, but a lot that is "special" about Africa. The rampant disease. The widespread corruption. The poverty resulting from those. The political boundaries that are a remnant of European map making rather than any sort of internal logic. These have contributed to generations of misery, and there is no immediate prospect of this changing.
The best thing for Africa imho currently would be a big fence around it, and a label on the gate reading "Do not open before year 3000 AD. Sincerely, the people of 2000 AD."
