I would like to address the issue of poverty, starvation, birth control issues, disease, warfare, lack of education, and lack of proper medication that arises when you examine Africa. I still find it relatively difficult to believe that one continent is so far behind the others, but I suppose that's what happens when their borders and tribal boundaries are completely neglected when European countries exploited their people for labor and profit, and then left the continent, with the hopes that it wouldn't fall to pieces.
Neil Degrasse Tyson put it eloquently when he examined how, in the earlier states of mathematics and all intellectual progress (the invention of Algebra, examination of the number '0', numerous contributions to engineering), the Arabs were ahead of everyone else. Baghdad, around 1000 A.D, was the intellectual haven of the world, where everyone was welcome to express their knowledge without scrutiny of any religion, which might suppress their findings at the time.
(Notice how our numbers are called 'Arabic' numerals).
Hamid Al-Ghazali, an Arabic and Islamic scholar, introduces the widely devoured philosophy that mathematics is the work of the devil. From that point forward, the whole intellectual community of the Middle East collapses, and has never recovered from this state.
Neil Tyson emphasizes strongly how, since the installation of the Nobel Prizes, there have been two Muslim winners, one of which was from Pakistan, yet Jews have won upwards of 1/4 of the Nobel Prizes. Proportionally speaking, almost every one of those Nobel Prizes should be given to Muslims, because of the ridiculous number of people in the world who are Muslim.
I essentially see that same scenario happening with Africa, but instead of it being fueled by fear of religious persecution that smothers intellectual progress, it's a staggering lack of necessary and fundamental tools for life that is potentially stopping any contributions from Africa. If you choose to look at it this way, then instead of only bettering the lives of humans who are in despairingly cruel situations, you are also tapping into the intellectual power held within an unjustly impoverished continent.
