I've heard of some Nigerian groups who are striving to make a difference, despite significant hurdles. For example, I've read about an organization called "Save the Children" that is striving to improve healthcare access and nutrition for Nigeria's children. I've also heard of the work of "Doctors Without Borders" in Nigeria, which provides medical care to those in need. These are only two instances of groups making a difference; there are many more.
Doctors Without Borders is Médecins Sans Frontières, a French NGO that is funded by more than 50% just by private donations from US and Germany.
Save the Children is a UK NGO, that got 1 billion in funding from US alone.
Kind of ironic to see that the only good examples are still run by the ones the population blames for everything wrong.
