Last year, Bono accepted an award from TED, an exclusive and enlightening conference in the technology, entertainment, and design communities. Previously unreleased, Bono's stirring talk loudly outlines the importance of a social movement for Africa, including his efforts with the One Campaign. I've highlighted a few key moments from his speech here:

It's not a cause, it's an emergency. This is not about charity, this is about justice. Justice is a tougher standard than charity. Catastrophes that we can avert are not as interesting as ones we could avert. Funny that. Equality for Africa is a big, expensive idea. What on earth can we all do about this? Well, much more than we think. The fact is ours is the first generation that can look disease and extreme poverty in the eye - look across the ocean to Africa - and say this and mean it: we do not have to stand for this. Working together, we can actually change the world. Where you live in the world should not determine whether you live in the world. History, like God, is watching what you do.
