An excerpt from President Obama's speech at the University of Cape Town:

We believe that societies and economies only advance as far as individuals are free to carry them forward. And just as freedom cannot exist when people are imprisoned for their political views, true opportunity cannot exist when people are imprisoned by sickness, or hunger, or darkness.

And so, the question we've been asking ourselves is what will it take to empower individual Africans?

For one thing, we believe that countries have to have the power to feed themselves, so instead of shipping food to Africa, we're now helping millions of small farmers in Africa make use of new technologies and farm more land. And through a new alliance of governments and the private sector, we're investing billions of dollars in agriculture that grows more crops, brings more food to market, give farmers better prices and helps lift 50 million people out of poverty in a decade. An end to famine, a thriving African agricultural industry --- that's what opportunity looks like. That's what we want to build with you.

We believe that countries have to have the power to prevent illness and care for the sick. And our efforts to combat malaria and tropical illness can lead to an achievable goal: ending child and maternal deaths from preventable disease. Already, our commitment to fight HIV/AIDS has saved millions, and allows us to imagine what was once unthinkable: an AIDS-free generation.

And while America will continue to provide billions of dollars in support, we can't make progress without African partners. So I'm proud that by the end of my presidency, South Africa has determined it will be the first African country to fully manage its HIV care and treatment program. That's an enormous achievement. Healthy mothers and healthy children; strong public health systems -- that's what opportunity looks like.
