A sustainable world means working together to create prosperity for all.

Human beings tend not to spend money on health preventionally. We tend to spend it on top treatment.

I've heard it said that the most dangerous animal on the planet is the adolescent male.

Traditional charity and aid are never going to solve the problems of poverty.

The human spirit is extraordinary. If we give the 3 billion people who live in poverty the opportunity to change their lives, they will. For too long, we've looked at needing to "save" these people - with an emphasis on "these people" - rather than removing the constraints keeping them from solving their own problems.
