Something as simple as better breastfeeding could save a million children a year.
When parents are confident that their children will live, they have fewer of them. They invest more in each child's food, health and education.
Whenever an earthquake or tsunami takes thousands of innocent lives, a shocked world talks of little else. I'll never forget the wrenching days I spent in Haiti last year for Save the Children just weeks after the earthquake.
If we could muster the same determination and sense of responsibility that saves a country like Japan - or a company like Xerox - then investing to save women and children who are dying in the developing world would be very good business.
