Hans Rosling at TED: "Child survival is the new green"


A TED Favorite, Worth Watching
Hans Rosling, the Swedish expert on world population trends and probably the person who has been invited the most times to speak at TED in recent years, gave a great talk that looks at world population trends in the past 50 years and in the next 40. During the talk, he makes an excellent point that is worth highlighting here It's a bit counter-intuitive, but if more children survive in poorer countries (where they currently have high child mortality rates), world population will stabilize. At first glance, it might look like lower child mortality would lead to big family, but it's actually the other way around. People have big families because they don't know how many children will survive. In all other countries with very low child mortality, as well as education and better economic opportunities, family size is barely at the replacement rate, if not lower. Hence "Child survival is the new green". See also: This Device Provides Clean Water for Pennies a Day
