How Do We Sustain a World of 7 Billion People? Live Stream, March 27, 4:00 to 5:30 P.M. ET

Sylvia Earle and other experts brainstorm ways to make the planet more sustainable and secure

The world population currently stands at about 7 billion people, and the United Nations expects that to grow to 9 or 10 billion by the end of the century. But populations generally don't stay at the same level for long periods of time--they tend to cycle up and down, and sometimes, if they've grown in ways that are unsustainable, they crash. How do we avoid this fate and keep the world on a sustainable path?

This question is being put to a panel of experts at the Affordable World Security Conference in Washington, D.C. on March 27. Led by cientific American executive editor Fred Guterl, author of the forthcoming book Fate of the Species (Bloomsbury). Panelists include:

WOLFGANG LUTZ, founding director of the Wittgenstein Center for Demography and Global Human Capital in Vienna, Austria.  People often look at population simply as so many mouths to feed, but Lutz focuses in his work on how people can be engines of growth and change.
