This past Halloween, the world's population hit seven billion, according to the United Nations. So what do we know about our planet's seven billionth child? And what world will he or she grow up in? A few days before this landmark, Suzanne Petroni the vice president for global health at the Public Health Institute, came on The Takeaway to discuss these questions — and she had some surprising predictions on who the Earth's seven billionth person would be.

The world’s population is set to reach seven billion on Monday, October 31, 2011. The Takeaway is talking about what this monumental number means for people, resources and the planet. One of the biggest questions is who exactly the seven billionth person will be and what his or her life will be like. Suzanne Petroni is vice president for global health at the Public Health Institute, and she has some surprising predictions on who this person might be.
