The Microbes In and Around Us - Nathan Wolfe

Microbes that we can't see affect so many things that we can see, feel - both by touch, as well as inside of ourselves. Emerging Explorer Nathan Wolfe tells Boyd that with every breath, we inhale living microbes that could be completely benign, or could cause a life-threatening illness. The microbes could be from Africa or Asia, just as easily as they could originate very close to us. Wolfe says that's what keeps him exploring - the possibility that the next big discovery could be floating in front of his face. His article "Small, Small World" appears in the January, 2013 issue of National Geographic magazine.
