Watch Marie’s (unedited) TED talk, given at the first TED-South conference in Latin America. The conference was in Rio de Janeiro in a fabulous tent set up on Copacabana Beach. Usually, TED talks are edited to a fine, polished product, and all the uhms, ahs, and slips removed, but here you get to see my performance in the raw. The Rio conference was a wonderful experience! So many talented, inspiring, and ambitious minds under the tarp.
