TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds. Since then its scope has become ever broader. The annual conference now brings together the world’s most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes).
This site makes the best talks and performances from TED available to the public, for free. This link is to a short talk (21 minutes) that has all the best aspects of Physical Geography/Biogeography/Cultural research plus a compassion for the world and all its inhabitants at its heart. It really is worth the 21 minutes to become inspired by great work..
