Watch: Why you should care about whale poo (6 mins).

Free TED Talk – Speaker: Asha de Vos

Focus: Whales / Duration: 6 minutes / Suitability: All ages

About: Whales have an important and surprising job, so says marine biologist Asha de Vos. These massive and magnificent mammals are ecosystem engineers. They are keeping the oceans stable and healthy by – in a word – ‘pooping’, and also by decaying after death, in their ‘whale fall’. De Vos, a TED Fellow, explains the undervalued work that whales do to help maintain our seas, and ultimately the planet. She is dedicated to increasing awareness about Northern Indian Ocean blue whales, and is committed to inspiring the next generation of marine biologists.
