Stephen Palumbi: Following the mercury trail
In another TED Talk from the Mission Blue Voyage, Marine Biologist Stephen Palumbi talks about biomagnification – how mercury from the bottom of the ocean food chain makes its way up into the human body, with terrible results.
With a close link to recent HPD topics on the environment’s link to health and to G3: Impacts of Humans on Ecosystems, Palumbi highlights the tight connection between the oceans and our own health as humans.It might better be entitled “Protecting the Ocean Pyramid,” or “Beach closed due to excess human fecal matter.“
Impacts of Humans on Ecosystems
For Option G: Ecology and Conservation. Because we’re learning this concurrently with the Ecology and Evolution core topic, the Essential Biology document has been rolled into one: Essential Biology 5.2 & G3 – Greenhouse Effect and Impacts of Humans on Ecosystems.
The presentation on The Greenhouse Effect will follow soon.
