Taped by WGBH Forum Network, biologist Robinson "Wally" Fulweiler visited the New England Aquarium to discuss the immortal life of nitrogen.

Fulweiler talks about how you can reduce your own nitrogen footprint - and why it's just as important as carbon.  She also explains where nitrogen comes from and why it's so important to have just the right amount on earth.

This talk was taped on June 3, 2014 at 7:00 p.m.
