Every (Other) Breath You Take

Marine microbes are not as cute as sea otters, but they do produce about half the oxygen on the planet. Meaning you have microscopic marine microbes to thank for every other breath you take. And University of Washington oceanographer Ginger Armbrust just received a multi-million dollar grant to study marine microbial ecology from the Gordon and Betty Moore Foundation.

Ross Reynolds talks with Professor Armbrust about the latest science on the microbes that we can thank for every other breath.
