The 73rd Joseph Henry Lecture
Oceans and Human Health
A Symbiotic Relationship between People and the Sea
Rita R. Colwell
Retiring Director, National Science Foundation
About the Lecture
From the complex chemistry that spawned life on Earth to the many thousands of lives lost in surging seas, human fate has been hitched to the oceans. We have discovered that life in the oceans maintains the biogeochemical cycles necessary to sustain life on earth and that we share a mutual vulnerability to ecological change. We recognize that oceans are conduits for threats to human health but life in the oceans offers potential sources of therapeutic compounds which could be used to treat cancer and infectious diseases. Some of the ties that bind human health to the oceans, borrowing from my research on the relationship between infectious diseases and the oceans, will be highlighted, along with a look to the future, in which, using modern tools, we can reap a medical harvest from marine microorganisms.
