What the Oceans are Telling Us

This talk analyzes how human impacts on the world's oceans have devastated populations, species and ecosystems at a rapid scale, and how methodologies to assess marine ecosystem health are grossly lacking. Conservation medicine is an emerging scientific field helping us learn to listen to what the ocean is telling us and providing new approaches to conservation. This field finds links between human-induced and natural changes in climate and habitats; the emergence of pathogens, parasites and pollutants; the biodiversity and health in animal communities; and health of humans.There is growing evidence that marine ecosystems are increasingly threatened. Oceanographers are documenting changes in ocean temperatures that relate to global climate change. The world coastal zones face enormous human developmental and urbanization pressures. Some symptoms of human impacts on the marine environment include increased frequency and intensity of harmful algal blooms, increased stress on species as a result of overfishing, loss of breeding/nursery habitats, and the spread of persistent chemical pollutants such as dioxins and PCBs. Many populations of marine mammals, marine birds and sea turtles are exposed to pollutants from agricultural runoff, human sewage, and pathogens with a terrestrial origin. Unprecedented numbers of diseases linked to large-scale marine mammal deaths have been documented recently.
