There are many serious threats facing our oceans today. "Oceans’ Health: An Ecosystem on the Brink" explores two of these merging issues. First, ocean acidification: Over the last decade scientists have shown that human-caused increases in carbon dioxide (CO2) emissions are affecting the chemistry of our oceans, altering the main food web, and proving harmful for many forms of marine life. Second, commercial fishing: In recent years scientists have also estimated that the global supply of wild-caught seafood will run out by the year of 2048 unless stronger fishery management practices are implemented. Listen in to two leading marine scientists as they discuss these oceanic issues and what we as consumers can do to have a positive impact in addressing them.

This event features Allen LaPointe, vice president of environmental quality at the John G. Shedd Aquarium, and Kassia Perpich, sustainable seafood manager, also at the Shedd.
