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.
