Fish-Eating Bird Disrupting Food Chain?

The once near-extinct double-crested cormorant has made a dramatic
comeback in the past few decades, and sport fisherman say the
fish-eating birds are hurting their business. But as states move to
limit their cormorant populations, there’s still no solid research that
the birds are really to blame. The GLRC’s Gregory Warner reports:


More states are joining the war on cormorants: oiling eggs to prevent
them from hatching, or shooting the birds. More than 11,000 of the
federally-protected birds were shot last year.


But there’s still no scientific proof saying birds compete with sports
fisheries. Jim Farquar is a biologist with the New York Department of
Conservation:


“We’ve not been able to detect declines in the fisheries at this point
in time. But that doesn’t mean that with a larger cormorant population
it won’t happen.”


At issue is diet. Cormorants eat whatever small fish are available,
leaving big game fish alone. In some regions, the birds eat almost
exclusively round gobies, an invasive species. Anglers believe that
cormorants disrupt the food chain, causing the numbers of larger fish to
decline.

States Sue Epa Over Mercury Contamination

The EPA recently finalized its mercury reduction plan for coal-burning power plants. Mercury is a neurotoxin that can damage developing children. Now 16 states are taking the EPA to court, saying the so-called “cap-and-trade” plan doesn’t go far enough. The GLRC’s Gregory Warner reports:

The EPA recently finalized its mercury reduction plan for coal-burning power
plants. Mercury is a neurotoxin that can damage developing children. Now
16 states are taking the EPA to court saying
the so-called “cap-and-trade” plan doesn’t go far enough. The GLRC’s
Gregory Warner reports:


The coalition of states filed the suit in the U.S. Court of Appeals for the
DC Circuit, challenging the cap-and-trade rule.


Cap-and-trade allows operators of older power plants to swap pollution
credits with newer plants instead of minimizing their own emissions.


EPA regulators say their program will cut mercury pollution by 70 percent over the
next 12 years. The states say mercury is too dangerous for a go-slow
approach. Emily Green is with the Sierra Club:


“Just a little bit can cause major problems for children’s health in
particular, so right now we have the technology to reduce mercury from coal
plants by 90 percent, that’s what we should do.”


In contrast to the EPA rule, more than 20 states have adopted or are moving
to adopt more stringent rules to reduce mercury emissions.
