Seafood lovers hooked on $1 oyster nights may soon have to find a new source of comfort for the work week blues.

Thanks to an increase of carbon in both the atmosphere and our water bodies (which absorb about a third of all carbon emissions), carbon munching critters like crabs, lobsters and shrimp are getting bigger and hungrier, say scientists at the University of North Carolina’s Aquarium Research Center. After analyzing blue crabs from the Chesapeake Bay in tanks pumped full of carbon, researchers found that the crabs grew nearly four times faster in high-carbon tanks versus low-carbon tanks.
 
Though bigger crabs sound like a delicious side effect of climate change, they’re not all that they’re cracked up to be, since crabs tend to put all their energy into building larger shells, not meatier flesh. Even worse, super-sized crabs with equally super-sized appetites could also affect the rest of the typical seafood platter, since bigger crabs will no doubt be eating bigger helpings of other seagoing creatures, like oysters.
 
Unfortunately, voracious crabs aren’t the only thing that oysters have to worry about. Because oceans are one of the world’s greatest carbon sinks, taking in 22 million tons of carbon dioxide every day, ocean chemistry is changing rapidly. This is putting a strain on shelled creatures like oysters, shellfish and corals that don't like acid baths because they depend on a pH-balanced lifestyle to build their calcium carbonate shells.
 

Power plant water discharges are filled with toxic pollution.  (EPA)

Coal-fired power plant pollution is contaminating our water, not just our air. Here’s how: when plants install scrubbers and other emission control devices onto smokestacks to capture air pollution, the chemical waste they pull from the air is then discharged into our waterways.

Not good.

This discharge contains mercury, arsenic, selenium and other toxic chemicals that can cause neurological and developmental damage, harm unborn fetuses in utero, damage internal organs, and cause cancer. Coal plants are the number one toxic discharger into our country’s waterways, yet the Environmental Protection Agrency has not reviewed clean water regulations for this industry in more than 30 years.

Until now.

McCarthy will be a vital player in the effort to protect our families and environment.  (EPA)

This week a Senate committee will hold a nomination hearing for Gina McCarthy to replace Environmental Protection Agency Administrator Lisa Jackson.

Gina McCarthy, the EPA assistant administrator for air and radiation, is a sound choice for the job. Given her background and experience, the Senate should move expeditiously to confirm her.

For more than 25 years Gina McCarthy worked with politicians from both parties, including a stint as Gov. Romney’s energy and climate advisor in Massachusetts. In 2009 Republican and Democratic senators easily confirmed McCarthy by a voice vote to head the clean air division of EPA.

Gina McCarthy is a dedicated environmental professional with a history of working on difficult issues including climate change. We share her vision of an energy-efficient economy which creates sustainable jobs.

The agriculture industry relies heavily on the use of pesticides, which are highly toxic chemicals that farmworkers and surrounding communities are frequently exposed to through simply doing their jobs or living near agricultural sites. Pesticides enter the body through inhalation and penetration of the skin. The latest statistics indicate that in 2007, 1.1 billion pounds of pesticides were used in the United States, and 80 percent were destined for agriculture. Among these, 33 million pounds were organophosphates, a particularly pernicious class of pesticides that are the most frequent culprits of acute poisonings of farmworkers.

Our nation’s farmworkers live and work at ground zero for pesticide exposure.  In a 1989 speech before Pacific Lutheran University, Cesar E. Chavez, a beloved labor and civil rights leader and an indefatigable voice for farmworkers, warned about the perils of pesticides and called on the nation to recognize the challenges that plague farmworkers, such as fighting for higher wages and improved working conditions. We’d be ignoring a greater evil if we failed to protect them from “systematic poisoning through the reckless use of agricultural toxics.”  In raising the urgency to protect farmworkers, their families and surrounding rural communities from pesticides, he shared stories of workers collapsing and dying after entering recently sprayed fields, children with birth defects and neurological problems and cancer. Meanwhile, workers were repeatedly told that the pesticides they were frequently exposed to were merely plant “medicine” they need not fear.
