So far, though, the president’s task force has been careful not to suggest that ocean zoning will be the only treatment plan, in great part because any effort to restrict commercial interests is bound to meet stiff opposition. “Zoning isn’t anybody’s favorite exercise,” notes John C. Ogden, director of the Florida Institute of Oceanography at the University of South Florida at Tampa. “Someone’s ox is always getting gored.” Most resistant to such change will most likely be the traditional users of the open ocean—namely, commercial fisheries and the petroleum industry. “They’ve had the place to themselves for a long time,” Ogden says.
Ogden and others are quick to point out, however, that zoning practices can benefit commerce as much as conservation. By giving up access to certain areas, industries gain the security of knowing their activities would be licensed in a more predictable and less costly manner than they are today, explains Josh Eagle, associate professor at the University of South Carolina School of Law. Now an oil company can apply for permits to drill virtually anywhere, but it takes on a significant financial risk each time. The business may dump millions of dollars into researching a new facility only to have a lawsuit derail it at the last moment. When opposing parties have more or less equal voices early in the planning process, Eagle says, they are less inclined to block one another’s activities once zones are drawn on a map.
Whether the final report of the president’s task force will promote ocean zoning explicitly is uncertain. But the group has already promised to overhaul the structure of ocean governance by proposing the creation of a National Ocean Council, whose job it will be to coordinate efforts of the myriad federal agencies now in charge.
The move comes just in time. Just as society is beginning to appreciate the enormous efforts it will take to preserve the health of the oceans, it must ask more of them—more energy, more food, and better resilience to coastal development and climate change. The reason the oceans are in trouble is not what people put in and take out. It is a failure of governments to manage these activities properly. Says Crowder: “We have to treat the oceans holistically, not one symptom at a time.”
The Power of Garbage
Trapped lightning could help zap trash and generate electricity
By John Pavlus
Trash is loaded with the energy trapped in its chemical bonds. Plasma gasification, a technology that has been in development for decades, could finally be ready to extract it.
In theory, the process is simple. Torches pass an electric current through a gas (often ordinary air) in a chamber to create a superheated plasma—an ionized gas with a temperature upward of 7,000 degrees Celsius, hotter than the surface of the sun. When this occurs naturally we call it lightning, and plasma gasification is literally lightning in a bottle: the plasma’s tremendous heat dissociates the molecular bonds of any garbage placed inside the chamber, converting organic compounds into syngas (a combination of carbon monoxide and hydrogen) and trapping everything else in an inert vitreous solid called slag. The syngas can be used as fuel in a turbine to generate electricity. It can also be used to create ethanol, methanol and biodiesel. The slag can be processed into materials suitable for use in construction.
In practice, the gasification idea has been unable to compete economically with traditional municipal waste processing. But the maturing technology has been coming down in cost, while energy prices have been on the rise. Now “the curves are finally crossing—it’s becoming cheaper to take the trash to a plasma plant than it is to dump it in a landfill,” says Louis Circeo, director of Plasma Research at the Georgia Tech Research Institute. Earlier this summer garbage-disposal giant Waste Management partnered with InEnTec, an Oregon-based start-up, to begin commercializing the latter’s plasma-gasification processes. And major pilot plants capable of processing 1,000 daily tons of trash or more are under development in Florida, Louisiana and California.
