I’ve made mention of the garbage island out in the North Pacific before. In what isn’t a big surprise, there’s a comparable assemblage of refuse in the North Atlantic. Wired Science has the details, including a computer model that appears to suggest that comparable gatherings of trash might be found in the southern regions of both the Atlantic and Pacific, as well as the southern Indian Ocean. That’s based on measurements of ocean currents. Science has the full study (abstract only, subscription required for full paper). It should be noted that most of the debris is composed of individual particles too small to be easily detected by sight, requiring the researchers to measure by using nets.
Of some interest is the observation that the Atlantic patch has remained relatively stable over the last 22 years. At the same time there has been a dramatic increase in the production (and discarding) of plastic. There are many possible explanations from that, including the possibility that the trash eventually sinks.
While I’d love to see these patches disappear, I recognize the cleanup process could cause as much disruption as it might disperse. Getting at these patches will probably require greater emphasis on reducing how much of this stuff gets thrown out and discarded in ways that reach rivers, streams, and then the ocean.
Generally speaking, the U.S. Congress is not a fan of peer-to-peer (P2P) file sharing systems. There are at least two bills in the current Congress aiming to regulate the use of P2P software, and congressional hearings on the subject raise all sorts of concerns about the security of the programs. There’s also a ban on using P2P applications behind the House and Senate firewalls. At least some of this concern stems from the very energized entertainment lobbies who see P2P programs as a vehicle for intellectual property pirates angling to swipe movies and music (hearings on those P2P bills usually mention the theft of intellectual property). While that is certainly a legitimate concern, it manages to crowd out the beneficial programs that are P2P.
One such program is the P2P-based program Skype, which allows for phone and video transmission over the internet. You have probably seen it used on some newscasts when anchors are trying to speak with a person at another location where they don’t have a television camera. Some members of Congress would love to use the program (H/T SEFORA) instead of renting more expensive videoconferencing equipment, but are running up against the ban. While it’s great that the House and Senate are taking steps to make sure their networks are secure, the failure to distinguish between beneficial and harmful uses of P2P networks is as much to blame for the difficulties in adopting Skype. It’s an indirect causation, as it’s the image in Congress of P2P as bad that has contributed to the problem, not a concern for protecting intellectual property (that’s what prompted the image of P2P).
