Earlier this week, Jason told you about a TEDx talk in which 19-year-old Boyan Slat presents a plan to remove plastic from the world's oceans
. Lots of people are excited about this, which is reasonable. Particulate plastic in the ocean is a big problem that has, thus far, evaded any reasonable clean-up plans. There's just so much of it, it's so tiny, and the ocean is, you know, kind of huge. If a kid can come up with a plan that works, it would be fantastic. Unfortunately, the ocean scientists at Deep Sea News say Slat's system isn't as simple and practical as he thinks it is
. Among the many problems: Slat's plan would catch (and kill) as many vitally important plankton as pieces of plastic, and it calls for mooring plastic-collecting ships in the open ocean where the water is 2000 meters deeper than the deepest mooring ever recorded. Here's a mantra to remember: TED Talks — interesting if true.
