I am often asked why we can’t vacuum up the particles. In fact, it would be more difficult than vacuuming up every square inch of the entire United States, it’s larger and the fragments are mixed below the surface down to at least 30 meters. Also, untold numbers of organisms would be destroyed in the process.His 2009 TED Talk is also worth watching.
