Recently my students have remarked how clean Japan seems to be (as a first impression) yet also expressed confusion/frustration about the lack of trash cans in public. Here's some more garbage news about Japan from MSNBC:
Japan's space agency is reportedly teaming up with a fishing net manufacturer to catch and remove debris from Earth orbit, where it poses a threat to spacecraft, astronauts and satellites.
The space fishing net would span several kilometers and be made of thin metal wires. As it scoops up space debris, it will be charged with electricity, allowing Earth's magnetic field to reel in the haul and eventually burn it up in Earth's atmosphere...
