Going down instead of up? An upside down pyramid building, or "Earthscraper," has become something of an architectural sensation, but its green credits are dubious. Other ideas based on the same concept try to account for earthquakes, ventilation and sunlight.

We also have landmines as an unexpected tool for land preservation, bacteria-powered lighting, a giant protest of nuclear power in Germany, a huge pile of tires visible from air possibly sending someone to prison, and more in our roundup of the best images on TreeHugger this week.
