I love these, they're great entertainment. A nice rehearsal of most of the ways that we're fouling our nest - resource depletion (especially high-quality sand)

I love these, they're great entertainment. A nice rehearsal of most of the ways that we're fouling our nest - resource depletion (especially high-quality sand), topsoil destruction, groundwater depletion, bio-diversity loss (under which is included fishery destruction) and increasing debilitation of governments in many parts of the world. You kids are going to be living in interesting times.
