Mulch ado about nothing?...Or the "Sand Witch?"

Unique nanotechnology products and processes are entering large-scale use in the environment without regulatory oversight. Materials and processes approved at conventional scales (macro or micro) do not require re-examination when used at the nanoscale even though the impact on the ecosystem – including on biodiversity – could be radically different. A recent event on First Nations’ land in New Mexico using what appears to be a nanotech self-assembly process should be a warning to government and industry.
