Another good S.F. Bay Area clean-up idea: Use Hunter's Point in S.E. San Francisco (a WW2 Navy toxic site,,,still) to clean-up the Delta Mothball ,,,

,,,Fleet(sloughing tons of toxic paint into the Bay,for decades,,,). Then, once all those old ,useless metal ships are cut up by the local unemployed with cutting torches for scrap and loaded on a train for a smelter, you can finally clean up the eyesore and toxic Hunter's Point !!
