“While the sun supplies much of the energy for normal agriculture, growing hydroponic crops year-round could be an energy glutton”
They do not have to be year round, not all crops need the same amount of light (tomatoes do need allot) . . it SAVE energy and money from having to import them in the winter months . .etc . . so we have a full spectrum of good to poor ..

“good soil now buried beneath glass and concrete, and any archaeologists who many have wanted to excavate the historical area are out of luck.”
This has to be a joke argument. . as archaeologists have a problem with ALL development . . (also these green houses do not require a concrete floor . .thick plastic tarps work just as well . .as shown)

“foodies aren’t terribly happy “
Well? They are terribly happy about much anyway so what is the deal? Imported food often has to be picked while still unripe . . this does have a effect on taste and texture . . while “terroir” is much much more subtle and often non existent in some foods (so winter is still a problem for foodies regardless) . . Also some of the cause and effects of “terroir” are being discovered and should be reproducible (much to there horror ) . .

“pathogens”
Some will be easier some will be harder to control . (ie risk from fertilizer derived from dung is eliminated but contamination from tools, water, or workers’ clothing is no different from traditional and the current problems). but the biggest problem IS the mass production since that is were it can to the most harm (mass contamination rather then small lots of contamination). . . if hydroponic greenhouses are kept as “smaller” separate units . . and they all most have to be since single massive greenhouses are problematic . .then contamination can be minimized if found. So in the end it should be about equal or possibly better.

All in all this should be a good supplement to current importing . . . . and rather poor arguments to date against it.
