Поллан про картошку (The Botany of Desire)

Поллан пишет -- в почве живут бактерии Bacillus thuringiensis (Bt), которые вырабатывают яд, смертельный для Leptinotarsa decemlineata, колорадского жука, известного картофельного вредителя. Этот яд с 1920-х гг. используется в сельском хозяйстве как пестицид.

Сумрачный миссурийский гений (фирма Монсанто) смог внедрить ген, отвечающий у бактерий за выработку этого яда, в ДНА картофеля, и получить не требующую опрыскивания картошку, вырабатывающую пестицид на листьях самостоятельно. Сорт называется NewLeaf.

Поллан вырастил на своем огороде (почему русские так любят дачи? ведь картошку можно купить в магазине. почему русские так любят дачи? ведь картошку можно купить в магазине. почему русские так любят дачи? ведь картошку можно купить в магазине) вырастил у себя на огороде мешочек такой картошки, для смеха, а потом стал думать, выбросить ее, или съесть.
     There was this too: I'd called some of the government agencies in Washington that had signed off on the NewLeaf, and what they said didn't exactly fill me with confidence. The Food and Drug Administration told me that, because it operates on the assumption that genetically modified plants are "substantially equivalent" to ordinary plants, the regulation of these foods has been voluntary since 1992. Only if Monsanto feels there is a safety concern is it required to consult with the agency about its NewLeafs. I'd always assumed the FDA had tested the new potato, maybe fed a bunch of them to rats, but it turned out this was not the case. In fact, the Food and Drug Administration doesn't even officially regard the NewLeaf as a food. What? It seems that since the potato contains Bt, it is, at least in the eyes of the federal government, not a food at all but a pesticide, putting it under the jurisdiction of the Environmental Protection Agency. Feeling a bit like Alice in a bureaucratic wonderland, I phoned the EPA to ask about my potatoes. As the EPA sees it, Bt has always been a safe pesticide, the potato has always been a safe food, so put the two together and you've got something that should be safe both to eat and to kill bugs with. Evidently the machine metaphor has won the day in Washington too: the NewLeaf is simply the sum of its parts—a safe gene added to a safe potato.
