As Amanda Maxham writes for the Ayn Rand Institute, some anti-GMO activists have called for the murder of scientists who conduct, and of writers who support, genetic engineering of plants. Maxham also discusses environmentalists who advocate population control. In a 2012 interview with me for the Objective Standard, Robert Zubrin aptly characterizes such environmentalist attitudes as a “scourge of antihumanism.” And recently I discussed an environmentalist plan to engineer humans as a way to reduce their “carbon footprints.” So, for environmentalists, apparently it’s not okay to engineer food for human benefit, but it is okay to engineer human beings for the sake of the “environment.”
