@T3Deliciouz @Gammatelier Well, this is fairly old. The idea that there are ways of controlling pests without pesticides was not mainstream in the first world at the time. So, if the problem is too much pesticides (not to mention herbicides), just not using them wouldn't have seemed realistic. That leaves "responsible use" . . . which was never going to happen and has receded ever further since then, especially on the herbicide front, with the main genetic modification on GM crops being resistance to herbicides so they can spray three times as much.
Also, back then nobody had yet noticed that bees are insects, because they hadn't yet started dying en masse . . .
