Except this proposal is widely accepted in the scientific community with hundreds of ecological studies behind it, where as the Four Pests was just speculation by a guy who likely never studied any modern biology.
What i was using this example for, however, was the unpredictability of influencing an infinitely interconnected and complex system. In the case of the four pests, the influence was crude and especially myopic, so it makes for a wonderful example.
It is rare that the influence ends where we imagine it would. There are many possibilities for race conditions which i know i can’t even imagine.
