When the world started switching to LED-based traffic lights, cold places suddenly discovered that there was a problem: they would get covered in snow. Turns out that the old incandescent ones had a solution to this problem in giving off heat. As trivial as it is once you think about it, it was a problem that we didn't even realize we had solved. I always use this as an example of how bad we are at predicting the outcome of our actions. It's why small iterations make so much sense. For running your company and for anything. Eradicating mosquitoes might seem harmless in any way we can think of (even though the article gives good examples of why it probably isn't), but even so, such a massive change in the eco-system is bound to have a bunch of really severe consequences that we hadn't foreseen.
