I read once that ironically one of the most important ecological niches for mosquitos is that they keep humans out of a bunch of places that allow those habitats to be preserved. It’s their annoyance and medical danger to people that makes them so valuable to the ecosystem.
The algorithm is clever enough to know that people that watch a few of those videos are likely to watch a whole lot more. So it’s good business to recommend them as often as possible. If they CAN convince you to dive into that, the stats are that you will start to watch a ton more YouTube content.
