data from 37 experiments conducted around the world. Together, these tested the impacts of 31 different pesticides on the social behaviour of 11 different fish species.
The evidence suggests pesticides make fish less social, and this finding is consistent across species. Courtship was the most severely impacted behaviour — the process fish use to find and attract mates. This is particularly alarming because successful courtship is essential for healthy fish populations and ecosystem stability.

I really don’t think I need to say much more. The article says all it needs to.
I guess one more point would be useful.
Long before pesticides reach lethal doses, they can disrupt hormones, impair brain function and change fish behaviour. Many of these behaviours are essential for healthy ecosystems.
Terrestrial ecosystems are impacted as well. Some are affected to a far greater extent because the toxins are not diluted. And if an animal rubs against them it must then lick it off it’s fur or feathers and ingest them.
If our “environmental organizations” are not actively and aggressively combating the current overuse of pesticides they are part of our problem, not the solution, and they are not the “environmental organizations” they claim to be.
