Are we at fault for handing them out without proper education? Do they know that these nets are laced with poison? I mean if it only hurt the people who are fishing, maybe I could live with it but it hurts everyone (kind of makes me think of second hand smoke but worse).

Something they didn't bring up in the video is that a lot of fish (the net is indiscriminate) can help keep mosquito population in check. Just another thing to pile on the list.

Maybe we need to stop sending nets treating with toxic chemicals to that part of the world. This just looks like a road paved with good intentions.

No, it's a sensible trade off.

Go look up pyrethroid insecticides and malaria and then contemplate whether you'd rather risk sleeping in a treated net all the time or be sickened at length or maybe dead.

Mosquito nets make poor fishing nets. Maybe a few fishermen have tried, failed, and passed that bit of knowledge along to other fishermen.

For the same reason no one uses rubbing alcohol in an automobile. Technically it's a hydrocarbon but using it in a ICE will lead to poor results.
