The analogy I would make is a guy with a melanoma patch on his back walking down the street and getting hit by a bus.

Maybe that melanoma wouldn't have resolved itself. Maybe that melanoma would have gotten bigger. Maybe that melanoma would've turned into the tiny fraction that metastasize and actually kill the person.

But the guy was killed by a bus.

This issue is that stark in terms of assigning blame - the toxic algae outbreaks are 99.9% caused by the releases of the blooms on Lake O to the coasts.

You can watch it happen in real time with drones - the blooms on the lake are released and you can watch the bloom spread from the outflows day by day.
