Climate change brings warmer conditions in waterways, and often less waterflow, which increases algal blooms.
The link between algal blooms and associated neurotoxins and ALS is acknowledged, likely from an amino acid called BMAA.
Studies have shown clusters of ALS (motor neurone disease) around affected lakes and rivers. One such incidence is Australia's Murray/Darling River, which has suffered severe algal blooms.

The point of this post? Be aware - source clean drinking water, don't swim in algae-affected waterways, and avoid other contact with affected water. It appears some people are more susceptible to the problem than others, thanks to the genetic lottery.
