Aphanizomenon. Is this a phenomenon
In the United States?
Cylindrospermopsin. Is it a toxin
Of common occurrence and fates?
But half of your lakes
Have got what it takes
To lead any national list in
Producing that hazardous microcystin.
To avoid liver harm and neuro-paralysis
We have all been told to do good analysis.
We also now know that both you and me
Need to advocate cutbacks of N and of P.
