Sufficient food makes algae spread,
no matter if blue, green or red.
Some are as poisonous as lead,
So we take care not to be dead.
If nature dies we will be sad
and cannot grow the wheat for bread,
which not alone is really bad,
can’t be replaced by rye instead.
Thus what we deem as contribution
to our life can be a danger,
because it furthers the pollution,
makes living space hostile and stranger.
