The picture I took shows a pond with a sign sticking out of it. The sign simply says:
What on earth does that mean? Will this Blue Green Algae rise up from the depths and grab us by the ankles to drag us off to the deep?
Perhaps it just means we have a slip hazard — that blue green algae is slippery. Thing is, I could not see anything slippery on the paths.
What the devil is Blue Green Algae? Is it a dust? a liquid? A winged serpent? What ought I be looking out for? Will it fall from the trees? will it run after us? Is it blue or green — or blue-green — or do they mean it is both blue and green (that both the blue and the green varieties are dangerous)?
Yes, things are getting worse when signs strike fear into English-speaking passers-by.
