These micro-micro creatures are at the limit of my microscope's imaging capacity so I strain to focus on them and understand what they really look like.

Nice. It was cyanobacteria that began producing a gas that killed most life on earth. That gas was oxygen, so we have a lot to thank them for.

True; those anaerobic oxygen producers also show us humans aren't the first specie to exterminate others (and themselves) via their own waste products. Of course a population of yeast in a vat of sugar water do the same thing all the time but in that case, we humans look forward to consuming the waste product that caused their extinction...alcohol.
Don, I did a look and remembered being a water chemist for the city of Detroit and all the little guys in the water, most dead, but in the mains living nematodes were too common. At that time, 1960, the maintenance people would pull out a Cyprus wood water mains. They were joined with cast iron rings sharp at each end being coupled with man swung sledgehammers. Well over 100 years.
My short stay in Guatemala in a local people's hotel, I was puzzled by the pitcher of cloudy water with sediment in the bathroom. Oops it was purified, the tap water was not. The water mains were often damaged by the frequent earthquakes and when they were shut down groundwater infiltrated.
