Microbes Rule the World
Microbes make up 80 percent of all biomass, says microbiologist Carl Woese. In one-fifth of a teaspoon of seawater, there are a million bacteria (and 10 million viruses), Craig Venter says, adding, “If you don’t like bacteria, you’re on the wrong planet. This is the planet of the bacteria.” That means that most of the planet’s living metabolism is microbial. When James Lovelock was trying to figure out where the gases come from that make the Earth’s atmosphere such an artifact of ...Stewart Brand describes the state of our world, engineered by microbes and ourselves as the vehicles for their propagation in many cases.

1945 Warning of Bacterial Antibiotic Resistance
But I would like to sound one note of warning. Penicillin is to all intents
and purposes non-poisonous so there is no need to worry about giving an overdose and poisoning the patient. There may be a danger, though, in
underdosage. It is not difficult to make microbes resistant to penicillin in the
laboratory by exposing them to concentrations not sufficient to kill them,
and the same thing has occasionally happened in the body.
The time may come when penicillin can be bought by anyone in the...At his Nobel lecture for discovering penicillin, Alexander Fleming warns that if you use, use enough to kill. Maiming the bacteria will make it resistant.
