A third case will be mentioned here, albeit briefly. If under very particular external influences good high-spring water is rotated at high speed in turbines with blades inclined at a certain angle, then on occasion the effective force rises exceptionally high; by calculation to peak pressures of about 32,000 atmospheres, leading to corrosive damage to the turbine blades. More detailed elaboration would take too long here, and therefore it should be enough to point out that these three phenomena are known facts.

"Think about oxygen. Necessary for life now, but oxygen is actually a metabolic poison, a corrosive gas, like fluorine. When oxygen was first produced as a waste product by certain plant cells some three billion years ago, it created a crisis for all other life on earth. Those plants were polluting the environment, exhaling a lethal gas. Earth eventually had an atmosphere incompatible with life. Nevertheless, life on earth took care of itself." [Michael Crichton]
