Lakes near an active volcano, once it erupts, can lead to the lake being oxygen deprived. Inspired by the latest Post by Vince Summers
I just read an article by Vince Summers: link provided below:
And it inspired me to write this article about the possibility of oxygen deprived water to make possible the existence of certain forms of bacteria, perhaps on other planets with high concentrations from erupting volcanoes in their respective emerging and developing planets that would put them in the state of early Earth, when it too was in a state of constant volcanic activity and heavy bombardment from asteroids, meteors and comets, several billions of years ago.
Think about lakes on Mars or Venus.
Large bodies of water surrounding land masses that frequently erupt with volcanoes that spurt out tons of fall out from their explosive interiors.
There might be advantages to oxygen deprived lakes?
If the lake near where an eruption of a volcano that took place in the 1980s when Mt. Saint Helen's caused Spirit Lake to become prime breeding ground for a bacteria that can become fatal to humans when droplets are inhaled. But this fails to put into perspective that early Earth had no life on it yet and any planet that can produce complex microbes must first have several species of life that can co-exist in that period to create the effect of being made ill by exposure.
If for instance an alien world with water and heavy volcanic activity could in fact create bacteria on a world that had no higher or more complex life yet, maybe the earlier forms of life like the single celled protozoa of ancient Earth when the atmosphere was in fact not conducive to life as we currently understand it but when single celled life formed, maybe there is some type of condition on waterworlds for bacteria to evolve into higher forms of bacteria? Just a thought.
