A day or two ago there was a thread on FR about the recent banning of Microbeads. This led me to reading about pumice. Pumice is formed by lava that had air bubbling up through it. It is filled with open cavities, I suppose like Swiss cheese, or a sponge. Anyway, it floats. Giant rafts of pumice are adrift, to this day, in our oceans. They have been a means of transportation for plants and animals from one continent to another. I suppose the Mayans may have run into pumice (lava) washing up on their beaches. Evidently, there was intercontinental swapping even before “man”.
Microbeads are probably responsible for colony collapse disorder. :’)
