If evolution has taught me anything there will be probably be a section of the population who will become tolerant to microplastics. Perhaps already started. Also, perhaps those who are accumulating the most, who will come to evolve with it, are showing signs of low IQ /cognitive decline. As a result, they reinforce the accumulation of microplastics via lifestyle/decisions, further propagating the cycle. Hmm, perhaps this explains Trump and his supporters. Sorry, hate to make this political, but I couldn’t help myself. This would explain though our continued decline into Idiocracy.
