Another Thing to Worry About as the Planet Moves Further Into Its Anthropocene Era?

The term 'Anthropocene' has been proposed for the current geological era, when humans are clearly the dominant influence on the planet's environments. Scientists are now claiming that chemical pollution has now crossed a 'planetary boundary'. A boundary is a point at which human-mediated changes to the Earth, push its ecosystems outside the stable arrangements, that have persisted for the last 10,000 years. Humans depend on these ecosystems for their continued existence (https://www.theguardian.com/environment/2022/jan/18/chemical-pollution-has-passed-safe-limit-for-humanity-say-scientists). The scientists have looked at the environmental impacts of 350,000 synthetic chemicals. The most concerning are plastics, pesticides, antibiotics and polychlorinated biphenyls (PCBs). PCBs are colourless, odourless chemicals, much used in electrical equipment. They are very resistant to change. So the 'climate crisis' isn't our only problem. You can't say, however, that humans (for now?) don't pack a punch!
