@hawaii_jake That’s really interesting. According to the Wikipedia article some would consider that it starts with the beginning of agriculture and aanimal husbandry as human tools to control food supplies. I would tend to agree with that, and divide the Anthropocene Age into two parte: Early Anthropocene, (Agricultural) Era (from approimately 6000 BCE, with the development of agriculture), and the Later, or Current Anthropocene (Industrial) Era, about 1300 CE, with the invention of timepieces that operate independently of natural cycles
