Like most other extinctions caused my Human kind, none of such is more comedic than their own demise. Before the Glaciocene (one of the ages before the Xenocene), Man kind was being pushed into a set a events that lead to their own extinction, before without thought or control, they were wiped out. A Disease called "Citarum Virus" Originated in the Citarum River, Indonesia; so called the Dirtiest river of 2020. The Disease began to spread quickly since it was so close to humans and spread by the water which much of the cities, smaller towns and big industries sat on. The Disease's Symptoms were a slight cough, heavy headaches and weak knees just to name a few, these among with the many domesticated animals it affected stood no chance as it covered the whole planet with in mere months. Much like the deadly disease before, Covid 19 that lasted from 2019-2022 the Citarum virus spread at the rapid rate and and lasted for 20 years. Unlike other diseases before it, the deadly Virus chose a number of species to affect, this included many domesticated animals. Causing not just humans to die off but an array of species man had domesticated. Cats and Dogs suffered the Most from this and died along side man around the same time; Cattle, rodents, canids, felines, goat, sheep, birds, waterfowls, pigs and Camels also suffered heavily; some groups even vanishing completely. But from these extinctions gave rise to new groups that Exploded at the Start of the Glaciocene (about 800,000 MYF). (more Xenocene lore on the way)
