Human-induced species extinctions are not confined to the Anthropocene. Since humans evolved into a dominant predatory species, their actions have influenced the extinction of other species. Evidence suggests that the Quaternary Megafauna Extinction, spanning 52,000–9,000 BCE, was driven by early humans
The author argues that "human-induced species extinctions" are not just a result of modern fossil fuel and environmental practices, but from hunting ever since humans became a dominant species. Humans have greatly effected the environment for much longer than many give credit for. Environmental damage doesn't necessarily come from burning fossil fuels, it seems to increase when humans make social and technological advancements.
