Recent transformations have accelerated that impact, but in fact it stretches back to the earliest days in human history. In his new book The Last Animal: Human History and the Fate of Life on Earth from the Ice Age to the Sixth Extinction, historian Kyle Harper traces how humans have impacted the rest of the planet, from extinction events to much more subtle changes.
