A new study released this month models what happen to the health of the planet when giant plants and animal vanish. It’s happened before—at the end of the last Ice Age when mammoths and enormous sloths died out. Humans likely played a part in that extinction and the researchers say Earth’s big animals today are headed for the same fate because of overhunting, habitat loss, climate change and other factors. KNAU’s Melissa Sevigny spoke with Northern Arizona University’s Andrew Abraham who was one of the authors of the study.
