Human impacts. Most of the main causes of extinction are caused directly or indirectly by humans. Humans negatively impact the environment for controlling and artificially causing fires, shifting agriculture cultivation with unsustainable techniques, grazing by domesticated animals, overkilling species (Pleistocene overkill), etc.
In the popular mind, mass extinctions are associated with catastrophic events, like giant meteorite impacts and volcanic super-eruptions. But the worldâs first known mass extinction, which took place about 540 million years ago, now appears to have had a more subtle cause: evolution itself. âPeople have been slow to recognize that biological organisms can also drive mass extinction,â said Simon Darroch, assistant professor of earth and environmental sciences at Vanderbilt University.
