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.
Scientists generally agree that the reason for any mass extinction can be traced to a variety of environmental factors that may have resulted from a triggering event. The extinction that occurred at the end of the Permian period, 250 million years ago, was probably the most severe in Earth's history.
