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.
A species is extinct when all of its members have died. Human actions have caused many species extinctions, including the great auk, the passenger pigeon, the dodo, the Monteverde golden toad, the Chinese paddlefish, and the Bali tiger. Biologists try to avoid future extinctions by learning how the species above went extinct and by monitoring groups that are currently threatened.
