There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption.
Through the activity, students will create a list of reasons why animals can become extinct.
What are the main causes of extinction?
Humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. Explosive, unsustainable human population growth is an essential cause of the extinction crisis.
What are the 5 mass extinction?
These five major mass extinction events include the Ordovician Mass Extinction, Devonian Mass Extinction, Permian Mass Extinction, Triassic-Jurassic Mass Extinction, and Cretaceous-Tertiary (or the K-T) Mass Extinction.
What are the common causes for the extinction of plants and animals?
Deforestation and urbanization combine to create two reasons why plants and animals become extinct. Deforestation is leveling forests to harvest the wood or create space for building or agriculture, while urbanization is the turning of once-rural areas into cities.
How do humans cause extinction?
Human activities that influence the extinction and endangerment of wild species fall into a number of categories: (1) unsustainable hunting and harvesting that cause mortality at rates that exceed recruitment of new individuals, (2) land use practices like deforestation, urban and suburban development, agricultural
