Threatened species are those that are in danger of extinction due to factors such as habitat loss, hunting, or pollution. These species are still around, but their populations are declining and they could become extinct in the future if the threats are not addressed.
There are several categories of threatened species, including:
* Critically endangered: These species are at the highest risk of extinction, with very few individuals remaining.
* Endangered: These species are in danger of extinction, but their populations are larger than critically endangered species.
* Vulnerable: These species are at risk of becoming endangered, but their populations are still relatively large.
Extinct Species
Extinct species are those that have completely disappeared from the Earth. These species no longer exist anywhere in the world, and they cannot be brought back.
There are many reasons why species become extinct, including:
* Habitat loss: This is the leading cause of extinction, as human activities such as deforestation and urbanization destroy the habitats of many species.
* Hunting: Hunting is another major cause of extinction, as humans have overhunted many species for food, fur, or other purposes.
* Pollution: Pollution can also lead to extinction, as it can poison the environment and make it difficult for species to survive.
The extinction of a species is a tragedy, as it represents the loss of a unique part of the natural world. It is important to take steps to protect threatened species and prevent them from becoming extinct.
