Endangered species are organisms that are likely to disappear from the surface of the earth. This means that they are at risk of becoming extinct in the wild due to a variety of factors, including habitat loss, climate change, poaching, and pollution. Endangered species are not likely to migrate to other favourable lands because their habitats are typically already fragmented or destroyed. In addition, endangered species do not necessarily reproduce profusely in an area, as their populations are often small and declining. Finally, endangered species are not typically dangerous to humans or other animals, and in fact, many of them are vulnerable because they have been overhunted or because their habitats have been destroyed by human activities.
