Endangered Species
When an animal’s habitat or living space, is destroyed by humans, the animal
can become an endangered species. Endangered species are kinds of animals that
could face extinction (all members of their species dying out) if something is not
done to change the way that humans are interacting with them. As human
populations increase, more and more space is needed for people. Construction
projects are pushing animals out of areas where generations of their ancestors
have lived the whole lives.
Forest and swamp habitats are especially threatened. Trees are cut down for
home and business construction projects, and swamps are filled in so that
neighbourhoods can expand as the number of people continues to increase in
certain areas.
To prevent tne extinction of animals because of their loss of habitat, humans have
to become more conscious of animals’ populations when considering building
and expansion projects. Even if a different option may not be as convenient as
using the land occupied by animals, but the survival of the animals need to be
taken into consideration, too. Better planning and an awareness of how human
actions affect animals populations can go a long way toward making sure a
diverse animal population will be here for future generations to enjoy.
