Endangered species are plants or animals in immediate
danger of extinction. While extinction may be a natural
process, the rate of extinction has been dramatically
accelerated by pollution, development and other industrial
activities. As a result, we are losing up to 100 species each
day compared to the natural extinction rate of only one
species every 100 years.
EXTINCTION
In biology and ecology, extinction is the disappearance
of a species or group of species. The moment of
extinction is generally considered to be the death of the
last individual of that species. In species which
reproduce sexually, extinction of a species is generally
inevitable when there is only one individual of that
species left, or only individuals of a single sex.
Extinction is not an unusual event in geological time—
species are created by speciation, and disappear
through extinction.
There have been periodic mass extinctions, in which many species have
disappeared in a relatively short period of geological time. The most
recent of these, the K-T Extinction at the end of the Cretaceous period,
is best known for having wiped out the dinosaurs.

How can you help Endangered Species?
• Know the legislation
affecting wildlife in your
country
• Support exisiting National
Parks
• Work to establish more
National Parks
• Plant trees and plants that
help wildlife
• Never buy undersized
marine products
• Neuter and spay cats and
dogs
Let’s not let them disappear forever!
