• Causes of the extinction
• How to fix it?
An endangered species is a population of
organisms which is at risk of becoming
extinct because it is either few in numbers,
or threatened by changing environmental
or predation parameters. The International
Union for Conservation of Nature (IUCN)
has calculated the percentage of
endangered species.
Many countries have laws that offer
protection to endangered animals: for
example, prohibiting hunting or creating
reserves.
Only a few of the many endangered
species get legal protection like pandas.

10) GIANT PANDA BEAR
There are 1600 pandas living in the jungles and 188 in captivity. Today
the populations of pandas are found only in China .
9) JAVA RHINOCEROS
It is critically endangered, only known wild population, and there are
none in captivity.
8) Monarch Butterfly
The Monarch butterfly can be found in a number of habitats like
fields, urban and suburban parks, gardens and roads. During winter
they vive in coniferous forests.
7) Mountain Gorilla
The mountain gorilla live in Virunga volcanic mountains.
Its population isn´t abundant, there are 700 species in the wild.

The fish, their food, has changed their transit routes by warming of ocean currents.
Because of that the number of individuals has declined.

left without a place to breed.
2) Polar Bear

or just keep devouring his cattle, coupled with deforestation in forest regions, have
managed to place the tiger as endangered species more alarming.
Indirect causes
•
Agriculture
Complete natural ecosystems are converted to fields where only one or a few species cultivated.
•
Environmental Pollution
Many toxic substances are released into the waste disposal process are very similar to pesticides, with
similar impacts on ecosystems.
•
Development
Forests are being cut everywhere destroying ecosystems.
•
Introduction of Species
The transfer of plants and animals from one ecosystem to another has had catastrophic effects.
•
War
Destroys not only human, too many species.
