What´stheproblem? 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.

Causes of theextinction Direct causes • OveruseThe global exploitation of animals has caused many species become extinct or be in danger. • HuntingHunting has been a major factor in the extinction of certain species. Many are hunted for their fur; others for food... • CollectionA lot of animals and plants are collectedforscientific and medicalresearch, and fordisplay in zoos. • Persecution of Natural PredatorsMany human beings believe that some wild animals are a threat to their farms and kill them.
Causes of theextinction Indirect causes • AgricultureComplete natural ecosystems are converted to fields where only one or a few species cultivated. • Environmental PollutionMany toxic substances are released into the waste disposal process are very similar to pesticides, with similar impacts on ecosystems. • DevelopmentForests are being cut everywhere destroying ecosystems. • Introduction of SpeciesThe transfer of plants and animals from one ecosystem to another has had catastrophic effects. • WarDestroys not only human, too many species.
Howtofix? • Obtain their cooperation to protect habitats and create new nature reserves. • Avoid indiscriminate deforestation of forests, to protect the habitat. • Prevent environmental pollution (air, soil, water) • Avoid traffic and illegal marketing of animals and plants which are endangered. • Encourage the use of artificial insemination techniques in endangered animals to increase the number of individuals. • Avoid hunting in closed season. • Prevent exploitation and modification of natural habitats of the species. • Help organizations who are responsible of rescuing the last specimens of endangered animals and keep them in captivity in a habitat similar to their natural habitat.
