  2. 2. Index Species extinction Habitat destruction Invasive species Poaching Endangered species Graphics
  3. 3. Introduction Conservation is based on the resource use, the allocation and protection. Its first objective is to keep the biological diversity. Its second objective is the conservation of the energy. The people who practices the conservation are named conservationists.
  4. 4. Species extinction Extinction is the end of an organism or a group of them. The moment of the extinction is normally considered as the death of the last survivor of the species.
  5. 5. Causes of the extinction Natural causes  Aging  Illness  Other animal competence Natural catastrophes  Fire  Drought  Hurricanes
  6. 6. Causes of the extinction Not natural causes  Pollution  Poaching  Exploitation  Ignorance
  7. 7. Habitat destruction Habitat destruction means the natural habitats that for different reasons are unable to be used by the species. One of the reasons of the destruction is the human activity. Habitat destruction is a primary cause of species extinction.
  8. 8. Impact on organisms Extinction becomes more likely Decrease the range of certain organisms populations
  9. 9. Solutions Remain intact different sections of natural habitat Educate the public about the importance of the nature Considering adding services that provide the natural habitats prosperity
  10. 10. Invasive species They are species that have been introduced in a place that is not their usual habitat These species produce changes to the composition and the structure of the ecosystem Humans have changed their habitats, voluntarily or involuntarily
  11. 11. Conditions that lead to invasion Fast growth Rapid reproduction High dispersal ability
  12. 12. Stages of the invasion 0 – No danger 1 – Traveling 2 – Introduced 3 – Localized but rare 4a – Widespread but rare 4b – Localized and dominant 5 – Widespread and dominant
  13. 13. Poaching It is the illegal taking or hunting of a big number of organisms, especially these who are considered endangered species There are a lot of reasons to punish the poaching Illegal logging is also another form of poaching For example, in Philippines there are 400 animal endangered species that are illegal to hunt
  14. 14. Traditional Chinese medicine It often incorporates ingredients from plants, animals and minerals Parts of endangered species are used Poachers sell parts of these species in the black market
  15. 15. Slips of authority In Africa, although hunting for ivory was banned, poaching of elefants continues. In the USA some endangered species are only banned from fishing in a few states
  16. 16. Endangered species These species are at risk of becoming extinct, because for different reasons There’s a list that has calculated the percentage of endangered species around the world (The IUCN Red List)
  17. 17. IUCN Red List Extinct: Woolly mammoth, Dusky Seaside Sparroow Extinct in the wild: Hawaiian Crow, Wyoming Toad Critically endangered: Mountain gorilla, Bactrian Camel Endangered: Blue whale, Giant panda Vunerable: Cheetah, Lion Near threatened: American bison, Tiger shark Least concern: Pigeon, Giraffe
  18. 18. IUCN Red List
