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
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
Causes of the extinction

• Natural causes
• Aging
• Illness
• Other animal competence
• Natural catastrophes
• Fire
• Drought
• Hurricanes

6
Causes of the extinction

• Not natural causes
• Pollution
• Poaching
• Exploitation
• Ignorance

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
Impact on organisms

• Extinction becomes more likely
• Decrease the range of certain organisms
  populations

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
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
Conditions that lead to invasion

• Fast growth
• Rapid reproduction
• High dispersal ability

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
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
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
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
Endangered species

• These species are at risk of becoming extinct,
  because for different reasons
• Theres a list that has calculated the percentage
  of endangered species around the world (The IUCN
  Red List)

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
