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.

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.

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.

Impact on organisms Extinction becomes more likely Decrease the range of certain organisms

populations

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

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

Conditions that lead to invasion

Fast growth Rapid reproduction High dispersal ability

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

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

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

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

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)

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
