 Extinction of animals:

Skeleton of  extinct dinosaur 

definition of extinction,

"The dying out of species". Extension occur when species are diminished because of environmental forces(such as Habitat fragmentation, Global change, Natural disasters, Overexploitation of species for human use)or because of evolutionary changes in their members (such as Genetic inbreeding,Poor reproduction, decline in population number).

Reasons of disappearance of species:

Global biodiversity us much faster then natural extinction due to change in land use, unassailable use of natural resources, climate change.land conversion by human, resulting in natural habitat loses.

Species loss is also compounded by;

Population of human 

1: ongoing growth of human population and unassailable consumer life style.

2: Increasing production of waste material and population.

3:urban development.

4: International conflict.

The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.

Description

The woolly mammoth is a species of mammoth that lived during the Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene.

                Coelodonta antiquitatis

The woolly rhinoceros is an extinct species of rhinoceros that was common throughout Europe and Asia during the Pleistocene epoch and survived until the end of the last glacial period. The woolly rhinoceros was a member of the Pleistocene megafauna.

Even in present era some animals are goes extinct.,such as turtle,salmon fish.

Here are we talk about  extinction go sea turtle,

Sea turtle:

Sea turtles are endangered, which means they're in danger of becoming extinct, or disappearing forever. People cause many threats to sea turtles.

Causes of Tuttle extinction,

Pollution - When we pollute the water with trash or chemicals, the water becomes less safe to the animals who live there. Leatherback turtles eat jellyfish, which look a lot like plastic. When these turtles eat plastic bags, they can choke and die. Pollution with chemicals may also lead to diseases in sea turtles.

Turtles died because of pollution

By catch - Catching fish for food is a big business. The problem is by catch, which happens when fishermen accidentally catch other animals like sea turtles. Sea turtles can be hurt or killed by nets and tools.

Salmon fish:

Salmo salar

The Atlantic salmon is a species of ray-finned fish in the family Salmonidae. It is the 3rd largest of the Salmonidae and can grow up to a meter in length. Siberian Taimen, and Pacific Chinook Salmon can be larger, with Taimen reportedly able to grow to 6 ft long.

Scientific name: Salmo salar

Family: Salmonidae

Class: Actinopterygii

Kingdom: Animalia

Order: Salmoniformes

Lower classifications: Ouananiche, Bleke

Found in: Loch Ness, Lake Champlain, Vättern, Saimaa, Lac Massawippi, Reservoir Baskatong, 

Most salmon species live 2 to 7 years (4 to 5 average). Steelhead trout can live up to about 11 years. Learn more: Questions and Answers about Salmon.

Reasons of salman on going to extinct:

Many salmon stocks are seriously threatened by what are called the "four H's": Habitat destruction, Hydroelectric dams on migratory rivers, over-Harvest of rare stocks, and competition with Hatchery fish. ... Threatened means they are likely to become endangered in the near future.
