How does an extinct animal become endangered?

Answer 1

This is a listing of the causes of endangerment for animals.

There are many different causes of endangerment. Some are species specific, others are general. These are some of the general factors that apply pressure to populations.

1.) Unregulated, or unrestricted commercial hunting or fishing has driven species to extinction.

2.) Poaching (trapping, hunting, and capturing) any protected species for the purposes of profit.

3.) The Black Market, and "Traditional Chinese Medicine" selling items such as; animal body parts, organs, pelts, tusks, horns, also trophy purchases, and this drives the values of the endangered species.

4.) Loss of natural habitat through, natural disasters, human encroachment, river management, or coastal growth, land management and land use.

5.) Careless waste disposal, and dumping, species suffer long term exposure, become entangled in the trash, eat it mistaking it for food, and die.

6.) Pollutants are spilled, leaked or dumped, into environments, and exposure to the toxins and other deadly chemicals, can kill species, with long term effects in the food chain, and even destroy whole ecosystem and habitats.

7.) Nonnative or exotic species, can destroy a balanced ecosystem of native species.

8.) Mutated diseases, and viruses become resistant to common treatment, inter-species transference, including native, nonnative species, and human exposure.

9.) "Climate Change" Recently studied by IUCN Red List as "climate change susceptibility", and US Fish and Wild Life Services for the Endangered Species List.

10.) "Specialized" Species by their very nature, are at a higher risk of endangerment, than the more widely adaptable species.

Any number of these factors combined or working alone, can cause the growth rate of a species to decrease to such a level that they are considered to be endangered.
Animals are becoming extinct every single day and humans are behind it all.

Humans hunt animals for there fur or tusks and about 1 species disappears in 1 year. Poachers come with their guns and kill the animal they were hunting, grab what they want, and leave the rest of the body there because they only came for one thing. That one thing was very valuable and the poachers would leave without looking back.

Another way animals become extinct is that their habitat was destroyed.
Either by being hunted by humans, or being hunted by other animals. That is why it is illeagal to kill certain animals. ex: A lion isn't endangered because no one ( or nothing will hunt it.)

Answer 2

Animals end up on the endangered list, primarily through human impact. Human activities that cause endangerment are:

• Habitat destruction and land clearing for housing, business and industry
• Introduction of non-native, invasive species
• Pollution
• Poaching

Monitoring of species numbers by scientists and conservationists keeps the authorities informed of when a species reaches a specific critical point in its population. At this point, the species is declared "endangered".

Answer 3

An extinctt animal cannot be endangered. Do you mean how an endangered animal becomes extinct? Endangered animals become extinct by various reasons. It depends what animal it is. Most animals are killed by humans, or habitats destroyed. E.G: Tigers have become endangered because of poaching, and if this continuses, then they will become extinct. Animals become extinct becuase of a particular reason, which makes them endangered, then if carried on, extinct.

Answer 4

they main reson animals are endangered is because of poaching and destroying ther habitat. also because of pollution and many more resons

Answer 5

Animals become endangered by Hunting, Trapping, Toxic gas's released in the air, and other things that may be harmful to the earth can also be harmful to animals.

Answer 6

humans
