Why are many animals extinct?

Answer 1

because if an animal becomes extinct like tigers they would breed them in captivity then they would carefully release them into the wild with tags they (trackers) . then would grow the population back.

Answer 2

If the animal is extinct, surely it cannot be held in anything...

There are however, animals that are extinct in the wild that have some numbers of their species in captivity. One example is the South China tiger. There are 55 in captivity, but it has been decades since one has been confirmed in the wild.

Answer 3

Humans are largely responsible when animals become extinct, endangered or threatened. Here are some reasons why animals become endangered:

Destruction of Habitat

Humans destroy precious habitat--the natural environment of a living thing--when they fill swamps and marshes, dam rivers and cut down trees to build homes, roads and other developments.

Pollution

Oil spills, acid rain and water pollution have been devastating for many species of fish and birds.

Hunting and Fishing

Many animals are over-hunted because their meat, fur and other parts are very valuable.

Exotic Species

When animals or plants arrive into a new habitat from a foreign place they sometimes introduce diseases that the native species can't fight. These "exotic" species can also prey on the native species

Answer 4

The primary reason that many animals are extinct is that extinction is the rule and NOT the exception.
While humans have been responsible a number of extinctions, the most common reasons are catastrophic events (meteor strikes, massive volcanic eruptions, non-man caused climate change, drought, inability to adapt or out compete a rival species. And the list goes on.
