Options

Answer 1

When a species goes extinct in one area, it is often desirable to re-introduce the species from other populations. A major problem with this approach is that populations are often adapted to local conditions and may not survive when moved to a different location.

Explanation:

When foreign species are intentionally or unintentionally introduced for any reason, some of them become invasive and contribute to the decrease or extinction of native species. It is frequently desirable to reintroduce a species from other populations when it becomes extinct in one region. The method has a significant flaw in that populations frequently adapt to local conditions and may not survive when relocated.
