Which phrase emphasizes that extinction means a species cannot come back once it is gone?

Which phrase emphasizes that extinction means a species cannot come back once it is gone?

• A. Extinction Is Forever
• B. Permanent Loss
• C. Irreversible Extinction
• D. Endangered But Recoverable

Answer: (A)

Extinction means there are no individuals left to carry on a species, so there’s no natural pathway for that species to come back. The phrase that captures this idea most clearly is Extinction Is Forever. It states in a simple, direct way that once extinction happens, it cannot be reversed, communicating the permanent end of a species. Permanent Loss also communicates permanence, but it’s broader and not tied specifically to the biological event of extinction. Irreversible Extinction adds emphasis on non-reversibility, yet it is less concise and redundant, and it doesn’t highlight the everyday sense students associate with the idea that a species cannot return. Endangered But Recoverable clearly contradicts extinction by implying recovery is still possible, so it doesn’t fit the concept.
