Final Answer :
C
Explanation :
The current extinction crisis is caused by human activities such as habitat destruction, pollution, and climate change, while previous mass extinctions were largely caused by natural disasters.
Answer: B
The current extinction crisis is happening at a much faster rate than previous mass extinctions. It is estimated that extinction rates are currently at least 1000 times higher than natural background rates.
Note: None of the answer choices are accurate, so the best answer is a combination of both choices B and C.
