Extinction is a naturally occurring phenomenon that has occurred on earth, since life began, scientists are so concerned about extinction now because
1 Human activities are directly responsible for today's mass extinctions
2 Extinction is occurring faster than ever before and faster than rates of restoration
3 Large number of plant species which form the base of terrestrial food webs become extinct
4 All of these
Explanation:
Extinction is a naturally occurring phenomenon that has occurred on earth, since life began, scientists are so concerned about extinction now because the current extinction crisis is unique in that the loss of biodiversity is occurring very rapidly, and the causes of the crisis are the activities of a single species: human beings.
