Question

The Chesapeake Bay is an important natural resource. Over the years, the number of oysters in the bay has declined dramatically, largely because of fishers who catch them and sell them as food. This has affected many other organisms that depend on oysters. This is an example of which type of short-term human-induced environmental change?

A.eutrophication
B.non-sustainable harvesting
C.nonnative species introduction
D.pollution

Answer 1

B.non-sustainable harvesting

Answer 2

Answer: B. Non-sustainable harvesting.

Step-by-step explanation:

Non-sustainable harvesting is a practice in which the resources are consumed in a way that not appreciable amount is left. This is a short term human induced environmental change. Such a change may last for a short period of time and the damge caused by the change will be recovered by the environmental conditions.

The oyster population which is being overexploited due to non-sustainable harvesting by fishing and depleted will recover in future with the few remaining members of the population. Hence, it is a short term human induce change.
