Another student reminds you of the picture taken of the spherical Earth from the moon landing. Your teacher explains the ancient observation that when the Sun was directly overhead on one day near the equator, a pole some hundreds of miles away to the north still cast a shadow.

How is a society likely to address the problem of overuse of wildlife
Marianna [84]

Answer:

C. By creating laws or traditions that regulate hunting and fishing

Explanation:

Wildlife resources refer to wild animals (terrestrial, aquatic etc) in their natural habitat. Wildlife is an integral part of our society, however, they are being overexploited by human activities.

According to the options in the question, one way to address the problem of over use of wildlife resources is by creating laws or traditions that regulate hunting and fishing. Laws that compel hunting and fishing, which are the means humans over use wildlife, will help bring the rate at which these resources are used.

For example, creating a law that prohibits hunting in certain areas will help preserve wildlife in that area because it is a punishable offence by the law to hunt. Hence, wildlife resources will be preserved.
