Question

How does military sonar affect whale behavior? Mass strandings of whales occur on beaches near military exercises using active sonar, in which sound waves are broadcast to detect underwater features. This raises concerns about the effects of humangenerated underwater sounds on animal behaviour. Scientists are collecting behavioural data on several species of whales to find out how active sonar affects them. Part A There are debates about what action the military should take to avoid harming the whales. How could you apply cost-benefit analysis to address this problem? In this moment, it is impossible to reduce the costs to whales with or without reducing the benefits to the military even if the military immediately stop using sonar. It could be possible to reduce the costs to whales with or without reducing the benefits to the military. The military could limit sonar use to locations that are far away from known whale migration routes and to times of the year when whales are not nearby It could be possible to reduce the costs to whales only with reducing the benefits to the military. The military should immediately stop using sonar. This is the only possible way to solve this problem. Submit Request Answer

Answer 1

Answer is B because it is an efficient way to tackle the situation as it limits the use of sonar to the areas where there are no whales and also providing sonar free areas on whale migration areas causing less harm to them while providing optimal benefits to the militiary.

2 In case of an Experiment one should take an area with two groups of whales one group will be subjected to low sonar levels,the other group will be isolated from the first group and sonar.

In case of an observation study data from Active sonar use and location of groups of whales should be collected expecting to find correlation between them
