Question

Mass strandings of whales occur on beaches near military exercises where sonar is used, raising concerns about the effects of human-generated underwater sounds on animal behavior. Scientists are collecting behavioral data on several species of whales to find out how sonar affects them.

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?

Accepted Answer

Welcome back. Here's our next question. Which migratory animals are the most heavily impacted by wind energy production. Wind energy is produced by wind turbines which are very, very large, very tall, powerful windmills. And of course when we think about migratory animals traveling over long distances, it's going to be animals that are flying obviously that get impacted by these wind turbines. And indeed we've been seeing fatalities due to collisions of soaring birds with wind turbines, especially because there's been increased numbers of turbines in migratory quarters for these birds. So when we look at our answer choices, we see that choice D. Is birds obviously Choice zebras and Choice B. Choice C. Elephants travel by land. They aren't going to be affected by turbines and Choice B is salmon, which would travel from oceans to the river. So also not affected by turbines, so which migratory animals most heavily impacted by wind energy production, Choice D. Birds. That was a nice easy one for us. We'll see you in the next video.
