Question

How does the population of humans affect orcas

Answer 1

Answer:

I'm guessing all the waste that goes to the ocean can harm them

Answer 2

Answer:

toxic exposure, surface impacts, and underwater noise

toxic exposure (pollution), surface impacts (fishing, boating), and underwater noise because Orcas communicate with each other over short and long distances with a variety of clicks, chirps, squeaks and whistles, along with using echolocation to locate prey and to navigate. They may also rely on passive listening as a primary sensory source.
