How does the population of humans affect orcas

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

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.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
