Imagine that you're a young child and you've lost track of your mother in the grocery store. You call for her, but there is such a loud cacophony of sounds (chitchat, buzzing, scraping, music)
that she cannot hear you
, and you cannot hear her desperately calling for you. This is what it might be like for marine animals along our busy coasts.
You see, ocean life requires sound to survive. From tiny organisms to giant blue whales, ocean life-forms use sound to communicate with each other. A little dolphin baby might cry out for its
mother from hundreds of feet away, Unfortunately, however, the human hustle and bustle on the coastline can interfere with underwater conversation. Human sound is actually more invasive
than we might think.
Sound travels 4.4 times faster underwater than in air.
Honking cars, loud music, chuming machinery, and other noises can make it more difficult for marine animals to understand each other and, therefore, survive. While you might not realize it,
humans' racket could be costing marine creatures their lives. That is why it's imperative that we create sound sanctuaries around vulnerable ocean areas. With a few simple restrictions on
human behavior, marine
creatures can have the heart-to-hearts they need to survive and thrive.
