~ POLLUTION ~ Ask most people about pollution, and they will think of rubbish, plastic, oil, smog, and chemicals ☢️🚯When you hear that word - what do you imagine? Have you ever thought about noise pollution? 🎵🔇🎵
Marine mammals rely heavily on acoustic communication. Light doesn’t reach far under water. So many marine animals have evolved to “see with sound”, using acoustics for navigation, for detecting predators and prey, and for communicating with other members of their species. And our man-made sound can interfere with these behaviours. 🛳✈️⛴
Before I go on about this (and as an acoustician believe me- this topic is close to my heart and what I study!) I urge you to watch "Sonic Sea". A real eye opener.
And before you feel the doom and gloom of conservation issues we face today - find solace in knowing that one positive in all of this is that even though noise pollution travels very fast and very far through the ocean, the moment you switch off the source, the noise is gone. This is very much unlike plastic or chemical pollution, and gives us hope that noise pollution can be successfully managed.
Here's some Bremer killer whales out near the shipping channel. Bremer really is a unique area, so far offshore in a pristine environment- let's keep working to keep it that way! •
