BEACON TRANSCRIPT – We are surrounded all the time by different types of noise. Some of those noises can be quite pleasant, some of them really annoying, while other can be potentially dangerous for us. Noise pollution can indeed be considered a new form of pollution given the fact that we are surrounded by endless streams of sounds. According to a new study, noise pollution threatens marine fauna.
Air pollution is one thing, but when it comes to noise pollution, things become pretty irritating. We are surrounded all time by all kinds of noisemakers. From the simple backfire of a car to the neighbors yelling at each other in the dead of night, we revel in sounds and music. But higher intensity sounds can irreversibly damage our hearing capabilities.
If things are tough for humans, it would seem that they are even rough for the gentle creatures of the sea. According to a new study, which was published in the Nature Communications journal, the ever-increasing levels of noise pollutions are threatening several marine species.
For instance, the noise pollution generated by loud motorboats or by the sonar-based devices, have taken away the ability of damselfish to elude marine predators. The study in question demonstrates that due to the noise pollution, the damselfish are 6 times more likely to fall prey to a marauding predator because it loses the ability to identify the predator in time.
Noise pollution threatens marine fauna – this is the conclusion of the recent study the mirror the devastating impact of noise pollution on different species of underwater creatures, including the damselfish, dolphins, whales and yes, even corals.
The scientists working on the project have observed that the high levels of noise produced by motorboats or sonar are actually capable of retarding the fish’s ability to fend off predators. Damselfish affected by this issue are likely to become easy prey to any predatorial species.
And according to the same study, it would seem that even the fragile coral reefs will suffer from the ever increasing noise pollution. According to a couple of estimates, it would seem that no less than 500.000 motorboats will be passing by the Great Coral Reef barrier by 2040. This can only mean bad news for the ecosystem and the worst kind of news for the reef which is not only sensitive, but it is also capable of attracting other species of marine creatures.
Moreover, there are many species of sea creatures that rely on their hearing in order to get their bearings and to find food. In the end, the study recommends that ample measures must be taken in order to limit the noise pollution.
