Noise pollution in oceans continues to grow

Many scientists around the globe will agree that noise pollution in oceans is very serious environmental issue that could cause serious damage to marine food chain. Ever increasing noise pollution in our oceans has increased dramatically in the last couple of years, and fish and other marine species are finding it very hard to separate natural sounds from artificial sounds.

What this means is that fish can be attracted with the wrong sound which can even lead to serious decline of many fish species. Scientists are worried that in noisy environments the breakdown of natural behavior would likely result in devastating impacts on fish procreation and future fish stocks.

Several latest studies have showed that fish can accidentally learn to follow the wrong sounds, and by following these sounds they could end up stuck next to a construction site or follow a ship back out to sea, situations that will likely result in death.

UK-led team working on the Great Barrier Reef recently said that young fish is particularly sensible to noise pollution. Dr Steve Simpson, Senior Researcher in the University of Bristol's School of Biological Sciences pointed at this danger by saying that "when only a few weeks old, baby reef fish face a monumental challenge in locating and choosing suitable habitat. Reef noise gives them vital information, but if they can learn, remember and become attracted towards the wrong sounds, we might be leading them in all the wrong directions."

Wrong direction in marine world in most cases leads to a certain death. If noise pollution continues at this pace in our oceans many fish species will experience severe decline in population in years to come.
