PART B_2
Noise pollution poses threat to marine life
Aside from the surface and temperature, new study suggests human activities also change the sound of oceans and seas on our planet. While this may seem trivial, this actually has an impact on sea animals regardless of size.
According to experts, sound can extend far downward underwater. It is also easier for fish to sense their environment with sound rather than light. It turns out that sound helps sea animals to communicate with each other. Many of them rely on sound to locate food and steer clear of predators. It is also useful for spotting suitable places for mating. Having said that, sound is crucial in marine life’s survival and sustainability.
However, louder noises generated by humans overpower the natural sounds undersea. Sounds derived from human activities such as marine vessel traffic, motorized fishing vessels, deep-sea exploration, and coastal construction interrupt the sounds underwater marine animals need for survival.
Experts have also observed that the population of sea animals has declined by about half since 1970. According to their records, marine creatures singing and calling are now fewer. They stress that noise pollution needs as much attention as climate change, plastic pollution, and overfishing.
