Additionally, not only does the ocean's absorption of excess, human-generated CO2 change seawater acidity and cause corals to bleach ( or even dissolve), but increases in oceanic CO2 levels also reduce the oceans' capacity for dampening noise pollution. ![]() ![]() Ship engine and drilling sounds can disorient young corals ("larvae") while they search for a habitat to settle in. In fishes, chronic noise pollution can damage tissues ( including puncturing ears) and even cause organ failure.Ĭorals - which are, in fact, animals - provide habitat for a wide variety of sea life across the planet and are also threatened by noise pollution. For example, sperm whales near the Canary Islands that are desensitized to boat sounds will often strike them these collisions are sometimes fatal for the whales.
