Coastal pollution is a substantial threat to marine biodiversity loss globally. For #ThreatThursday
here’s five facts about coastal pollution and its impacts.
💔 An island of waste exists within the Pacific Ocean double the size of Texas. The North Pacific Gyre off the California coast is the largest oceanic waste site on the planet. Within the immediate vicinity, the quantity of floating plastic pieces outnumbers the total marine biomass 6:1.
💔 Plastic is the number one source of pollution in our oceans. It does not degrade, but instead, breaks down progressively into smaller pieces (microplastics), but it does not ultimately disappear. This plastic debris can absorb toxic chemicals from other sources of oceanic pollution. When the plastic or microplastic is ingested by marine life, these chemicals bioaccumulate within the organism..
💔 Fertiliser runoff, mainly from agricultural output, causes eutrophication that creates an algal bloom (rapid increase in algae population within an aquatic system). This algal bloom depletes the oxygen concentration within the water, affecting marine life and their food webs, and ultimately contributes to marine life death..
💔 Eutrophication has contributed to enormous dead zones within numerous parts of the world, including the Gulf of Mexico and the Baltic Sea..
💔 Over one million seabirds and 100,000 sea mammals are estimated to be killed by ocean pollution annually. Approximately 300,000 dolphins and porpoises died due to being entangled in ghost fishing nets and other debris.
