How Pollution Affects Marine Life

HOW POLLUTION AFFECTS MARINE LIFE SPECIES 300 6 An autopsy on a sperm whale found dead in Spanish waters found the cause of death to be ingestion of plastic. The whale's stomach contained 24 meters of plastic. (Der Spiegel and Publico reported) According to the UN Environment Program, at least 267 marine species worldwide become entangled with, or ingest, marine debris. 86% million metric tons of plastic produced globally every year 54 million tons end of all sea turtles are affected by entanglement in, or ingestion of, marine debris, according to the UN Environment Program up in the oceans Types of plastic found inside a sperm whale. Whales, dolphins, porpoises, turtles, manatees and seabirds have all been reported to have become entangled in plastic. Manatees have been THE NORTH ATLANTIC GARBAGE PATCH found with scars or missing flippers after becoming entangled. An area of man-made marine debris trapped in the North Atlantic Gyre. The patch is estimated to be hundreds of kilometers wide, with a density of more than 200,000 pieces of debris per square kilometer. The debris zone shifts by as much as 1,600 km north and south seasonally, and drifts even farther south during the El Niño-Southern Oscillation, according to the US National Oceanic and Atmospheric 80% Administration. Studies have shown of waste is washed into the sea by rivers or carried out to the that a high proportion (about 50 to 80 percent) of sea turtles found dead are known to have ingested It's impossible to measure the exact size of the patch because much of the debris floats beneath the surface of the ocean. ocean from garbage dumps by the wind. Of the plastic that is simply trashed, an estimated 7 million metric tons ends up in the ocean every year. Of seabirds, 111 out of 312 species are known to have ingested debris. Large numbers of birds from specific species - up to 80 percent - can be affected. Plastic debris is also known to be passed to chicks in the form of regurgitated food delivered by their parents. marine debris, MIDWAY ISLAND IN THE NORTH PACIFIC 663 350,000 Although other types of debris are found in the 80% Number of different species exposed to plastic in the ocean marine environment, such as glass floats, bottles and light tubes, of debris in the Great Pacific Garbage Patch comes from land, including plastic bags.bottles and various other consumer products Albatross chicks hatch every year on Midway Island in the North Pacific metal cans, discarded A photo of a dead albatross chick from 230,000 fishing traps, nets and line, 60-80% of waste is the Kura Atoll, taken by the National Oceanic and Atmospheric Administration in the estimated to be leave the island petroleum-based plastic.
