ocean pollutants essays

ocean pollutants essays Pollution in our oceans is a serious problem. According to Marie Wild in her article "Ocean Pollution", "Ocean pollution is one of the major killers of our sea animals.". Most of the waste that is dumped is plastic, which takes hundreds of years to break down (Oceanic Research Foundation [ORF]). Everyday millions of animals are caught in fishing nets and six pack beer rings. It is thought that only fish are affected from getting caught in these. In reality they also kill birds, turtles, dolphins and seals. The animals are slowly strangled or suffocated by the rings as well as cans, fishing line, nets, kite strings and ropes (Wild). Or, as stated be the National Wildlife Federation (NWF), they die from accidental consumption (NWF website). Garbage is not the only threat to the safety of our oceans though, other things, such as, air pollution and chemicals are dangers too. Ships cause much of this pollution, often dumping raw sewage into the ocean (Ocean Dumping-The Causes of Ocean Pol lution; Ed Hunt, pg. 37). Also responsible are the factories that are located on the coast. These factories often, in search of easy disposal, will dump chemicals into the ocean. In previous years major culprits were paper mills and related plants, which would release waste into the ocean. A large increase could lead to long term rises in the levels of water mutagens, pathogens, teratogens and radioactive materials (Hunt 46). An article from ORF, "Oceans at Risk-Problems and Dangers Affecting our Oceans", reads: From the land, high levels of pesticides and toxins are being carried to the oceans, dramatically affecting shallow coastal zones, sea grass marine nursery areas, and coral reefs. Over sixty percent of the raw or treated sewage produced by man, rich in nitrogen, is being dumped into the oceans causing eutrophication in coastal waters. This overabundance of nutrients is causing algae blooms worldwide, impacting the ...
