ocean pollutants
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 r
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. There are things that can be done to help save our oceans and if we don't start soon it may be too late. This overabundance of nutrients is causing algae blooms worldwide, impacting the marine food web. Also stated in the article was: Water is purified in large part by the routine actions of living organisms. Energy from sunlight drives the process of down some of the organic material such as plant and animal waste. All of these things are polluting our oceans and slowly killing organisms that are vital to the environment. aw sewage into the ocean (Ocean Dumping-The Causes of Ocean Pollution; Ed Hunt, pg. In previous years major culprits were paper mills and related plants, which would release waste into the ocean. This decomposition produces the carbon dioxide, nutrients and other substances needed by plants and animals living in the water. 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. Also responsible are the factories that are located on the coast. The purification cycle continues when these plants and animals die and the bacteria decompose them, providing new generations of organisms with nourishment. The red tide blooms (dinoflagellate) have caused shellfish poisoning in humans and mass mortality of clams.
