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 thing
. All of these things are polluting our oceans and slowly killing organisms that are vital to the environment. There are things that can be done to help save our oceans and if we don't start soon it may be too late.
s, such as, air pollution and chemicals are dangers too.
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 marine food web. The red tide blooms (dinoflagellate) have caused shellfish poisoning in humans and mass mortality of clams.
