its way to the world’s seas is classified as ocean pollution‚ however these materials built up over time. This process is known as bioaccumulation. There are many contributing pollutants to bioaccumulation in oceans such as toxins‚ marine debris‚ oil‚ sewage‚ eroded soil‚ and heavy metals. In the past‚ dumping small amounts of pollutants into the oceans‚ known as dilution‚ was not thought of to be a threat to the environment because all of the oceans combined cover 75% of the earths surface.

seen an increased trend in pollution‚ especially in the ocean. You cannot hide or run away from plastic. Plastic is literally everywhere‚ from the clothes you’re wearing to even the IV bags used in hospitals. Do you see the toys your children are playing with? Yes‚ those are also made from plastic. Plastic has made itself into an everyday essential because it’s convenient and cost effective. Plastic isn’t the only thing that ends up in the ocean. According to the Rinkesh Kukreja‚ editor of Conserve

In “Opinion: The Oceans Need the Spotlight Now” written by Politha Kohona‚ he argues the world needs to unite and take care of the ocean before it is too late. He explains this through exploring the treatment of oceans in the past and currently. Kohona believes the oceans are at risk of becoming yet another battlefield for resources. This attempt to procure resources will lead to rivalry amongst the nations of the world and put the oceans and the fragile ecosystems within at risk. The risks will

SALINITY AND DEEP OCEAN CURRENTS OVERVIEW Ocean currents arise in many different ways. For example‚ wind pushes the water along the surface to form wind-driven currents. Deep ocean currents are caused by differences in water temperature and salinity. In this experiment‚ the students will hypothesize the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents. CONCEPTS Salt water is more dense than fresh water‚ and is therefore

The Affects of Ocean Acidification on Marine Ecosystems Ocean acidification is the ongoing warming and decreasing of pH in the earths water supply (Gray et al. 2016; PMEL 2017). The acidification is caused from the increase in carbon dioxide concentration within the earths atmosphere. The carbon dioxide then reacts with the water to produce carbonic acid and carbonate ions thus‚ decreasing the pH. Ocean acidification affects the ecology of everything on this planet. Mainly‚ the marine ecosystems

With every drop of water‚ I drink‚ every breath I take‚ I am connected to the sea. How do plastic bags affect our ocean? Plastic bags affect our environment by getting into soil and slowly releasing toxic chemicals. Most ocean pollution starts out on land and is carried by wind and rain to the sea. Now‚ the plastic bag pollution does not only affect humans‚ it also affects animals. Plastic bag pollution affects our economy‚ costing us untold dollars spent in beach cleanups‚ tourism losses and damages

In The Truth about Ocean “Acidification”‚ by Patrick Moore‚ the term “ocean acidification” has been fabricated‚ and people do not see the positive effects it has on marine life. In 2003‚ many articles on ocean acidification were published. Moore challenges one of the article’s hypothesis that corals will cease to grow by mid-century‚ and ocean acidification will impact fisheries worldwide. Moore emphasizes that there are five key reasons why the ocean acidification narrative is a fabrication. First

Ocean Spray had facilities near Middleboro‚ Massachusetts where the processing of cranberries took place and they knowingly used the towns waste treatment facility for their waste water. This was not a problem until new water standards came about and the problems associated with Oceans Sprays activities came into light. Sludge started to grow in the waste treatment facility so the Massachusetts Department of Environmental Quality and Engineering became involved. The cause of the sludge was because
