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.

“The Acid Sea‚” Elizabeth Kolbert wrote about how the polluted sea around Castello Aragonese provides us with a glimpse of our future oceans and how it interferes with the chemistry of the ocean. In the article “Our Oceans are Turning into Plastic … are You?‚” Susan Casey discusses the negative effects plastic has on the environment. “The Acid Sea” and “Our Oceans are Turning into Plastic … are You?” did an excellent job with providing strong arguments and appeals to inform and persuade the reader

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

Case Study of the Indian Ocean Tsunami On December 26‚ 2004‚ the Indian Ocean earthquake‚ or the Sumatra-Andaman earthquake‚ caused a tsunami that killed 230‚000 people and was recorded as the deadliest tsunami in known history. The earthquake was recorded as between 9.1 and 9.3 on the Richter scale‚ the second largest earthquake ever recorded. It was also recorded as the longest one‚ triggering earthquakes as far away as Alaska. Following the disaster‚ a worldwide effort raised billions of dollars

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

The Indian Ocean is one of the oldest trade routes between Africa and Asia. During the early days of Indian Ocean trade‚ the buying and selling of goods took place only between the Swahili people living in East Africa and Arabs from Asia. Indian Ocean trade was made easy by the monsoon winds that circulated between Asia and the Eastern coast. These winds blew north to the south and from the south back to the north in a circular fashion. These winds change direction with the change of seasons. In

Ocean Acidification Climate change’s equally evil twin seems to be ocean acidification. 25 percent of the CO2 dissolves into the ocean instead of being in the air. When the industrial era started over 525 billion tons of CO2 were absorbed (22 million tons per day). Scientists at first thought that we were good because it warms the planet‚ but that’s not the case. The ocean is becoming more acidic than ever because of the CO2. 200 years later the water temperature increased by 30 percent. Rivers usually

concerned about Global warming‚ ocean acidification‚ and pollution. Scientist are mainly concerned with global warming because it’s affecting our food and water supply. Pollution is also a serious issue that scientist are researching because scientist still don’t know how much it’s affecting our food chain. Ocean acidification is a serious issue too because it’s causing parts of the ocean to unsaturate. A reason for ocean acidification is excess of carbon dioxide making the ocean more acidic than what it

Beginning in the southeastern Vic city of Torquay and stretching a full 244 kilometres to the city of Allansford near Warrnambool‚ lies what has been labeled by many as the greatest example of scenic coastal road engineering that exists: The Great Ocean Road (TGOR). Having been actually built by returning World War I Aussie soldiers‚ TGOR today still stands as the world’s largest war memorial. This architectural wonder consists of a two-lane road‚ one lane in each direction. As it travels through
