Ocean OverfishingNicole HarrisENV/320June 23‚ 2014Frederick GrossOcean Overfishing Overfishing is a problem that occurs when fish are caught faster than they can reproduce. This is a problem that has been occurring for centuries and continues to be a problem today. Commercial fishing has driven many fish species to the brink of extinction. A scientific report done in 2003 estimates that industrial fishing “has reduced the number of large ocean fish to just 10-percent of their pre-industrial

activities. Due to the massive production of waste and the excessive need for daily materials‚ oceans are becoming more and more polluted; in addition‚ result to damaging effects on marine life. The ocean appears to be a large trash can for disposing waste in the convenience for humans. According to UNESCO‚ statistics show that in 2006‚ 46‚000 plastic materials were found scattered every square mile in the ocean; in addition to that statistic‚ millions of marine animals are severely injured or even fatal

“what is destroying the ocean?”. Well one of the many answers is microplastic. Microplastics are little pieces of plastic that are smaller than 5 millimeters. Microplastic is harming zooplankton in many ways ‚ but not only zooplankton a lot of other fish also in many ways. When people leave plastic on the ground it eventually makes its way to the ocean . Microplastics are thrown into the ocean by people which is causing fish to die. There is a lot of microplastic in the ocean which is a serious problem

Ocean Park vs. Hong Kong Disneyland History about Ocean Park Officially opened on 10th Jan 1977 by the Governor of Hong Kong‚ Sir Murray MacLehose‚ the Ocean Park was constructed with HK$150million funded from the racing profits earned from the Hong Kong Jockey Club while the land was given free by the Hong Kong Government. It is located in Wong Chuk Hang and Nam Long Shan in the Southern District of Hong Kong. The park has won several awards‚ including The World ’s Seventh Most Popular Amusement

Ocean acidification is the continuous reduction of the ocean’s pH‚ carbonate ion concentration‚ and saturation states of biological calcium carbonate minerals. Ocean acidification is caused by the uptake of carbon dioxide from the atmosphere. According to “Ocean Acidification: The Other CO2 Problem‚” after the industrial revolution‚ carbon dioxide levels in the atmosphere has increased nearly 40%‚ primarily due to the burning of fossil fuels and deforestation (Doney S. 2009).

decrease) in salinity around the equator? Could it not be argued that higher temperature causes more evaporation from the ocean surface‚ which‚ in turn‚ results in higher salinity content? Figure 9.4 shows how the surface temperature of the ocean and the surface salinity change with latitudinal position. Salinity the measure of the concentration of dissolved salts in the ocean water. Salinity influences where plants and animals can thrive‚ and also affects aspects of water quality and treatment

Keeping oceans young and productive: - Upwelling and Downwelling Oceans cover two thirds of our planet thus they can be regarded as one of the major factors in shaping this blue marble in space. But oceans just don’t result in varying gradient of humidity that gives rise to different vegetations and ultimately widely different biomes when coupled with other factors such as differential exposure to solar radiation‚ and inherent soil type. Oceans are living systems that themselves support numerous

Conclusion The chemical changes in ocean acidification is known to be caused by an increase in the concentration of carbon dioxide (CO2) in the atmosphere‚ resulting in the lowering of the pH making water more acidic‚ an increase in dissolved carbon dioxide (CO2)‚ a reduction in the concentration of carbonate ions and an increase in bicarbonate ions. The oceans are currently taking up about one ton of carbon dioxide (CO2) associated with human activities per year. Almost half of the carbon dioxide
