World Ocean

Sharks There are more than 465 known species of sharks living in our oceans today. Sharks are an apex predator and are at the top of the food chain. They help control the population of fish below them in the food chain. Research has shown that the decrees in shark population has had a major effect in the oceans eco system. Species Diet Most species of sharks eat the normal fish, meaning they eat, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have an…

Therefore, without coral reefs there will be no life cycle in the ocean (Environment 911, 2011). According to Marine Animals, more than 100,000 sea animals die every year due to ocean pollution, one cause is ingesting plastic. As a result of this, the animal will feel full because the nondigestible plastic will remain in the animal’s stomach taking up space for the animal’s real food source, this can cause malnutrition, dehydration, and starvation (Save Our Shores). In addition, if the…

Feces, acid, and cancer are jeopardizing the lives of the human and marine species around the world quite possible destroying the entire planet. Maybe it is many years away, but why just sit around and wait for it to happen? Sewage facilities and manufacturing industries are the primary culprits behind disease repleted water, acidic oceans, and cancer causing agents in tap water, either follow proper regulations or getting around them. There are many means to limit the costly effects that sewage…

baiting/cage diving. People need to change their attitude towards sharks because they are a vital part of ocean ecosystems as a top predator, and just mindlessly killing them is not smart or moral. Carl Safina, an ocean expert and author of many books about the ocean, has written Song for the Blue Ocean, in which he advocates for a “sea ethic.” This sea ethic is an idea that humans must respect the ocean and its inhabitants in every respect, much as we respect land animals. What cage diving and…

exploring the Ocean, here is the information that I have gathered so far. The Ocean covers over 70% of the Earth’s surface, it holds about 320 million cubic miles of water, which is over 97% of Earth’s water supply. The Temperature of the ocean varies from top to bottom. The upper layer which is about 200ft down is warmer that the lower part , the thermocline, because the top gets warmed by the sun. The temperature of the water can affect the productivity of organisms living in it. The Ocean…

In second grade I gave up eating seafood because I wanted to be a marine biologist. My logic? I didn’t want to “eat what I worked with” as I studied the ocean. Ten years later and I feel even more enthused about our oceans. For me they are still a wonder; worlds still mostly undiscovered and unknown. Although my life is not necessarily how I pictured it at age seven, there are two things that remain unchanged: I still don’t eat seafood, and I still want to be a woman in STEM. Looking back on…

century. If this were to occur, global sea levels would rise by 230 feet. This would eat away at all the worlds coasts wiping away thousands of families homes. In general, sea ice is moderated by the sunlight. Like most ice it melts in the summer and refreezes during the winter. Most of the time during the winter it will grow to larger ice sheets. But in recent years this is not the case. Warm ocean currents move north from the equator causing warmer waters to travel to the arctic ice regions…

storm days at school. I heard on the news that we are predicted to not have very much snow this year and have a very hot summer because global warming has affected the climate so much. My view on global warming is that it exists. Everyone in the world needs to cut down on driving. Combustion engines create so much pollution that they are the number one reason for global warming. The greenhouse gases are affecting our atmosphere creating a way warmer Earth, which then has an impact on almost…

local extinction of organisms” (). Removing nodules can also lead to the pollution of water around the area. Anything lying on the ocean floor ends up getting mixed up into the water, leading to the clogging of fish gills and possible physical damage to organisms, from rocks, shells, or other debris. Little has been done to moderate deep sea mining. In an ideal world, deep sea mining should be eliminated all together, but its impacts are only expected to increase as demand…
