The Evolution of the Ocean System

The earth’s oceans are overfished. Nearly 80 percent of commercial fisheries are overexploited and some experts believe that global fisheries will completely collapse by 2048 (Barkin page 1). While these are just facts that tell the worst-case scenario, they should be alarms that spark change in the way we fish. This paper, however, will specifically target overfishing in the Grand Banks in Newfoundland, Canada, and analyze its impact on Earth, its Environment and Humanity. Over fishing is simply when fishermen catch more fish than are being reproduced. Eventually the stock of fish in the environment will be completely depleted. That is exactly what happened off the shores of Newfoundland in 1992. With Cod fishing at an all time high, the Canadian government discovered that the Cod population was almost exhausted. New technology and poor decision-making led to the complete destruction of the cod population in the Grand Banks and this is a mistake that we should never repeat.

Oldcastle Precast of Avon, Conn. prefabricated a precast concrete pool and weir fish ladder, designed for a tributary to Hubbard Brook, Middletown, as part of the Connecticut Department of Transportation’s State Route 410 (Aircraft Road) culvert rehabilitation project.

Beginning in the 15th century, European explorers crossed the Atlantic Ocean and conquered almost all of the New World. Mexico, the Caribbean islands, and South America all became part of a vast area of European colonies known as Latin America. The British, French, Dutch, and Portuguese all had territory in this region, but the most notable conquistadors were the Spanish. New Spain included most of the Caribbean islands, Mexico, almost all of Central America, and the entire western coast of South America. Throughout all of these colonies, Spanish society was controlled by a strict social system. At the top of the social hierarchy were the peninsulares, European-born colonists who dominated the government. The peninsulares were

Meteors with 5% water help cover the Earth with water, but it was mainly because volcanoes gave of huge amounts of carbon dioxide which formed into clouds causing it to rain for millions of years.

6. What causes ocean tides? Tides are caused by the gravitational pull of both the moon and the sun. The moon being closer has a greater effect on tides. Water on the side of Earth closest to the moon bulges toward the moon. There is also a bulge away from the moon on the opposite side of the Earth.

While tides are most commonly associated with oceans, gravity creates tides in the atmosphere and even the lithosphere. Gravity is one of the major forces responsible for creating tides. Another is inertia, which is the force that acts to counterbalance gravity. Together, gravity and inertia are responsible for the creation of two major tidal bulges on the earth. The gravitational effects of the moon and the sun affect the Earth’s tides on a monthly basis.

All throughout the blue currents of the Indian Ocean, in which this body of water, over time filled with migrating people such as sailors, religious leaders, and traders. The movement of people infused the area with differing beliefs, ideas, and goods by contributing to the expansion of Eurasia and Africa. As the level of trade, innovations, and division of labor grew so did the level of globalization took place in this area of the world. The ways in which this land mass became so integrated with the level of interconnectivity, was the rate in which services and goods traveled. All these different aspects especially economically, help expand Africa and Eurasia to become a world power. The fundamental part of becoming a world power comes

Callum Roberts set himself the difficult task of cataloguing evidence that today’s oceans are depleted and struggling against overfishing and human influence, while still remaining optimistic about the future of the world’s oceans in his book The Unnatural History of the Sea. Roberts begins by painting a picture of the oceans as they may have been before human influence had drastically depleted species and changed ecosystems through fishing. From this point, he maps out centuries of development in fishing and shows how drastically changed and depleted the world’s oceans are today because of human exploitation. With the explanation of modern day fishery policy and a strong case against the practice of trawling, Roberts shows how humanity continues to exploit the ocean as if it were an endless resource. In spite of all this, the author, in the end, attempts to develop a positive outlook by explaining what can be done to stop the rapid decimation of fisheries, including reevaluation of fishery regulations and development of marine reserves.

Oceans have affected the environment by hurting animals, people, the environment itself and NOW the plants. Believe it or not, but when garbage affects our plants it also affects our animals, humans, and environment, like a chain reaction. Any plant can be affected by this pollution.

The world is filled with dark spirits from different various backgrounds, and various religions. They’re two distinctive examples involving the dark side of religion, that being Hinduism involves Asuras, and Christianity involved with Satin. While many Hindus think that the Asuras are associated with darkness, and at times are known to cooperate with gods, unlike Christians who see satin as the darkness of the world would never cooperate with God.

The colossal rents is the precursor of two oceans, the start of the oceans we have come to know as the Atlantic and Indian oceans. Sidetracked back to the topic at hand here, the breakup of Pangaea has started as has its slow but sure dance of inches-per-year. This dance will make the shape of the world we all live on currently.

The term given to the study of oceans and seas is called oceanography or oceanology. As an organized science, oceanography is comparatively new, but men have been familiar with the seas from time immemorial. The earliest human settlements were on the banks of large rivers. The Tigris, the Euphrates, the Nile and the Indus were witnesses to early human civilizations. The people living on the river banks soon discovered the immense expanse of the oceans, for all the streams and rivers of the land invariably flowed to their natural destination – the seas and the oceans. This led to the establishment of human civilizations along the seashores as well, particularly in the tropical and subtropical areas of the world.

The mapping of the ocean floor provided significant visual evidence towards the theory of plate tectonics. If the ocean floor were completely flat like many had thought it were, then it would be very hard to visualize and prove the theory of plate tectonics. What mapping the ocean floor did was show the textures and land features that could only be present at plate boundaries. The sea floor mapping showed zones of convergence where mountain ranges form miles under sea level due to plates coming together and compressing. More importantly, the undersea mapping shows zones of divergence at mid ocean ridges which are the birthplace for new plates as they bubble up from the asthenosphere.

The ocean is full of many unique creatures. From the water 's surface to the sea floor, there is a plethora of organisms we have yet to even discovered; however, even the organisms we do have data on are completely different from anything that we have previously seen on land. This gives cause to think they must have unique habits and patterns completely separate from all that we must know. (“Kelp” 1)
