The Unnatural History Of The Sea

The reading that I chose for this assignment is from Chapter Six in the required book for class “The Sixth Extinction: An Unnatural History”. The chapter title is “The Sea Around Us” where the primary concentration of the chapter was the consequences that humans have on the planet with the focus on ocean acidification. This happens from the carbon dioxide we pump into the air and it slowly seeps back down into the oceans and slowly increases the PH level thus causing the ocean to be more acidic. In about one hundred years do you believe that, oysters, mussels, and coral reefs survive?

Economic activity and our environment have been closely linked since man first discovered the concept of trade. In the language of economics, the environment has itself, become an increasingly “scarce resource1”. Since economics is about managing these scarce resources, it will be a useful tool when considering some of the environmental issues facing our planet. One of the major concerns confronting the environment today is the overfishing of the world’s oceans, depleting some species to near extinction. With continued advances in technological and industrial proficiency, fishing vessels are able to fish across the globe, further exacerbating the effects of overfishing. Because the oceans are considered a shared or common

The film The Sea Inside shares the heart warming real life story of a man named Ramon Sampedro. At the young age of twenty-six he suffered an accident while diving into shallow waters of the ocean that left him a quadriplegic. Now at the age of fifty-four, Ramon must depend on his family to survive. His older brother Jose, Jose’s wife, Manuela and their son Javi do their best to take care of Ramon and make him feel loved. Although Ramon is extremely grateful to his family and friends for their help all these years, he has come to see his life as aggravating and unsatisfying. He wishes to die with the little dignity he has left in his life. However, Ramon’s family is dead set against the thought of assisted suicide and the

Overfishing is a death sentence to the world’s oceans. As technology continues to improve a great deal of fish can be caught quicker; but at what cost? The effects of overfishing can lead to the extinction of not just the animals being fished, but also the predators that rely on fish to eat. Ninety percent of the ocean’s largest animals have been wiped out due to overfishing (“Overfishing- A Global Disaster”, 2011). National Geographic cites the academic journal Science (2006) that predicts by 2048, all fisheries will collapse due to lack of ocean wildlife. Fish are not the only animal caught in the nets used by fishing vessels. Often animals such as dolphins, sharks, turtles, and seabirds are

In 2009, Dr. Sylvia Earle wrote The World is Blue to educate and alert the reader about human impacts on marine ecosystems. Through this book she conveys her passion and methodical arguments concerning the importance of the conservation of the ocean, which encompasses approximately 80 percent of the earth’s surface. Dr. Earle states “the ocean touches you with every breath you take, every drop of water you drink, every bite you consume” (17). This statement emphasizes the significance of the ocean, not only for marine life, but all life forms on earth. The book implies that currently in today’s world, the conservation of the ocean requires a global effort to reduce human damage from the past generations. Using facts gleaned from credible scientific resources, she defines the problems of overfishing, bycatch, and pollution. By analyzing human impacts on marine ecosystems, Dr. Earle determines successful and unsuccessful solutions to these problems and suggests various ways individuals can change their lifestyles to reduce impact on the environment as a whole.

Modern fishing methods have first and foremost created serious problems for ocean ecosystems. Scholastic Scope states, “The populations of almost all fish species that we eat have shrunken, some drastically, as a result of overfishing, or catching fish faster than they can reproduce” (Dignan 14). Sadly, fish cannot reproduce fast enough to sustain their populations when different fishing techniques drain their ecosystem’s health. Because humans are relatively new organisms, fish, a much older species, have not adapted to modern fishing techniques and overfishing in the sea. Therefore, oceans are at risk because fish cannot compete with newer, more efficient fishing techniques produced by humans. Climate change is furthermore another major threat to oceans. As published by Scholastic Scope, “Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems” (Dignan 14). Although climate change may now be a controversial issue, its footprint and effects have no doubt left their mark. Powerful and destructive climate change has also been the culprit of extinction for many other animals such as the marine animals during the Permian-Triassic extinction event. Since things often repeat itself in history, the ocean could have a Holocene extinction event, which would completely

In comparison of David Allan’s masterfully sculpted Overfishing of Inland Waters to Myers’ vastly informative Rapid Worldwide Depletion of Predatory Fish Communities, the two contrasting writing styles embodied in the journal entries are blazingly evident. While each article shares the same postulation of mankind milking our oceans dry, the similarities stop there. One presents itself in circuitous manner and the other undeviating, not slowed by the baggage of excess verbiage. Regardless of the authors’ approach, each article contains largely similar evidence. The importance lies within the information: not presentation.

Overfishing is a threat not only to marine ecosystems, but also to human survival. If there are no fish, humanity will have to find alternative food sources, which, with our current technological capabilities, are not readily available nor easily accessible for the general population, potentially leading to widespread famine. Our advertisement highlights how soon this may become reality, with the statistical claim of scientists predicting the oceans to be completely lifeless by 2050. People may feel that our claim is more legitimate if it has been confirmed by professionals. The prediction alone is grim, and our choice to use the

Since the beginning of the human race, the ocean has been a major source of food. People near the shores have been taking of advantage of the ocean’s rich and diverse source of nourishment for centuries, both as a source of food and a livelihood. However, since the dawn of the industrial age, humans have begun to take from the ocean more that it can give. As a result, the ocean can no longer provide the human race with the abundance that it once did. As technology rapidly advances, populations skyrocket, and global warming spreads havoc, the ocean’s biodiversity and once abundant supply of fish is dwindling, calling marine scientists and experts to race to find solutions that will restore the oceans health while battling world hunger.

How often do we stop and think about the people that fish to provide the rest of the world with the supply of fish that is in demand. With many fisheries closing down due to poor managing and depletion, anglers are turning to the deep sea to fill their “fish orders”. Large fishing vessels also known as Super Trawlers are dragging fishing nets up to a mile deep. Doing this allows them to catch as many fish as possible, but it is also destroying natural habitat such as coral reefs that have been part of the sea for thousands of years. The effect of this is devastating to sea life.

It was Mihaljo Mesarovic, the author of “Mankind at the Turning Point”, who once said “The Earth has cancer and the cancer is man”. He was definitely onto something. In fact, humans have had a major negative impact on the world’s marine environment. Throughout recent human history, it has been obvious that the wellbeing of the marine environment has been in jeopardy. Pollution of the ocean, overfishing and the greenhouse gases these are all the aspects that can cause the destroying of the precious environments, such as reefs, sea-grass and coastal habitats. According to the essay and interview “Seafarming at the End of the World”, written by Peter Meehan, he presents the fact that human impact on the ocean is the main reason that causes the awful situation of marine ecosystem and organisms.

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

In some way or another, we all rely on the oceans to survive. They affect weather patterns, global temperatures, provide us with oxygen, all while removing carbon dioxide from the atmosphere. More importantly, they provide us with the food that sustains life. We have always relied on oceans for food. Fishing is not a new invention but in recent history, humans have exploited this source of food. We have had a chronic problem of over fishing, over harvesting the once bountiful supply of fish. According to a National Geographic report, “A study of catch data published in 2006 in the journal Science grimly predicted that if fishing rates continue apace, all the world’s fisheries will have collapsed by the year 2048 (Pristine Seas, National

The ocean is one of the largest sources of food and income for countries all across the globe. As the fishing industry and human population grow, more and more resources are being taken out of the ocean every year. If this process continues without any type of new regulation, our oceans’ supply of resources will quickly start depleting. Without a sustainable output from our oceans, millions of people will be losing income that they thought they could rely on forever. While most people are not aware of this problem, over the past fifty years overfishing has developed into a huge environmental issue that could have catastrophic global effects on us in the future if left untreated. According to WorldWildlife.org, ”More than 85 percent of the world's fisheries have been pushed to or beyond their biological limits and are in need of strict management plans to restore them”(WWL.org). This statistic shows that most of our oceans’ resources are being overused and depleted. Some of the the most important fish species, for example, the bluefin tuna, have been exploited to the point that their population’s survival is at risk. The overfishing of top predators disrupts marine ecosystems and food chains, leaving a large quantity of smaller populations. This type of imbalance can be very dangerous to the oceans ecosystems by throwing off the natural order of predators.
