Fishing in the North Atlantic

Abstract

Ocean fishes have been consumed by humans beyond their maximum sustainable yields for years and the Atlantic cod and squid are two examples. Cods were primarily overfished to commercial extinction. Other variables were also examined to see if they contribute to the declining population. Water temperature was the natural phenomenon that may be responsible for poor egg hatching. Human causes such as increased UV radiation from depleted ozone and bottom trawling disturbance were considered. Trawling disturbance had the worst effect while the other factors were questionable. As the cod vanished, the commercial fisher turned to squid to continue their way of life. Government policy and economics had a great deal to do with the continuing overfishing pattern of wiping out one species and then turn to another. In the end, there is no real solution which accommodates both ecology and unchanged societal uses at the same time.

Introduction

It was believed that 500 years ago, Irish settlers went to Newfoundland not for the religious freedom there, but the fertile fish banks near the shore(Pollack, 1995). This was all but history now. The overfishing crisis took on headlines back in the early 1990s. The fish pack waters in the north Atlantic were rapidly removed for profit until the fish population was decimated. The current seafood production and human dependence upon it are enormous. In many third world countries, seafoods are the primary source of protein for human consumption. According to the offical website of the Commerce Department's National Oceanic and Atmospheric Administration, the seafood consumption in the U.S. remained steady with Americans consuming 3.90 billion pounds ...

  • The Existence of ADD and ADHD

    4006 Words  | 9 Pages

    While the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) of the American Psychiatric Association) put forth a list of behaviors which predominantly fall in the category of ADD and/or ADHD, many researchers still maintain that there is no set way to diagnosis or develop a treatment program to these disorders which will be guaranteed to work. At the same time there is another set of researchers who maintain that these disorders actually do not exist at all. However, in the real world, parents and educators still continue to struggle with the task of coping with children who are hyperactive and who have very low attention span and whose behavior often interferes with schooling and family life.

    Attention Deficit Disorder (ADD) is a problem that affects 5% to 10% of all children. ADD affects more children than any other childhood problems except asthma. It is estimated to be the largest single cause for first referrals to child guidance clinics throughout the country, making up as many as 40% of those cases. Many ADD cases are not diagnosed because the problem most often does not show in the doctor’s office.

  • Egnisia And Religion: The Views Of Euthanasia

    2210 Words  | 5 Pages

    ​Euthanasia is and will always be one of the leading ethical issues present in the world. There are strong arguments present on both sides of the issue including that of one of the most influential institutions on the planet; the Catholic Church. The Church has, and always will be against the killing of a human being. This applies to euthanasia: “An action or omission which of itself and by intention causes death, with the purpose of eliminating all suffering.” (Pope John Paul II - Evangelium Vitae). The Church also refers to euthanasia as “assisted suicide” and the “mercy killing”. “Whatever its motives and means, direct euthanasia consists in putting an end to the lives of handicapped, sick, or dying persons. It is morally unacceptable. Thus an act or omission which, of itself or by intention, causes death in order to eliminate suffering constitutes a murder gravely contrary to the dignity of the human person and to the respect due to the living God, his Creator. The error of judgment into which one can fall in good faith does not change the nature of this murderous act, which must always be forbidden and excluded.” (Catechism of the Catholic Church – 2277).

  • Symptoms of ADD/ADHD

    1055 Words  | 3 Pages

    You know that person; the one that can’t stay on subject, the one who will be talking then all of a sudden the conversation goes off in a totally different direction, like a squirrel searching for nuts that keeps dropping the one it is carrying because something else caught its eye. Chaotic, frazzled, impulsive, unorganized, daydreamer, procrastinator, inattentive, goof off and lazy are just a few descriptions of an adult that has Attention Deficit Disorder/Attention Deficit Hyperactivity Disorder (ADD/ADHD). At one time ADD/ADHD was thought of as just childhood complications that did not affect adults, but since there is no cure for ADD/ADHD, adults are affected also. Most adults that have ADD/ADHD were not diagnosed with it as children, because ADD/ADHD wasn’t recognized except by a very few people that were aware of it at the time (Smith and Segal, 2012). Instead as children they were labeled as lazy, trouble makers, day dreamers and other labels and they grew into adults with those same labels and tendencies. They may have learned to adjust during the teen years but as they became adults and responsibilities and demands on their time grew, the challenges of dealing with ADD/ADHD also grew. ADD/ADHD affects 4-5 percent of all adults, more than 11 million in the United States (Barkley). When not diagnosed and treated it can impact all areas of life including work, home and social relationships. With treatment adults, and children, with ADD/ADHD can learn to compensate and overcome the symptoms and challenges they face with ADD/ADHD on a daily basis to lead productive lives.

  • Attention Deficit Hyperactivity Disorder (ADHD)

    1014 Words  | 3 Pages

    Attention Deficit Hyperactivity Disorder (ADHD), more commonly referred to as ADD (Attention Deficit Disorder), has only recently come to notice of scientists. It affects 3.5 million people under the age of 18 and 5 million people over the age of 18. Its current cause of existence is due to defects at neurotransmitter sites, rendering patients inattentive and impulsive. However, every year more progress is made in locating the cause and finding more effective treatments. ADHD's first diagnosis was made in 1902 by Dr. George Still. He observed 20 children who were inattentive, impulsive, hyperactive, and showed mood swings. He initially attributed their behavior to mild brain damage. By 1917 ADHD or constantly active was still thought to have this cause. At this time, viral encephalitis seemed to be linked to the disease because, after being infected, children had impaired attention, memory, and impulse control. In 1937 ADHD was known as minimal brain dysfunction and began to be treated with amphetamines, which made children with the disorder much calmer.

    ADHD is broken into three subtypes. The first is those who are impulsive and hyperactive. The second type is made up from those who are inattentive only. The third group is those who display all of these symptoms combined. In the United States, 3-5% of children show signs of this disorder. It has also been shown that the disorder is more dominant in boys. Many children with ADHD do not outgrow this disorder and carry it on into their adult lives. Various studies have shown that two-thirds of children with ADHD still have the disorder in their 20’s making it is a problem which affects children and adults alike.

  • A Debate On Euthanasia

    1954 Words  | 4 Pages

    Before discussing the way the Catholic Church has responded to the topic of euthanasia, it is important to understand what euthanasia truly is. Euthanasia comes from two Greek works: eu which means good and thanatos which means death. These terms come together to mean “good death”, referencing the common practice of voluntary suicide by old or sick people who wish to have a painless death by drinking the poison hemlock. The term euthanasia has assumed several dimensions throughout history. During the 17th century the term came to explain actions taken by a physician to reduce pain in dying patients, associated with assisting in death or suicide. In ...

  • The Effects of Overfishing on the Restaurant Industry

    1580 Words  | 4 Pages

    To fish or not to fish is a personal choice. The fact that the oceans are being overfished is a growing concern for individuals, organizations, and governments throughout the world. In this paper I want to discuss the effects of overfishing on the restaurant industry, and possible solutions to solve the problem. Fishing is an ongoing source of food for people around the world. In many countries it is a food staple in their everyday diet. In more modern societies eating fish has become a sensual experience, and not just for the wealthy. It hasn't been until population explosions in the last century that the demand for seafood has led to more effective fishing techniques and technologies. Now the demand for popular fish like the salmon, tuna, sea bass, cod and hoki, which is the key fish in McDonalds filet o' fish, is diving wild populations to dangerously low levels. The methods used to catch the amount of fish demanded by the industry do not leave sustainable populations in the wild. In an attempt to preserve the fish population, governments have set limits on the minimum size that may be harvested and how many of each may be taken. Boundaries have been set up saying which areas can be fished and which ones should be left alone. A number of smaller fisheries have gone out of business because of the limits imposed by the government. This leads to even less fish being harvested and brought to market. Therefore the amount and varieties of fish at markets are smaller and can cause shortages for wholesalers and restaurants. Some restaurants will no longer have the variety on their menus that they used to enjoy. If a restaurant thrives on its seafood menu they may be unable to cope with the shortages and will go out of business. In the ...
