Marine Biology Essays - Aquatic Ecology, Ocean Pollution

Marine Biology Aquarium Assignment A major source of coastal pollutants, human sewage fouls bays and beaches with both toxic and nontoxic pollutants. Although billions of dollars have been invested in sewage treatment plants to treat wastewater, new and growing coastal communities have increased the amount of discharge into oceans and estuaries. The United States Office of Technology Assessment has identified thirteen hundred major industries and six hundred municipal wastewater treatment plants that discharge into coastal waters of the United States. Many toxic substances enter the sea through the sewer systems, but others originate as industrial discharges. For many toxic substances, we do not yet know how to determine their extent or fate in the marine environment or to evaluate their effects on marine life. Some of the better-known trace metals and toxic chemicals include mercury, copper, lead, and chlorinated hydrocarbons. Chlorinated hydrocarbons, synthetic chlorine-containing compounds, are created for use as pesticides or are by-products of the manufacture of plastics. Oil is a very dangerous thing when it comes to oil spills into the ocean. These catastrophic oil spills engender a concern for the marine environment as no invisible containment can. Spilled oil floats on seawater and provides a constant reminder of its presence until it is washed ashore, sinks, or evaporates. Large volumes of oil suffocate benthic organisms by clogging their gills and filtering structures or fouling their digestive tracts. Marine birds and mammals suffer heavily as their feathers or fur become oil soaked and matter, and they lose insulation and buoyancy. Until recently, marine debris was considered to be of minor importance when compared to other pollutants. Problems caused by marine debris, however may rival or exceed those resulting from some better known pollutants, including oil. By definition, marine debris is any manufactured object discarded in the marine environment. When dumped, it may sink to the sea floor, remain suspended at mid-depths, or float at the surface and eventually be carried ashore by winds and waves. Plastics constitute as great an environmental threat as all the other kinds of debris, combined. Although plastics may break up into smaller pieces, they degrade much more slowly than most other kinds of debris, and most plastics float. Concentrations of plastics tend to be highest in the Northern Hemisphere, where vessel traffic is the heaviest, where most plastics manufacturers and fabricators are located, and where more intensive recreational use is made of beaches and coastal waters. Hopefully, as we approach the twenty-first century, we can learn to leave some old and wasteful habits behind. It will not be easy or simple, but each one of us must develop a sense of stewardship toward the world ocean and its

Narrative essay Essays (457 words) - Free Essays, Term Papers Narrative essay People say that what happens in movies do not always happen in real life. That those funny moments you see in television do not really happen to people. Well, with what I go through everyday, those funny and excruciatingly embarrassing moments really do happen. But there is one day in particular I would describe as the most unpredictable day. And it all started one fateful morning. As always i woke up late on a monday morning. As quickly as I could, I jumped in the shower and started clenching myself. I was in such a hurry that I accidentally inhaled my liquid shampoo, as soon as that happened; I instantly felt one of the worst pains I have ever dealt with my entire life. That kind of pain was unbearable to say the least; it made me cringe and whimper in pain. To relieve myself from the pain I inhaled some water and blew it out where a lot of bubbles came out. As I step out of the shower, I slipped on my soap and fell on my butt. Showering in a hurry really does have its advantages. I brushed off the pain I felt and washed myself again. I stepped out the shower more carefully, dried myself off; put on my colthes and went on with my day. As the day went on, more unfortunate events have happened to me. During lunch I almost tripped on a grade school student. It was a good thing that I caught myself on time or else nothing would have broken my fall except for the student I almost fell on top of. After lunch, as I was coming upstairs, a teacher caught up with me and told me that drinks were not allowed in the classroom. As if my daw wasnt bad enough already I had to drink my beverage outside the classroom. Alone. Dismissal finally came and I steel feel lika karma was chaseing me. As I was walking out of the main building, I almost got hit by a huge car. Thinking I was going to die that day, I saw my bad day flashed before my eyes and I was thinking of what I have done to deserve this way of dying. After that incident, I was scared of what more karma has in store for me today. When I got home, I finally found a time to relax after doing all my school works, I was randomly texting people until one of them texted me back, It was my happy crush and his reply to me made me forget about my very bad day. It really is true that every day may not be good but there is something good in every day.

If Crime is Normal why is so much Effort Devoted to its Control Essay

If Crime is Normal why is so much Effort Devoted to its Control - Essay Example Every human being has free will and free choice, they have the mentality to know right from wrong and they choose what path to take. This, from a sociological and psychological perspective is considered to be normal behavior in society. Thereby criminal intentions and actions are norms in the world even though they go against the very morals that societies have established. This is perhaps why law enforcement attempts to control and minimize these adversities even though they are everyday forms of existence as well. Again, even though crime is an existential part of existence, it is considered by many to be similar to a plague that has not been able to be washed away from society completely and therefore has remained for decades. Because of this many theorizations about crime have developed to analyze why it exists, why it has become something that is looked upon as normal, and what the causes of it actually are as well. Dolan, a criminological researcher, and writer (1994) claim that crime has become something so familiar in society, basically due to the classical socioeconomic causes of it. This can be traced as far back as the 15th century in England, when a crime was at times rampant and extremely violent, more so than it even is today. Crime in the 1500's took on the form of petty treason among servants and sometimes even the owners of these servants as well. From this it developed into more severe atrocities in society, sometimes becoming murder where the deceitful wife killed her husband as he slept, and even on to more dramatic forms of crime that took England by storm such as the crimes of "Jack the Ripper" (Valier 2003, pg. 34). The issues of crime in society are at times spell-binding and even terrifying as they take many forms and have the capability of taking place anywhere at any time, again placing them as a severe adversity in society, but quite normal activity among human beings all over the world.

This made the Taco Corporation to face the crisis of destroying brand reputation due to selling of tinted food known as Cry9c, which is harmful to human consumption.

Existentialism and Human Nature Essay Example for Free

Existentialism and Human Nature Essay Absolute individuality and absolute freedom: the basis of all existentialist arguments. The existentialists conceptions arise from their held views that since we are all ultimately alone, we have absolute freedom over our nature. Existentialists emphasize the free and conscious self which opponents constantly attack, exclaiming that there is a higher power enabling our consciousness. But are humans so simple? Can things be explained solely on blaming ourselves or another being for our nature? The existentialist generally believes in a sole existence; meaning that we are alone in the world, and that we have no one but ourselves. They also believe in the human beings capacity to feel more than one kind of pain, and that there are three different levels to our pain, physical, psychological, and emotional. All of these types of pain can cause us to become irrational and anxious. But are we really anxious because of this pain, or is it because we ultimately feel alone? And if we are all individuals, can we really feel the same kind of pain as someone else? Existence precedes essence is also dominant in the mind and thoughts of the existentialist. That is, the idea that we are born into this world without a predetermined nature, and only later in life do we shape out nature through actions and choices. This opposes the traditional view that is that essence precedes existence, according to which we are seen as having a purpose, and values, all of which is determined before birth. (I personally think that the idea of essence preceding existence is rather obscure. There is no way that our values and purpose can be determined by genetic code. DNA is what we are, not who we are. ) Existentialists pose another question to the opposition: how can we be happy in a world devoid of significance and meaning? The loss of external values allows us to derive value from within ourselves. This value is greater than any imposed by outside forces, and thus cannot be taken away from said sources. Although many human beings live a life devoid of true happiness, it does not mean that we are incapable of attaining such a goal. If a person finds the meaning for their life, whether it be one meaning, or many, there is a large chance that they can achieve such a utopia without recognizing outside influences. People of different viewpoints follow different methods, as well as believe in different forces that shape our nature. It is in my opinion, as well as that of the existentialist, that we shape our own nature through decisions and actions made by our own free will; that we are ultimately free to act independently from the influences of outside forces. That we can ultimately ignore the views imposed on us, and achieve a sustainable level of happiness in the process. Human nature is a frail thing; people are just looking for someone else to blame for their actions and for who they are, even when there isnt any. Therefore, there is no one to blame for who we are, but ourselves.

My Philosophy of Education :: Philosophy on Teaching Statement

Philosophy of Education As I have grown up in rural West Virginia, I have seen good education but I think I could possibly make it better. I also believe that rural areas have some of the best teachers. To some people, education is one of those easy careers that men and women choose to pursue because of the long vacations, the daytime hours, and the opportunity to sit behind a desk. To me, education keeps the teachers young by having the opportunity to be a mentor, a nurse, a friend, a coach, and many other things. My philosophical views are very eclectic. I know I will not have one style of teaching because I do not agree with exactly one. Many examples from each describe my future teaching methods. I am partial to the euphoric feeling I get when the teachers know you by name and you anticipate having those well-known teachers. I hope that in the years to come, I will be one of those teachers. I have not always wanted to be a teacher. Like so many people, I have changed my mind numerous times before I realized that teaching was the profession for me. I wanted to be a nurse for the excitement, and then I wanted to be a doctor for the money, then a veterinarian because I love animals, but I soon realized that I could incorporate the studies of each of these professions in my teaching. I also realized the science classes that I enjoyed in high school could make a great subject to teach as a career. Science is one of those classes I have found through my observations that the older children get, the less interesting it could be. It is a required subject in West Virginia for high school students to graduate and at least one class is needed to graduate in college. Even though it is required, the seniors and juniors are beginning to take lower level classes instead of higher level or advanced placement classes because they are easier. In younger grades, students get to experiment with things like bottle rockets, making crystals, and dropping eggs out of two-story windows to see if they will break. Upper grades technically in-depth and involve more note taking than experiments. When I teach science there will be days for lab, but notes will still be taken.
