Storm Water Runoff and the Chesapeake Bay Biology 181
The Chesapeake Bay was the home for our first settlements, and today is the source for much of the oysters, crabs, clams and other seafoods for the Atlantic Coast. The Chesapeake Bay is the largest estuary in the United States, and the largest on this entire continent! Being an estuary is that tidal area where ocean water and fresh water and their inhabitants mingle and coexist. In reality the Bay is the heart of a beautiful, productive and diverse natural environment. It lays one half in Maryland and the other half in Virginia, but it’s shores touch Delaware and its tributaries span 64,000 square miles along the Eastern Seaboard from New York south to the inland bays of the Carolinas.
The Chesapeake Bay is a topic that is dear to me. My family comes from a long line of fishermen in the Northern Neck of Virginia, who had to end their way of life in the 1940\'s because of the pollution to the water, and it\'s reduction to the numbers of animal life in and around the Chesapeake Bay. The problem hasn\'t gotten any better since then, only worse. Charles Wood is my mother’s father and started his career as a fishing boat engineer in the late 1800’s. The Chesapeake Bay that my grandfather Charles Wood used to fish was a wonderland of wall-to-wall oysters, and the fishing boats and ships had trouble steering around them. My mother tells me stories of growing up on the water, and how abundant and fresh all of the seafood was back then. They could fish right from their backyard during summer months for blue crab, and all species of fish.
Seasonal harvests of oysters in the Chesapeake Bay in the 1700’s were once in the millions of bushels. Oysters consume algae and other water-borne nutrients by filtering water at a rate of up to five liters per hour. Because they exist on the bottom of the Bay among the silt, the Bay’s once-flourishing oysters acted as a natural filter for the water system. Scientists estimate the oysters were able to clean our estuary’s entire water volume of excess nutrients every three or four days!
The Problem with Storm Water Runoff
The Chesapeake Bay is also the largest producer of crabs in the entire USA. In present times, with algal blooms in over abundance and eutrophication on the rise, we are experiencing a dramatic decline of oysters, and the degradation of our estuary is even more rapid. Decreased crab and oyster abundance is just one sign that our estuary’s future health is looking bleak. The cancer mortality rate in Maryland is among the highest in the United States, ranking the seventh highest. Fish in the Anacostia River in D.C. have cancerous tumor rates that are as high as ever documented in an American river, and a U.S. government-led study to be published next month will positively link the tumors to pollution caused by vehicle emissions and runoff.
The Pew Oceans Commission is an unbiased group of leaders who were assembled to investigate the condition of our Earth’s waters. The Pew report, which is the most thorough and focused report on the state of the World’s oceans in 35 years, summarized its research on the state of the world’s oceans and waterways in a comprehensive report. This report opened a lot of people’s eyes to the unbelievably poor condition of our waters. (I would recommend that every single American read that report; it affects us all, and a lot of the information is shocking.) The Pew report shows among many other topics, that as more and more people move towards coastal areas, water pollution problems will increase, and the delicate balance of life in the Chesapeake Bay will be stressed to the brink. The Environmental Protection Agency in its National Coastal Condition Report issued in September 2001 labeled the country’s coastal environment as ranging from fair to poor condition. That was back in 2001!
With Washington, D.C. being at the heart of the Chesapeake Bay, all visitors and inhabitants of that city contribute to the Bay’s poor health. The Anacostia River is like a sink that collects everything that ends up on the streets. That includes pollution

Auschwitz Auschwitz Auschwitz began as a barracks camp in the town of Oswiecim, for the polish army in the early 1930's. Germany then captured Poland and needed another location for Polish political prisoners. In 1940, the German SS sent a commission to Oswiecim to see if the barracks there could be used. The first inspection reported that it could not be used, however, a later inspection stated that after a few minor changes it would be useable. On May 4, 1940 Rudolf Hoss officially established it as a

OverpopulationOverpopulation By: Eric Krause Do you feel that all humans have the right to enjoy natural beauty? The right to decent, uncrowded shelter? The right to eat healthy food and drink pure water? To breathe clean air and avoid pesticide poisoning? Most people would say every human has a right to all of these things, but in some areas of the world these rights are not being met. Most species have a sideways S shaped graph reflecting growth rate, meaning the species will go up in total population but

It is having disastrous effects on our environment. There are too many implications and interrelationships to discuss in this paper, but the three substances that our earth consists of: land, water and air, are being destroyed. Our forests are being cut down at an alarming rate, bearing enormous impact
Acid Rain LegislationAcid Rain Legislation Acid rain is a destructive force as a result of nature and man colliding. It is formed through harmful industrial emissions combining with contents of the earth's atmosphere; a dangerous combination. This prompted governments throughout North America to take action. Many laws and regulations have been implemented, yet the question still remains, Should tougher legislation be implemented to force industries to reduce acid rain emissions? To decide whether tougher legislati
Acid RainAcid Rain Acid rain forms when sulfur and nitrogen dioxides combine with moisture in the atmosphere to produce rain, snow, or another kind of precipitation. This kind of pollution may also be suspended in fog or deposited in a dry form. Acid rain is most common in North America and Europe. Acid rain has also been detected in other areas of the world such as tropical rain forests of Africa. Canada has placed limitations on the sulfur emissions. The United States has not, so the emissions may stil
ACID RAINACID RAIN When fossil fuels such as coal, gasoline, and fuel oils are burned, they emit oxides of sulfur, carbon, and nitrogen into the air. These oxides combine with moisture in the air to form sulfuric acid, carbonic acid, and nitric acid. When it rains or snows, these acids are brought to Earth in what is called acid rain. During the course of the 20th century, the acidity of the air and acid rain have come to be recognized as a leading threat to the stability and quality of the Earth's envir
Acid RainAcid Rain As the century past, the industrial society kept advancing. However, many advantages of the industrial society brings us also has a down side. One of the adverse effects of industrialization is acid deposition due to power plant, fossil fuel and automobile emissions. Acid rain is the popular term but the scientists prefer the term acid deposition. Acid rain can have adverse effects on the environment by damaging forests or by lowering the pH of the lakes and making the water too acidic
Problems Caused By Air PollutionProblems Caused By Air Pollution Some people think that air pollution is not harming the earth or the people, but it is doing worse, by killing the earth and getting people sick. Air pollutants, according to Gay, are known to cause respiratory diseases, cancer, and other serious illnesses (12). Air pollution not only threatens the health and life of humans but also causes damage to the environment (Gay 13). First, air pollution causes a great deal of health problems. Wanting clean air is a g
AIR POLUTIONAIR POLUTION Problem The first thing people see, in the morning, when they walk outside is the sky or the colored sun. Is this world giving us the privilege of seeing the natural colors of the sun through all the layers of pollution within the air (Dinanike 31)? Not only are beautiful sights such as this hidden behind the pollution this world causes everyday, but an increase in diseases, infections and death occurs. What causes pollution? What can we do to prevent it, and get rid of it? Is it fa

(GutterMouth; Nitro Records; 1995) In 1948, the industrial town of Donora, Pennsylvania suffered 28 deaths because of the thick smog. Air pollution is an ecological problem having to do with toxins in the air. There are a few things the human race has done to try to prevent air pollution from taking such a serious toll. Two of these are the Clean Air Acts and the increased use of solar power over coal po
Animal EthicsAnimal Ethics Animal ethics is concerned with the status of animals, whereas environmental ethics concerns itself with the relationship to the environment. I will show the existence of animal ethics depends on the existence of environmental ethics. I will prove this by showing that such philosophers who have practiced animal ethics such as Singer, Regan, and Taylor are limited because they are individualistic. Which means they are limited to animal concerns, and nothing else. But with the enviro
BIODIVERSITYBIODIVERSITY Biodiversity, as defined by E.O. Wilson, is meant to be all inclusive- it's the genetic based variation of living organisms at all levels, from the variety of genes in populations of single species, through species, on up to the array of natural ecosystems. This includes plants, animals, insects, fungi, bacteria, and all microorganisms. All of these things create what is known as a web. These things interact with each other in some way there for they depend on one another throug

Lately the earth's capacity to tolerate exploitation and absorb solid wastes disposal has diminished, due to excess trashing. People dispose lots of stuff, and simply do not care. Therefore scientists found out a way to reuse things and that process was called recycling. This new approach seemed quite successful at the beginning, until its true identity appeared. Recycling first started as man
Chinook SalmonChinook Salmon Environmental Science Wednesday, February 26, 1997 Among the many kinds of fish harvested each year by commercial fisheries is the Oncorhynchus tshawytscha or Chinook salmon. The United States catches an averages of about three hundred million pounds of salmon each year. However some Chinook salmon have been recently listed as threatened. Man has been the main cause for the decline in Chinook salmon populations. The populations of Chinook salmon have declined for several reasons.
Preserving Our EarthPreserving Our Earth America's endangered areas are deplinishing daily. Natural disasters are a major factor in their disappearance, but the most prominent factor is mankind. Even though procedures are conducted daily to preserve our home, these areas slowly crumble within our grasps. Protection of these areas is essential, as our whole race depends upon resources derived from these lands. From the lush greenery to the sparkling blue waters, all is majestic in its fullest. This is why I believe
EstuariesEstuaries An estuary is a coastal area where fresh water from rivers and streams mixes with salt water from the ocean. Many bays, sounds, and lagoons along coasts are estuaries. Portions of rivers and streams connected to estuaries are also considered part of the estuary. The land area from which fresh water drains into the estuary is its watershed. Estuaries come in all shapes and sizes, each unique to their location and climate. Bays, sounds, marshes, swamps, inlets, and sloughs are all exampl
ManateesManatees Quietly, but swiftly, the plump, dark animal glided across the water while making sounds comparable to that of the squeaks and squeals of a whale (Florida Manatee 1). Some would say these aquatic mammals are the ugliest thing below the surface, others would say that these animals are beautiful and resemble portly mermaids, but no matter what anybody says about the manatees, they are unique creatures (Ray and Ciampi 315). They are mammals that are completely harmless, they feed mostly
OceansOceans The ocean covers Seventy-one percent of our planets surface. Life is concentrated, however, in about four percent of it, and it is this four percent that is being polluted by the tons every day. Everyone needs to understand that the oceans are not endless, and not bottomless. They also much see that the ocean contains much marine life which are essential to our eco-system. And in order to preserve this other world of life, we must stop polluting the oceans, and begin to clean them up. Alt

An Ecosystem's Disturbance by a PollutantAn Ecosystem's Disturbance by a Pollutant Paul Cordova L. Lehr December 11, 1995 Freedman defines a pollutant as the occurrence of toxic substances or energy in a larger quality then the ecological communities or particular species can tolerate without suffering measurable detriment (Freeman, 562). Although the effects of a pollutant on an organism vary depending on the dose and duration (how long administered). The impact can be one of sublethality to lethality, all dependent upon the factor

This blanket silences the expected sounds of the wetland environment, birds chirping, ducks splashing, insects buzzing and animals thriving. This unnatural silence is disturbing, the favourite flowers that used to litter this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy pur

Solar Energy An Alternative EnergySolar Energy: An Alternative Energy Imagine a perfect source of energy. One with which no pollution what-so-ever is associated with. No poisonous gasses or destruction of rain forests. This abundant source of energy comes from the sun. Solar energy is the visible energy produced in the sun as a result of a constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared.

The Greenhouse EffectThe Greenhouse Effect This essay is going to describe what the greenhouse effect is and what it does.It is also going to say what causes the greenhouse effect and the consequences of it. What is meant by the term the greenhouse effect is that the heat from the sun comes into the Earth's atmosphere and cannot get out so becomes trapped.It gets its name because this is very much like a greenhouse.This effect occurs as the incoming short wave radiation is changed when it hits the Earth's surface in
Urban Heat IslandsUrban Heat Islands For more than 100 years, it has been known that two adjacent cities are generally warmer than the surrounding areas. This region of city warmth, known as an urban heat island, can influence the concentration of air pollution. The urban heat island is formed when industrial and urban areas are developed and heat becomes more abundant. In rural areas, a large part of the incoming solar energy is used to evaporate water from vegetation and soil. In cities, where less vegetation a

These plants all have their roots in soil covered or saturated with water and its leaves held above water.Marshes may be freshwater or salt. Freshwater marshes develop along the shallow edges of lakes and slow-moving rivers, forming when ponds and lakes become filled with sediment. Salt marshes occur on coastal tidal flats. Inland salt marshes occupy the edges of lakes. They affect the supply of nutrients, the movement

Keep Our Water Clean Clean Water ActKeep Our Water Clean: Clean Water Act The Clean Water Act has made advances to our society that have helped our environment to flourish with life. The objective of the Act when it was enacted in 1972 was to restore and maintain the chemical, physical, and biological integrity of the Nation's water. This objective was accompanied by other statutory goals to eliminate the discharge of pollutants into waters used by boats by 1985 and to attain waters deemed “fishable or swimmable” by 1983. So far,

The United States political system has been historically anthropocen-tric, or human centered. Environmental groups have been attempting to change this to a biocentric or ecocentric viewpoint, which includes the rights of animals and the environment. These views are nature centered instead of human centered. This stu
The Government and Environmental PolicyThe Government and Environmental Policy The purpose of the United States' public policy law is to implement restrictions in an effort to solve problems, which can be seen with the Clean Water Act. Public policy has also been employed to reform the Endangered Species Act of 1973. Although the United States government is noble in it's efforts to preserve the environment through these acts, the internal structure of public policy often retards these acts' effectiveness. This paper will explore the

The Greenhouse EffectThe Greenhouse Effect The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. ÂłThe glassÂ˛ lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methan
Crime in culturecrime in culture Crime refers to many types of misconduct forbidden by law. Crimes include such things as murder, stealing a car, resisting arrest, possessing or selling illegal drugs, appearing nude on a public street, drunken driving, and bank robbery. The list of acts considered crimes is constantly changing. For example, at one time, people were charged with witchcraft, but this is no longer illegal. Today, it is becoming a serious crime to pollute the air and water. In colonial days, pollut
