Introduction
The Chesapeake Bay is a large estuary located on the east coast of the United States. The bay is over 200 miles long and goes through Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia. The bay has much to offer the locals. Many locals have made a career out of harvesting the bay's sea food. The bay's harvest and many of its other attractions bring tourists and in turn revenue for the area. Oysters and blue crab are a big part of the culture in the bay area. However, these organisms are in danger and need help.
Description of the problem
Eutrophication is a concern in the Chesapeake Bay. Eutrophication is caused by excessive amounts of nutrients. Excessive nutrients in the bay have negative affects on

This can be misleading. The bay takes up a large part of land but it is not very deep and does not contain much water. This makes the bay vulnerable to pollutants because there is not much water to dilute them.(Runoff and the Chesapeake Bay) Most of the excessive nutrients in the bay come from agricultural run off. For example, Lancaster County produces more than ten billion pounds of manure annually. When the manure is not handled correctly the nutrients are washed into tributaries of the bay. Often too much manure and fertilizer is applied and the excessive nutrients find their way into the bay. Even when precautions are taken to keep excessive nutrients out of the bay they seep into the groundwater and pollute the …show more content…
For many years now scientists and researchers have been paying their attention to the bay. Millions of dollars and hundreds of hours have been spent to return the bay to its glory. However, with all that has been done the bay is still in danger and the work is no where near complete. In 2005 the bay's health was evaluated at a “D”. (Chesapeake Bay Restoration) That is not ideal for a project that has been trying to restore the bay since the 1980s.
Many people can not seam to comprehend what is going on within the bay. The money and time has been spent many answers have been found and solutions are ready to be put into place so what is the hold up? One factor is the lack of responsibility assumed by political leaders. In 1984 legislation was signed by political leaders that began the restoration of the bay. The problem is that there are no great consequences if the requirements established by the legislation are not met. As a result ninety percent of the bay's waters are in violation of the legislation and no one is being held responsible. (Bay Agreement Efforts Are Foundering) If the people running this country can not be held responsible than how can we expect everyday citizens to do their
silence. Living from “hand to mouth” induced the gold miners to only be able to
cut back on the problems in the Bay. Scientists have given an unthinkable amount of attention to the Bay of the past several years and researchers from countless numbers of agencies and institutions have dove deep into the issues and studying every nook and cranny to create answers to every politicians’ questions. The biggest concern with the Bay, and the most concentrated ...
One of the Bays biggest resources is its oysters. Oysters are filter feeders which mean they feed on agley and clean the water. The oysters feed on agley and other pollutants in the bay turning them into food, then they condense the food down to nutrients and sometimes developed pearls. Filtering the water helps the oysters to grow, and also helps clean the Chesapeake Bay. One oyster can filter 50 gallons of water a day, Oysters used to be able to filter the Bay in about a week. However, these creatures are now scarce in the bay. The Chesapeake Bays Oyster (crassostrea virginica) Population has declined severely because of over harvesting, agricultural runoff, and disease. Now the Chesapeake Bay is becoming polluted without the oysters and the water is not nearly as clean as it once was. The Chesapeake Bay was the first estuary in the nation to be targeted for restoration as an integrated watershed and ecosystem. (Chesapeake Bay Program n/d). This report will show the cause and effect of the Chesapeake Bay's Oyster decline on the Bay.
The Maryland Blue Crab is an essential part of the Chesapeake Bay; from the food chain of the creatures in the water, to the business side of the thriving demand for the crab during the hot summer months, but there is no denying the fact that the crab is just as important alive as it is when it is being harvested by local fisherman. By becoming more informed of the impact the crab has on Maryland’s bay and on the people who live around it, people can take bigger steps in making sure the crab will always be around for decades to come.
The Long Island Sound is an estuary, and is in fact one of the largest in the world. An estuary is a place where salt water from the ocean mixes with fresh water from the rivers that drain from the land. Moreover, like other estuaries, the Long Island Sound has an abundance of fish and other waterfowl that add to the natural balance of the island, as well as one of the most important economic factors (Tedesco). Like other estuaries around the world, the Sound provides breeding, feeding, nesting, and nursery areas for many species that will spend most of their adult lives in the oceans (Long Island Sound Study). Despite these similarities to other estuaries, the Long Island Sound is unique from anywhere else in the world. Unlike other estuaries, the Long Island Sound does not just have one connection to the sea but it has two. It has two major sources of fresh water flowing into the bay that empty into the ocean. It combines this two-...
The Chesapeake Bay is the nation’s largest estuary with six major tributaries, the James, the Potomac, the Susquehanna, the Patuxent, the York, and the Rappahannock Rivers, feeding into the bay from various locations in Maryland, Virginia, Pennsylvania, and the District of Columbia (Chemical Contaminants in the Chesapeake Bay – Workshop Discussion 1). These areas depend on the Bay as both an environmental and an economic resource. Throughout the last 15 years the Chesapeake Bay has suffered from elevated levels of pollution. Nitrogen and phosphorous from wastewater treatment plants, farmland, air pollution, and development all lead to reduced water clarity and lowered oxygen levels, which harm fish, crabs, oysters and underwater grasses (Key Commission Issues 1). There are other types of pollution in the bay such as toxic chemicals, but because nutrient pollution is the most significant and most widespread in the Bay its effects are the most harmful to fisheries. Nitrogen and phosphorous fuel algal blooms which cloud the water and block sunlight from reaching underwater grass beds that provide food and habitat for waterfowl, juvenile fish, blue crabs, and other species (Blankenship 11-12). Algae plays a vital role in the food chain by providing food for small fish and oysters. However, when there is an overabundance of algae it dies, sinks to the bottom of the Bay, and decomposes in such a manner that depletes the oxygen levels of the Bay (11). The reduced oxygen levels in the Bay reduce the carrying capacity of the environment and these “dead areas” sometimes kill off species that can not migrate to other areas of the Bay, such as oysters (11). Increased abundance of algal blooms also led to the overabundance of harmful and toxic algae species and microbes such as the microbe Pfiesteria, which was responsible in 1997 for eating fish alive and making dozens of people sick (12). The heightened awareness of diseases that can be contracted through consumption of contaminated fish also has an economic impact. Therefore, the excess levels of nitrogen and phosphorous have fueled an overabundance of algal blooms, which has reduced water clarity and lowered oxygen levels, affecting many species within the bay and ultimately the industries that rely on these species.
The Chesapeake Bay is a large bay that stretches from Maryland to Virginia, fed by many rivers and streams that run from as far north as New York to Virginia and West Virginia.5 It is home to a plethora of plants and fish species, many of which the people of the area fish for food and supplies. The pollution present in the Chesapeake Bay is affecting the livelihood of both the fishermen and the fish – the less the fishermen haul due to the death of the species they catch, the less they get paid – and as consumers of these fish, we are consuming the toxins as well.

The non-profit organization that I researched is the Chesapeake Bay Foundation. They have spent the last 40 years educating people who live near the Chesapeake Bay or near one of its tributaries on things that need to be done in order to create a safe habitat for the aquatic and terrestrial life living near these waters and creating healthier, cleaner water within the bay.
According to NOAA phytoplankton are microscopic organisms that continuously convert sunlight and nutrients into living tissue. Phytoplankton can be harmful to the bay because they at an uncontrollable rate causing harmful algae blooms when there is an abundance of nutrients. Phytoplankton also serve as the main food source for a larger but still microscopic organism named Zooplankton. Marine Bio.org did a study on zooplnkton revealing that they are very weak swimmers making them an easy food source for any larger organsim. Zooplanktons’ main purpose serves as the main food source for small fish and
I feel that there is progress happening everywhere in the world today. Not all progress is from new advancements in science and technology but a lot of it is. There is so much knowledge held amongst people to allow such advancements to occur. Having knowledge is a great tool because without it, there would be no progress of any sort. People need to learn that they should study as much as possible so maybe one day they can contribute to making more progress happen. Achieving progress is a helpful way of improving our standard way of living. Even though progress is a good thing, I also feel that it can cause problems too. People just need to realize that in order to produce new and better things we might have to go through some rough times on the way. New advancements will continually be arising in the future and hopefully somebody one day will find away to make it so these new advancements will not contain new problems.
The Chesapeake Bay is a very large estuary that holds more than eighteen trillion gallons of water (“The Bay Watershed”). This large estuary is part of six of the different states of Maryland, Delaware, New York, Pennsylvania, Virginia, and West Virginia (“Chesapeake Bay Program”). Some characteristics of the bay are salinity, temperature, and circulation. The bay watershed is home to seventeen million people and gains more people each year, so it is no wonder why there are pollution problems (“Chesapeake Bay Program”). The Chesapeake Bay is the largest estuary in the United States and is diverse with life. Though the bay is filled with life, it faces many problems caused by humans.
Being found in a Mid-Atlantic state but south of the Mason Dixon line Maryland can lay claim to a blend of Northern and Southern American traditions. Maryland has been influenced by English, American, and African American cuisine. Seafood is a prime ingredient in Maryland cuisine and is also the state's primary food product. Harvesting seafood in the Chesapeake Bay dates back to the Indians. Many Indians preserved their catches for winter by salting or smoking them. Chesapeake Bay oysters have been eaten for centuries. The Patuxent River has been an importan...
Looking at the early English colonies in the Chesapeake Bay region, it’s clear that the English had not learned any lessons from their experiences at Roanoke. Poor planning, a bad location, unrealistic expectations, flawed leadership, unsuccessful relations with the local Indians, and no hope of finding the mineral wealth the Spanish found in Mexico, all contributed to failure. The first colonists in the Chesapeake region were not only ignorant, lazy and unambitious, but their attempts were hampered before they had begun. However, a solution to these problems was found in a single plant: tobacco. Nevertheless, this cash crop ultimately created numerous problems for the colonists. The ignorance and indolent acts of the Chesapeake colonists to unsuccessfully restore the colony by themselves led to the demise of the colony as a whole especially regarding the planting of agricultural goods for food.
The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
