A Green Machine in Man Essay

The Chesapeake Bay is a 200-mile-long estuary extending from Norfolk, VA to Havre de grace Maryland. On average this bay contains about 68 trillion liters of water. This bay is the largest estuary in North America. It inhabits more than 3,000 species of plants, animals, and fish. “Since the early twentieth century, the Chesapeake Bay has experienced serious environmental degradation. Problems include large reductions in sea grass, reduced amounts of finfish and shellfish (especially oysters and crab), seasonal depletions in dissolved oxygen, and increases in sedimentation.” (Atkins & Anderson, 2003) These changes are brought on by pollution (Eutrophication and Toxic Contamination), development, deforestation, and agriculture. And according

It is their home, their thriving place. According to the National WIldlife Federation, ¨The Bay supports 3,600 species of plant and animal life, including more than 300 fish species and 2,700 plant types.”. Not only does the wildlife depend on the bay, but humans do as well. The Chesapeake Bay contains a 64,000-square-mile watershed, this watershed provides large amounts of drinking water for us in Maryland, along with several other states. Everyday, the condition of the water declines, meaning the home for wildlife and our drinking water does too. The Chesapeake Bay Foundation pointed out that, ¨Toxic chemicals are constantly entering the Chesapeake Bay and its rivers and streams via wastewater, agriculture, stormwater, and air pollution. These harmful chemicals, such as mercury, PCBs, and PAHs, do not break down easily and persist in the environment for many years, impacting not just fish and birds, but humans as well.¨. How important does the restoration of the bay sound

Scientists and researchers began giving a large volume of effort and look into the extremely complex problems that face the Chesapeake Bay. When research for the improving and saving of the Bay’s overall health began it seemed very simple and there were only a couple of problems. The problems included nutrients from agricultural runoff; these nutrients were phosphorus and nitrogen. The combination of the nutrients in the Bay caused a large volume of algae that choked some of the marine life. While bringing in algae the nutrients also killed grasses on the seafloor. These seafloor bed grasses that once covered more than half of the Chesapeake Bay’s floor now only covered a tenth of their original area. Though the estuary was having problems it did not receive the terrible pollution from industries that many large rivers and lakes do in other urban areas (Brown, p. 397).

Types of human activity that affect the Bay's health. Humans either do not see or do not care about the pollution they send into the water. As humans build more factories close to the water or send more waste out of their homes it goes into the Bay causing many problems for the ecosystem. "waste from people's homes, stores, and offices is also treated and discharged into the Bay and its rivers. " (Chesapeake Bay Ecosystem) People do not understand the effects of pollution the Chesapeake Bay Ecosystem says that people believe the water where the pollution is going will dilute the pollution and won’t be as bad. Humans do no understand the problems pollution will cause. The population of the Blue Crabs in the Bay was below average for over 10 years. From 1998 until 2009 the crab ecosystem was so unhealthy they were unable to live and reproduce.

Ecology, the U.S. Department of Energy, and the U.S. Environmental Protection Agency as spelled out

The importance of the Chesapeake Bay is introduced. The bay is home to a large amount of seafood businesses, and many people fish the bay and its tributaries for sport. Grass beds are essential to many of the organisms living in this ecosystem, but are being destroyed by pollution. Agriculture involves more than a fourth of the bay's watershed. This makes agricultural runoff a big focus. Excessive nitrogen and phosphorus causes eutrophication. These nutrients come from pesticides and sewage also. A goal was set in 1985 to cut back the percent of nutrients being put into the bay by these two sources. It is thought that redirecting the flow of soil with nutrients in them will reduce the runoff, but if the nutrients seep into groundwater they still get into the Chesapeake Bay. Farmers have ways to help reduce these nutrient levels, but it is not the cheapest way to farm, so not all farmers are doing their part to save the bay. Another contributor of runoff land development. Runoff can occur from exposed land being prepared to be developed, or because of what has been used to replace what used to naturally be.

The bay has fifty major rivers and streams that drift into it. Nitrogen and Phosphorous are rapidly getting released into the bay. Most of the Nitrogen and Phosphorous comes from agriculture, air, and sewage. The excessive nitrogen and Phosphorus degrade the bay's water quality. Each year roughly three hundred pounds of polluting nitrogen gets into the Chesapeake Bay. Just like the Everglades the Chesapeake's water is in danger.

Nowadays, people stay away from analyzing how their actions impact the environment producing long lasting consequences. The opportunity to act is right where anyone stands and the closest one to this area is known as the Chesapeake Bay watershed. Therefore, the amount of nutrients going into the Chesapeake Bay should be reduced since the use of fertilizers has increased dramatically over time causing water pollution and the death of many species.

Technological developments have both created new opportunities as well as threats for the aviation industry.

i)The most important information that influenced Green & Co’s decision to enter the US market

Are computers going to replace the human thought? How many times do you see yourself going to www.google.com or some other search engine to find even the simplest information? In the educational system more and more courses use and require some form of computer activity. One of the main concerns is that education used to be about research, problem solving, critical thinking, and human analysis. Now with the implication of computers, education is not about the research, it focus is how fast can you find the answer. The lazy point and click approach may have the answers, but has no real meaning to it. Computers are taking away not only basic skills, but the need to develop them at all.

Enacted in 1972, the Clean Water Act was formulated with the goals of putting the end to the discharging of high quantities of contaminated materials into water resources, and further prevent pollution of water , and making sure that surface waters met the standards needed to support human and agricultural usage. Essentially, the Clean Water Act stipulates the fundamental structure used in the regulation of discharges of toxic pollutants into water resources of the US and ensuring conformance of quality standards for groundwater (Environmental Protection Agency). The Clean Water Act was draws based on the Federal Water Pollution Control Act of 1948, which was later developed and revised in 1972 to the Clean Water Act. Under the Clean Water Act, the Environmental Protection Agency (EPA) is authorized to implement programs to control pollution example being the establishment of standards for wastewater discharge for various industries. In addition, the CWA establishes the water quality standards applicable to all groundwater contaminants. The Clean Water Act makes it illegal to unload any contaminant material from a point source into navigable water bodies without acquiring permit from EPA. The National Pollutant Discharge Elimination System permit program, under the EPA, helps in controlling discharges (Environmental Protection

The green revolution is generally used to explain the application of modern, western-type farming techniques to less economically developed countries. The Green Revolution = == ==

The oceans of the world seem to be under attack from mankind and nature itself. Global warming is causing the melting of the polar ice causing the level of the oceans to rise. Garbage patches of plastic particles are floating in huge areas with some settling to the ocean floor. Acidification of the ocean water from fertilizer use is causing large so called dead zones where oxygen deprivation kills off plant and aquatic life. Many areas of the ocean have been dumping grounds for garbage, whether sludge like, solid, or chemical in nature. This paper will concentrate on the dead zones of the oceans, their causes, and the possible solutions to this problem.
