Marine Ecosystem
Out of all of the large and natural resources available for generating electricity in the United States, it is the ocean. Ocean energy may be the last investigated for its potential. The ocean is so vast and deep, until recently, it was assumed that no matter how many chemicals or how much trash humans dumped into the ocean, the effects would be negligible. Dumping into oceans have even got the catchphrase: “The solution to pollution is dilution” (National Geographic, 2013) Impacts Associated With Agriculture
Pollutants from agriculture have affected the marine’s ecosystem in ways that may not be reversible, and may also be slowly harming rivers, streams, and coastal waters. Pesticides and fertilizer are two major components that have disturbed the marine’s ecosystem; both contain harmful chemicals that can be hazardous to living organisms in the water. Fertilizer and pesticide run-off from large farms may have initiated bursts of marine algae which may disrupt the ocean’s ecosystem by causing massive blooms in marine waters (Schwartz, 2005). Winds cause nitrogen and other nutrients from the seafloor to surface, which promote the growth of algae called phytoplankton. Phytoplankton is a main source of food for many living organisms in the marine waters. Agricultural pollutants may have triggered phytoplankton to produce harmful blooms in tides, which are giving-off poisonous toxins to marine life. These poisonous toxins are dangerous because the oxygen levels are gradually diminishing in waters, which may have deadly consequences for marine life (Schwartz, 2005).
Aquaculture is the farming of aquatic organisms such as fish, shellfish, and even plants. The term aquaculture refers to the cultivation of both marine and freshwater species and can range from land-based to open-ocean

...of the Environment & Natural Resources The country is widely acknowledged as having an outstanding endowment of natural resources, which could provide essential ecosystem services to the population. Demands arising from development and utilization activities, population expansion, poor environmental protection, and external factors such as climate change, however, have placed the country’s environment and natural resources under grave threat. For the medium-term, an environment that is healthy, ecologically balanced, sustainably productive, climate change resilient, and one that provides for present and future generations of Filipinos is envisioned. This vision will be pursued through an integrated and community-based ecosystems approach to environment and natural resources management, precautionary approach to environment and natural resources, sound environmental impact assessment (EIA) and cost-benefit analysis (CBA). These, then, are all anchored on the principles of shared responsibility, good governance, participation, social and environmental justice, intergenerational space and gender equity, with people at the core of conservation, protection and rehabilitation, and developmental initiatives. Assessment State of the Environment and Natural Resources The degraded state of the country’s environment and natural resources is felt most intensely by the poor, especially the rural communities given that they depend on these resources for their primary source of...

...Activities Involved In the Conservation of Natural Resources Introduction The energy consumption of western cities' households stands at about one-third. Energy is a very good example of a natural resource. In as much as it is surprising, efforts have been made since the 21st century to try and conserve these natural resources (Montana Conservation Council, 1956, p. 12). The essay seeks to discuss how some of the activities carried out have been used to promote resource efficiency and sustainable management of natural resources. The essay seeks to detail information on some of the case studies depicting the impacts of these activities. Promotion of Energy Efficient Bulbs The energy efficient bulbs are energy economical due to its insignificant consumption of electricity. According to the results obtained by conducting a series of tests, the bulb converts about 80 percent of the electrical power to light energy. The other 20 percent is therefore converted to other forms of energy such as heat. When compared to traditional bulbs, the results were opposite to having 80 percent of the energy wasted by being converted to other forms while 20 percent being converted to light energy. Adoption of Renewable Energy One of the ways adoption of renewable energy has contributed towards the conservation of natural resources is through enhancing energy security. When one looks at some of the renewable sources of energy such as solar, wind and geothermal, all these sources provide viable...

At this time, the concept of a national park was new for people; however, it was a great thing because it allowed the people the ability to preserve and protect the best of what they had for the benefit and enjoyment of all future generations. Yellowstone National Park is located in a rugged region where the states of Idaho, Wyoming, and Montana come together. This rugged region is made up of alpine and sub-alpine forests, as well as, mountains of high elevation. Recognized for its ecological value, Yellowstone national park was designated as a Biosphere Reserve in 1976; a biosphere reserve is an environmental area which is highly sensitive that has protected status, which is managed primarily to preserve natural ecological conditions. This paper on Yellowstone national park will be discussing the impacts associated with agriculture, the effects that a growing human population can have on the resources of an ecosystem, a management practice to help with sustainability, the risks and benefits for extracting renewable and nonrenewable energy resource for the ecosystem, and management practices for sustainability and conservation of natural resources and energy.

Once of the marine ecosystems that has been a central focus, especially recently, is the Gulf of Mexico. The Gulf of Mexico is located off of the Atlantic Ocean, and it is considered to have a tropical climate. According to epa.gov, The Gulf of Mexico is the ninth largest body of water in the world. Some of the species or habitants that dwell in the gulf are different types of whales, dolphins, sea turtles, and sea-birds. Along the sea floor there are coral reef situated. There are also large birds The Gulf of Mexico produces a variety of resources that we use. One of the main resources is the fisheries provided in the gulf. Fisheries in the gulf are considered one of the most productive in the world. In 2010, the estimated shellfish and commercial fish harvest from the gulf fisheries was estimated to be about 1.3 billion pounds (epa.gov). Agriculture is definitely affected by the Gulf of Mexico. There is currently an area that is called the dead zone. Within this area of the gulf, there is an excessive supply of nitrogen in this area due to fossil fuel combustion, crop cultivation, and synthetic nitrogen fertilizers. With the increase of nitrogen, there is a process that is called hypoxia that will occur. Many people believe that the species in the fisheries will be affected which will definitely...

Natural Resource Expansion

...on Bloomberg.com discusses the market of natural gas that Alaska’s North Slope has in reserves and the need of this valuable commodity in regards to the countries of Asia, especially China. The state government of Alaska and large natural resource and exploration companies including Exxon Mobile Corp, BP Plc., and ConocoPhillips are currently planning construction of the transportation pipeline and the facilities needed to compress the natural gas into liquid and ship it to their potential consumers. The article states that this venture would generate as much as $20 billion in annual LNG (Liquefied Natural Gas) sales. The 800-mile pipeline project from northern Alaska to a southern port may cost $20 billion to $26 billion; about three times as much as TransCanada Corp.’s Keystone pipeline proposal to link Canada’s oil to the U.S. Gulf Coast, according to a 2010 estimate of the Alaska project. Industry estimates have also pegged Alaska’s Liquefied Natural Gas total project cost at $40 to $50 billion, factoring in a pipeline and liquefaction plant. (Klump 2012 Paragraph 9-10) Alaska’s marketing of the reserves to the lower 48 states has been slowed by technological advances in the process of fracking to obtain natural gas within the continental US. Fracking is the process of drilling deep into shale strata and fracturing the material to release the natural resource. This process is driving future prices down and lowering the natural gas prices to levels never seen before. The...

Of Environmental and Natural Resource Economics

...enough to achieve over people, let alone trying to control the physical environment (Thomas 2007, p.7). Another fundamental issue for policy-makers is the direction of the policy. In particular they have to consider whether they are attempting to prevent environmental impacts that result from human action, or whether they are attempting to adapt to such changes, consciously or unconsciously (Thomas 2007, p.8). Natural Resources Natural resources have been critical for human welfare since people first started to walk the earth several million years ago (Field 2005 p.27). Natural resource economics is the study of how the flow of goods and services derived from natural resources is, and should be, managed in today’s world (Field 2005 p.37). Field continues to state that resource management problems derive from the underlying technological, institutional and cultural factors that characterise the economy (2005, p.37). Given the information concerning environmental policy and the importance of natural resources to human welfare and, the fact that our natural resources are under threat not just for today’s generation but for future generations.

Natural Resources and Energy Paper

...Natural Resources and Energy Paper A forest is a natural resource needed by the earth, humans, and species. There are three types of forests. The three types include “tropical, temperate, boreal forests” (The forest biome p. 1, 2006). Recently forests occupy about “one-third of Earth’s land area, and account for over two-thirds of the leaf area of land plants, and contain about 70% of carbon present in living things” (The forest biome p. 1, 2006). Forests produce vital oxygen and provide homes for people and wildlife. Forests play a critical role in mitigating climate change. A forest have several management practices for sustainability and conservation. There are several risks and benefits of extracting and using one type of nonrenewable and one type of renewable energy. The growth of human population has affected forest resources in several ways. The affected forests have caused harm to the population of wild species and have majorly impacted agriculture. Impacts associated with agriculture Between 2000 and 2010 about 13 million hectares of forests were lost per year to agriculture and other uses (Food and Agriculture Organization of the United Nations, 2013). Agroecosystems are very different from the ecosystems seen in nature. Unlike natural ecosystems, agroecosystems are large areas that have been planted with a single species or single strain or subspecies. This often makes them more susceptible to disease. Also, the agroecosystems are often planted in simple geometric...

Tropical rainforests “cover about 2% of earth’s surface, but house over half of world’s plant and animal species…” (Iowa Public Television, 1995-2010). Rainforests are vanishing quickly off the earth; over half have been destroyed in the last 10 years. While undefined, there are effects on the tropical rainforest based upon growing human population. There are proper management practices for conservation of natural resources but it is still necessary to determine the risks and benefits of extracting energy. Throughout this essay these points will all be discussed. Effects of Human Population Human population growth directly impacts the natural environment, natural resources, and ecosystems. The majority of tropical rainforests are located in moderately developed and developing nations that are experiencing exponential population growth. Wright maintains that 95% of the world’s population growth is occurring in developing nations at a rate of 1.5% annually, adding 75 million in a year (2008). Population growth adds pressures to natural resources as the need for living space, agricultural land and, food supplies increases. The biggest and most devastating...

Include the following: • Choose a specific ecosystem, such as a forest, grassland, or a marine or freshwater aquatic ecosystem. • Identify impacts associated with agriculture. • Identify and discuss the effects that a growing human population may have on that ecosystem’s resources, including loss or harm to populations of wild species. • Discuss one management practice for sustainability and conservation of natural resources in that ecosystem. • Identify the risks and benefits of extracting or using one type of nonrenewable and one type of renewable energy resource from that ecosystem, or in areas near that ecosystem. • Assess management practices for sustainability and conservation of natural resources and energy. Include two outside references. Format your paper consistent with APA guidelines. Forests conversion involves removing natural forests to meet other land needs, such as plantations, agriculture, pasture for cattle settlements, and mining. Unfortunately after the process of farming is complete the outcome is irreversible. The outcome is irreversible since deforesting land for farming; the soil is depleted of its nutrients. As the population grows more and more lands are being stripped to provide wood and land use for agriculture. One management practice is logging and which are located on steep slopes, the effects of these activities on watersheds will depend mainly...

...------------------------------------------------- Yellowstone Ecosystem Learning Team “C” 12/7/2015 Instructor: Dr. Ted Smith Yellowstone Ecosystem One of the largest and most complicated ecosystems on Earth is the Greater Yellowstone Ecosystem. This ecosystem is home to everything from mountains, lakes, forests, geysers, rivers, and meadows. Because this area is so large, it is the habitat to thousands of different species of plants and animals. In this paper we will discuss the natural resources and energy initiatives of the ecosystem and the functions in place to actively sustain them. ------------------------------------------------- There have been many impacts associated with agriculture at the Yellowstone National Forest. Agriculture is significant part of the forest lands but it has declined over the years yet, the park continues agricultural crop. The Yellowstone ecosystem has very high plant productivity. There have been houses built in certain areas where biodiversity is most essential, exclusively around grizzly bear territory, bird habitat, and anywhere along rivers and streams. Over the last few years, climate change has impacted Yellowstone National Forest and not necessarily in a positive way. It is predicted that 25 years from now, climate change will most likely strip away from forest ecosystems, specifically the one that supports Yellowstone National Park due to rising temperatures increasing so much and having the high chance of catastrophic...
