Wetlands - Why We Need Them essays

Wetlands - Why We Need Them essays "Wetlands", according to a description found at North Carolina State Universitys website, is the collective term for marshes, swamps, bogs, and similar areas. Wetlands are found in flat vegetated areas, in depressions on the landscape, and between water and dry land along the edges of streams, rivers, lakes, and coastlines.

Coastal and estuarine wetlands receive water from precipitation, surface water, tides, and/or ground water. Surface water sources include runoff and stormwater. Since the 1600s, more than half of the original wetlands in the lower 48 states have been destroyed. Wetlands have been drained and converted to farmland, filled for housing developments and industrial facilities, and used as receptacles for waste. Human activities continue to adversely affect wetland ecosystems. (NCSU) More recently, society has begun to understand the functions of wetlands and the values humans obtain from them. Wetlands help regulate water levels within watersheds; improve water quality; reduce flood and storm damages; provide a habitat for fish and wildlife; and support recreational activities, such as hunting, fishing and others. Wetlands are important features in watershed management. (NCSU) OFFICIAL DEFINITIONS AND CLASSIFICATIONS Although federal agencies, states, and text book authors vary in the way in which they define wetlands, in general terms, wetlands are lands on which water covers the soil or is present either at or near the surface of the soil or within the root zone, all year or for varying periods of time during the year, including during the growing season. The recurrent or prolonged presence of water (hydrology) at or near the soil surface is the dominant factor determining the nature of soil development and the types of plant and an...

Societal Implications of the USA Patriot Act and How It Limits Daily Essay

Societal Implications of the USA Patriot Act and How It Limits Daily Life - Essay Example It is evidently clear from the discussion that one of the main ways the patriotic act limited people’s daily lives is by making them accept the unreasonable casual violation of their basic rights. For instance, the act made Americans accept without question that security agencies can subject them to unreasonable searches and seizures when they are traveling. The patriotic act limits the rights of Americans by increasing the capabilities of government to carry out surveillance in four areas. The act gives the government the power to conduct record searches. It does this by expanding the ability of the government to examine records indicating a person’s activity that are in third-party possession. The Patriotic act also authorizes secret searches that enable the government to search private property without issuing a notice. The Patriotic act also authorizes the government to conduct intelligence searches by extending an exception to the fourth amendment that was made to enable the government to gather foreign intelligence. The act also allows the government to engage in trap and trace searches by enabling the government to track the source and targets of communications and the content. The provisions of the patriotic act limit daily life by violating individual privacy. The act gives the government unchecked power to examine a person’s internet usage, medical history, library usage, and any other activity that leaves a record of some kind. This not only violates individual right to privacy protected in the fourth amend but may make people refrain from certain activities for fear of being watched by the government.

Study skill Essay Example for Free

Study skill Essay Study skill is defined as the different abilities that can be developed in order to improve a learners capacity to learn (MONDOFACTO, 2009). Based from the free dictionary (n. d. ), the term study skill is used for general approaches to learning, rather than skills for specific courses of study. There are many theoretical works on the subject, and a vast number of popular books and websites. In the 1950s and 1960s, college instructors in Zthe fields of psychology and the study of education used research, theory, and experience with their own students in writing manuals. Marvin Cohn based the advice for parents in his 1979 book Helping Your Teen-Age Student on his experience as a researcher and head of a university reading clinic that tutored teenagers and young adults. According to the National Commission on Excellence in Education (1984), many students are unsuccessful in school because they lack effective study skills (MutsotsoAbenga, 2010). College students face various sources of academic stress, including demonstration of an ability to engage in challenging materials under time limitation (AfsanehHassanbeigi, JafarAskari, Mina Nakhjavani, ShimaShirkhoda, KazemBarzegar, Mohammad R. MozayyanHossienFallahzadeh, 2011) especially examination (Helen, 2013). To counter this, the commission recommends that study skills be introduced to students very early in the schooling process and continue throughout a student’s educational career (MutsotsoAbenga, 2010). In a now classic study of study skills, Entwistle (1960) reported that students who voluntarily took a study skills course were more successful academically than similar students who did not voluntarily take the course(MutsotsoAbenga, 2010). Haynes (1993) reported that improving study skills techniques can enhance academic achievement for students with poor study skills habits (MutsotsoAbenga, 2010). One such initiative was launched by the Louisiana State Board of Elementary and Secondary Education (BESE)(MutsotsoAbenga, 2010). This initiative, â€Å"The Dynamics of Effective Study,† was intended to help students succeed in high school by providing them with essential study skills(cited in Louisiana Department of Education, 1987)(MutsotsoAbenga, 2010). According to documents produced by BESE, the â€Å"Dynamics of Effective Study† course was designed to help students â€Å"learn how to learn† so that they can become effective, well-organized, and self-directed learners (cited in Louisiana Department of Education, 1987)(MutsotsoAbenga, 2010).
