Hydric Soils as a Part of Water Treatment in Wetland Systems
Most basically, a hydric soil is defined as "A soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (Kent, 1994, p. 26)." Included by this definition in the United States Department of Agriculture/Soil Conservation Service's list Hydric Soils of the United States are all of the poorly drained and very poorly drained soils and most of the somewhat poorly drained soil series.
Hydric soils are further categorized into two major groups: mineral soils and organic soils. Histosols (organic soils) typically contain at least 46 cm of organic matter in the upper part of the soil profile. They are grouped by the degree to which plant material and fibers are decomposed. Most decayed are the saprists (muck), followed by hemists (mucky-peats and peaty mucks), and fibrists (peats), the least decomposed. (Folists, the fourth group of organic soils, are not regarded as hydric soils because the organic part is not inundation or saturation derived.)
Mineral soils ordinarily have less organic matter in the upper part of the soil profile than histosols. To be considered hydric soil, a mineral soil must meet specific drainage and water table criteria that indicate at least 15 consecutive days of saturation or 7 days of inundation during the growing season. Hydric mineral soils include soils in the Aquic subgroups, Aquic suborders, Albolls suborder, Salorthids great groups and Pell great groups of vertisols (Kent, 1994).
In the field, hydric soils are distinguished by indicators displayed within the root zone. These include histosols, histic epipedons, high organic matter content in the surface hori...

The first mitigation banking guidance was released in 1995 by the EPA and Corps of Engineers. The most recent wetland mitigation banking guidance was released in 2008. The idea behind both wetland mitigation banking and conservation banking is to provide compensation for unavoidable impacts to resources prior to the environmental impact taking place (FWS, 2003). Based on the rules set forth in section 10 of the Rivers and Harbors Act and section 404 of the Clean Water Act, wetland impacts are reduced by using the following sequence of steps: avoiding impacts, minimizing impacts, and as a last resort, mitigating for impacts. Although the Corps has enforced a mitigation policy to reg...
The Holocaust was a very impressionable period of time. It not only got media attention during that time, but movies, books, websites, and other forms of media still remember the Holocaust. In Richard Brietman’s article, “Lasting Effects of the Holocaust,” he reviews two books and one movie that were created to reflect the Holocaust (BREITMAN 11). He notes that the two books are very realistic and give historical facts and references to display the evils that were happening in concentration camps during the Holocaust. This shows that the atrocities that were committed during the Holocaust have not been forgotten. Through historical writings and records, the harshness and evil that created the Holocaust will live through centuries, so that it may not be repeated again (BREITMAN 14).
Stem cell research is a heavily debated topic that can stir trouble in even the tightest of Thanksgiving tables. The use cells found in the cells of embryos to replicate dead or dying cells is a truly baffling thought. To many, stem cell research has the potential to be Holy Grail of modern medicine. To many others, it is ultimately an unethical concept regardless of its capabilities. Due to how divided people are on the topic of stem cell research, its legality and acceptance are different everywhere. According to Utilitarianism, stem cell research should be permitted due to the amount of people it can save, however according to the Divine Command of Christianity, the means of collecting said stem cells are immoral and forbidden.

This essay will answer this question through a variety of means. In order to measure the question posed, we must first define the concepts of democracy, international peace and security. After having defined these, we must apply the promotion of democracy, using examples from the past to consider whether this is a worthwhile endeavour, and if so, how should we approach it to ensure we achieve what we set out to. This essay will give reference to, but will not provide a comprehensive analysis of, the ‘Democratic Peace Theory’.
The theory of democratic peace is a classical idea that has been cited repeatedly by scholars. While Kant was not a darling of democracy, he wrote about perpetual peace, which he describes would only happen if states achieve a form of civil constitution. To him, perpetual peace exists when a regime honors property owned by citizens and when citizens live equally being the subjects based on a representative government that is built on the premise of separation of powers. The theory of democratic peace is therefore built on the proposition that some negative elements of government can be disabled to make a nation thrive in an international arena. This majorly entails elements of war. This idea is strengthened by the fact that relations between states in an international setting are not provoked by benefits of one nation being a burden to another. Instead, these relations are based on a mutual benefit and togetherness. If that proposition is anything to go by, it loses it meaning when states behave contrary to what they suggest on an international platform. The internal structures of a state are paramount to such an atmosphere and when they lead a different style of relationship with other states, the theory of perpetual peace fails to hold any water. The behavior of states can only be explained...
...n, the Louisiana wetlands are an extremely valuable asset to the State of Louisiana and the United States. The continual loss of Louisiana wetlands has the potential to have an immensely negative effect on the economy at a state and national level. Over 2 million people live in the Louisiana coastal parishes (Field et al., 1991). The majority of people living on the Louisiana coast make their living from things that are directly related to the wetlands. The Louisiana wetlands make up the largest wetland community in America and is being lost at a rate greater than the other wetland communities in the country. The suggested strategies that are being taken into consideration could be helpful but it seems that the State of Louisiana is not as concerned as it should be given the future consequences and much like climate change coastal erosion is not being taken serious.
This paper introduces the environmental concerns of the loss of coastal wetlands. The paper will discuss the significance of wetlands and the devastation that is occurring because of human activity. Wetlands are an essential element of our environment both ecological and societal; conservation will be essential for the preservation of these precious ecosystems.

Between 300 and 400 million people worldwide live in areas near wetlands and depend on them. Wetlands are mechanisms for treatment of wastewater are extremely efficient because they absorb chemicals and filter pollutants and sediments. Half the world's wetlands have disappeared due to urbanization and industrial development. The only way to achieve sustainable development and poverty reduction will be through better management of rivers and wetlands, and the land they drain and drain as well as through increased investment in them.
Although the Manchus in China and the Tokugawa in Japan during the 17th and 18th centuries consolidated power into a central authority differently, their reasons for doing so were relatively similar, both being due to a certain internal conflict and their location relative to other empires.

The democratic peace theory stems from the generally optimistic liberal tradition which advocates that something can be done rectify the effects of an anarchical system, especially when it comes to war or conflict. For democratic peace theorists, the international system should be one in which there is cooperation and mutual benefits of the states are taken into consideration. The theory depends on liberal ideologies of civil liberties, democratic institutions and fairly elected governments and claims that liberal democracies are different from other systems of government as they do not conflict with other democracies due to the very nature of the liberal thinking and the pacifying role that democracy itself plays. According to the theory, the thought process behind democracies abstaining from war is that...
