Analysis Of The Metal Contaminant Pollution On Terrestrial Trophic Systems

Acidity of an ecosystem, measured in pH, is a crucial factor to the survival of a species in an ecosystem. Altering it can have result in dramatically negative effects, in spite of the fact that pH of an ecosystem has been dramatically changed over a relatively short period of time due to various human activities. For example, acid rain is a major environmental problem that is caused by human-made pollution. When fossil fuels are burnt to get energy, pollutants like sulfur dioxide and nitrogen oxides get mixed into the rainwater and eventually are evaporated into the atmosphere. These gases enter the atmosphere, and mix with water in the water cycle to form an acidic mixture of water and gases. This water falls in the form of acid rain, which

The use of too much fertilizers, and in particular, of fertilizers with high concentrations of nitrogen, has been linked to reduced biodiversity (Xiankai et al. 2010). It becomes necessary to consider the detrimental effects of high concentrations of fertilizer in the reduced spaces. Fertilizers are salts, and therefore high concentrations of fertilizers can deplete the plant from water.

Biomes are appropriate conditions for organizing the natural world because the organisms that live in them common constellations of adaptations, particularly the climate of each of the areas and the characteristic vegetation types that develops in these divisions. It should be understood that the climate is perhaps the most important in determining classes of individuals who may live in an area and the ways they should be amended to live under different conditions of temperature and precipitation and seasonal distribution of these factors element. Every place on Earth has its own climate, influenced by both macroclimate regions as the particular microclimate. The soils are very important because they are essential to determine the types of plants that will grow into a bioclimatic zone in partical, in addition, also as substrates for animals serve. In turn, the soils are heavily influenced by regional climate, as well as the geology of the bedrock. At the same time we have to keep in mind the diversity of plants like the flora just like the diversity of the fauna as well as the adaptation of both.

Vegetation is a key factor in determining the structure of an ecosystem. It determines many ecological parameters within a plant community such as microclimate, energy budged, photosynthesis, water regimes, surface runoff and soil temperature (Tappeiner and Cernusca, 1996). Vegetation of an area varies from place to place according to habitat heterogeneity of the area itself. The description and classification of the plant community in an ecosystem is known as Phytosociology (Braun-Blanquet, 1932; Odum, 1971). It’s an important characteristic in describing vegetation that offers a preliminary picture of the ecological character of the vegetation (Kershaw, 1973). Each site of study

The importance of this property cannot be overemphasized for its role on the ecosystem of Earth.

Deforestation’s accompaniment is erosion. Since much of strip mined land lacks proper restoration, weather causes further loss of soil and vital nutrients needed for native vegetation to grow. “Mountain Top Mining and Valley Fills Report” published by the EPA cites KA Harper and others educated and conducting studies in the fields of biology, environmental studies, and renewable sources. According to Harper, the change in mineral content of land affected by surface mining prohibits growth of indigenous plant life and allows foreign plant life to invade, changing the areas ecosystem (Harper).

The tomb is most famous for its large rows of soldiers, but there were plenty of other statues to accompany Emperor Qin in the afterlife. There were 150 life-size cavalry horses and 130 chariots with 520 horses buried with the army. In other areas of the tomb, figures of government officials and entertainers have been found.

Biogeochemical cycles are important to the sustainability of all life. Chemical elements necessary for the growth and reproduction of all organisms have a limited quantity on earth at any one time, other than the occasional meteor that brings with it new matter. It is therefore important that the recycling of these chemical elements is efficient. Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms that can inhabit these ecosystems. To understand the rates in which certain species’ leaves decay and release the energy stored within them can demonstrate how quickly the energy becomes available to organisms in higher trophic levels.

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be

Modern farming and agricultural operations contribute to the degradation and contamination of our environment as well as the neighboring ecosystems. Fertilizers, pesticides, herbicides, animal manure and other Argo-chemicals are rich in chemical nutrients and toxic substances which are often the major sources of agricultural pollution. The use of these various types of products can affect water quality when it rains, and the contaminated soils and water is washed into the waters or into ground waters. These chemicals can also be absorbed by plants which are then consumed by animals and even humans, harmful to animal and human health. There are many causes of this pollution.

The patterns of biological diversity in rivers and streams among taxa vary on a spatial and temporal scale (Ligeiro et al. 2010; McGarvey and Terra 2015). Variations in stream ecology can be contributed to water quality, habitat, and history of disturbance (Lingeiro et al. 2010). Creeks and streams feed into rivers and other larger bodies of water, which provide food, water, and other commercial and recreational services as well as a home to an array of plants and animals which rely on clean water. The health of these smaller bodies of water can act as indicators for the health of the larger watershed.

One of the most significant concerns that have existed in the ecosystem for decades now is the issue of pollution. Pollution in itself is the destruction of the normal concentration and manifestation of factors such as water, soil, air and others in the ecosystem. This destruction largely arises from the human activities that often lead to misbalance, increased wastes concentration and improper positioning of the necessary and unnecessary additions to the environment. This often leads to the destruction of biodiversity, which is an important balance to the whole cycle of living organisms in that they support each other for their co-existence. If at all the number of animals reduce in the world to a very small number then a threat is posed to the living organisms since it will translate to it having to reduce also (Turner 2014).

The Crucible, a play written by Arthur Miller, centers around the Salem witch trials where many people in Salem, Massachusetts are put on trial after being wrongly accused of working with the Devil. Whether or not they are accused, everyone in the play must confront their own crucible, a severe trial that will reveal their true character. They must decide whether to be a bystander and do nothing to help the innocent, or to fight for justice against the court’s wrongdoings. Revered Hale first comes to Salem as an expert in witchcraft determined to find the truth. He is confident in his abilities and is prepared to undercover the truth. When people are first accused, Hale knows in his heart that they are innocent, yet does nothing to help because he is worried about his reputation. Throughout the play, Hale experiences a change in his character when he learns that doing the right thing is more important than people’s opinions of him. Hale’s character development throughout the play mirrors the central theme of The Crucible as he goes through a personal crucible. This severe trial will ultimately reveal his integrity and moral courage as a guilty conscience and meticulous self examination lead Hale to attempt redemption.

committing a crime. As a society, we have the upmost interest in preventing murder, so we use the strongest punishment available to deter this crime, and that is the death penalty. The U.S. ranked fifth in the world in capital punishment, alongside China, Saudi Arabia, Iran, Iraq (Merino, 2015). Our society seeks to be good, defined as moral, upright, wholesome, and virtuous. None of these terms are associated with capital punishment, and we should abolish capital punishment for several reason. (U.S. News & World Report Weekly).
