Racial and Ethnic Diversity and Inequality essays

Racial and Ethnic Diversity and Inequality essays Racial and Ethnic Diversity and Inequality Prejudice is an unfavorable opinion or feeling formed beforehand or without knowledge, thought or reason. Prejudice may arise from many sources, including the views of family or peers, or it may come from strong identification with a particular group. From any source, prejudice is a problem that faces the American society today. As I enter the second semester of my college career I am able to better visualize the problem of racial and ethnic discrimination as well as prejudice. Living in such a diverse atmosphere as a college dormitory, helps make this topic more personal and easier for me to grasp. I live in an environment where people from different social categories have come together. Living with and around people of all races and ethnic backgrounds illustrates that people hold rigid opinions of members of a different social category. Prejudice is personally relevant to me because I am surrounded by people who often make social prejudgments about others before they even get to know them. I am examining the extent of prejudice through a survey of eleven questions designed to enable me to come to a general consensus about prejudice in todays society. By surveying twelve people of different gender, age range, and race, I wanted to find out societys universal perspective of prejudice, and its effects on society. Prejudice is a deep-rooted problem that does not just lie on the surface of society. Prejudice rests on stereotypes: overgeneralizations about a group and its members that go beyond existing evidence (Feagin and Feagin, 1996). Stereotyping is primarily used to call attention to beliefs that present an out-group in an uncomplimentary way and is usually a false generalization. Prejudice is principally harmful to ones emotions and or attitudes and more importantly can lead to discrimination. Discrimination is the denial of opportunities an...

Explore Fascinating Facts About Forest Biomes

Explore Fascinating Facts About Forest Biomes The forest biome includes terrestrial habitats that are dominated by trees and other woody plants. Today, forests cover about one-third of the worlds land surface and are found in many different terrestrial regions around the globe. There are three general types of forests- temperate forests, tropical forests, and boreal forests. Each of these forest types differs in climate, species composition, and community structure. The forests of the world have changed in composition over the course of evolution. The first forests evolved during the Silurian Period, about 400 million years ago. These ancient forests were very different than present-day forests and were dominated not by the species of trees we see today but instead by giant ferns, horsetails, and club mosses. As the evolution of land plants progressed, the species composition of forests changed. During the Triassic Period, gymnosperms (such as conifers, cycads, ginkgoes, and gnetales) dominated forests. By the Cretaceous Period, angiosperms (such as hardwood trees) had evolved. Although the flora, fauna, and structure of forests vary greatly, they often can be broken down into several structural layers. These include the forest floor, herb layer, shrub layer, understory, canopy, and emergents. The forest floor is the ground layer that is often covered with decaying plant material. The herb layer consists of herbaceous plants such as grasses, ferns, and wildflowers. The shrub layer is characterized by the presence of woody vegetation such as bushes and brambles. The understory consists of immature and small trees that are shorter than the main canopy layer. The canopy consists of the crowns of mature trees. The emergent layer includes the crowns of the tallest trees, which grow above the rest of the canopy. Key Characteristics The following are the key characteristics of the forest biome: largest and most complex terrestrial biomedominated by trees and other woody vegetationsignificant role in the global intake of carbon dioxide and production of oxygenthreatened by deforestation for logging, agriculture, and human habitation Classification The forest biome is classified within the following habitat hierarchy: Biomes of the World Forest Biome The Forest Biome Is Divided Into the Following Habitats Temperate Forests Temperate forests are forests that grow in temperate regions such as those found in eastern North America, western and central Europe, and northeastern Asia. Temperate forests have a moderate climate and a growing season that lasts between 140 and 200 days of the year. Precipitation is generally distributed evenly throughout the year. Tropical Forests Tropical forests are forests that grow in tropical and subtropical regions. These include tropical moist forests (such as those found in the Amazon Basin and the Congo Basin) and tropical dry forests (such as those found in southern Mexico, the lowlands of Bolivia, and the western regions of Madagascar). Boreal Forests Boreal forests are a band of coniferous forests that encircle the globe in the high northern latitudes between about 50Â °N and 70Â °N. Boreal forests form a circumpolar ecoregion that stretches across Canada and extends across northern Europe and Asia. Boreal forests are the worlds largest terrestrial biome and account for more than one-quarter of all the forested land on Earth. Animals of the Forest Biome Some of the animals that inhabit the forest biome include: Pine Marten (Martes martes) - The pine marten is a medium-sized mustelid that inhabits the temperate forests of Europe. Pine martens have sharp claws are good climbers. They feed on small mammals, birds, carrion, as well as some plant materials such as berries and nuts. Pine martens are most active at dusk and during the night.Gray Wolf (Canis lupus) - The gray wolf is a large canid whose range includes the temperate and boreal forests of North America, Europe, Asia and North Africa. Gray wolves are territorial carnivores that form packs of a mated pair and their offspring.Caribou (Rangifer tarandus) - The caribou is a member of the deer family that inhabits the boreal forests and tundra of North America, Siberia, and Europe. Caribou are grazing herbivores that feed on the leaves of willows and birches, as well as mushrooms, grasses, sedges, and lichen.Brown Bear (Ursus arctos) - Brown bears live in a variety of habitats including boreal forests, alpine forests and meadows, tundra, a nd coastal regions. Their range is the most extensive of all bears and includes northern and central Europe, Asia, Alaska, Canada, and the western United States. Eastern Gorilla (Gorilla beringei) - The eastern gorilla is a species of gorilla that inhabits the lowland tropical forests of the eastern Democratic Republic of Congo in central Africa. Like all gorillas, the eastern lowland gorilla feeds on fruit and other plant materials.Black-tailed deer (Odocoileus hemionus) - The black-tailed deer inhabits the temperate rainforests that blanket the coastal areas of the Pacific Northwest. Black-tailed deer prefer the edges of forests where understory growth is sufficient to provide them reliable food resources.
