Colonization Essay #1 Although New England and the Chesapeake regions were settled largely by people of English origin, by 1700 the regions had evolved into two distinct societies. I have described both societies in an attempt to demonstrate their developments. Virginia Colony In 1607 a group of merchants established England’s first permanent colony in North America at Jamestown, Virginia. They operated as a joint-stock company that allowed them to sell shares of stock in their company and use
BIODIVERSITY
BIODIVERSITY
BIODIVERSITY Biodiversity, as defined by E.O. Wilson, is meant to be all inclusive- it's the genetic based variation of living organisms at all levels, from the variety of genes in populations of single species, through species, on up to the array of natural ecosystems. This includes plants, animals, insects, fungi, bacteria, and all microorganisms. All of these things create what is known as a web. These things interact with each other in some way there for they depend on one another throug

Chinook Salmon Environmental Science Wednesday, February 26, 1997 Among the many kinds of fish harvested each year by commercial fisheries is the Oncorhynchus tshawytscha or Chinook salmon. The United States catches an averages of about three hundred million pounds of salmon each year. However some Chinook salmon have been recently listed as threatened. Man has been the main cause for the decline in Chinook salmon populations. The populations of Chinook salmon have declined for several reasons.
Effects of Deforestation
Effects of Deforestation
Effects of Deforestation The subject of deforestation and the effects that it has on the environment have been heavily debated for a long time; particularly over the last few years. Governments and large lumber companies see large profits in the mass deforestation of forests and state that their actions are having few, if any, harmful effects on the environment. Most people disagree with this and think that the environmental effects are devastating and will become irreversibly disastrous in the
Estuaries
Estuaries
Estuaries An estuary is a coastal area where fresh water from rivers and streams mixes with salt water from the ocean. Many bays, sounds, and lagoons along coasts are estuaries. Portions of rivers and streams connected to estuaries are also considered part of the estuary. The land area from which fresh water drains into the estuary is its watershed. Estuaries come in all shapes and sizes, each unique to their location and climate. Bays, sounds, marshes, swamps, inlets, and sloughs are all exampl

Endangered Species Study: Jaguars I. The jaguars of Central and South America have been being killed for game and protection. This cat used to have homes around the United States to Uruguay, but ever since the fears of extinction the jaguars have moved to the undeveloped rain forests in Latin America. Jaguars are being killed due to many people fearing for their own lives and many are also being killed to protect cattle. Jaguars do stalk and ambush their prey, however, they rarely ever attack ma
Manatees
Manatees
Manatees Quietly, but swiftly, the plump, dark animal glided across the water while making sounds comparable to that of the squeaks and squeals of a whale (Florida Manatee 1). Some would say these aquatic mammals are the ugliest thing below the surface, others would say that these animals are beautiful and resemble portly mermaids, but no matter what anybody says about the manatees, they are unique creatures (Ray and Ciampi 315). They are mammals that are completely harmless, they feed mostly

An Ecosystem's Disturbance by a Pollutant Paul Cordova L. Lehr December 11, 1995 Freedman defines a pollutant as the occurrence of toxic substances or energy in a larger quality then the ecological communities or particular species can tolerate without suffering measurable detriment (Freeman, 562). Although the effects of a pollutant on an organism vary depending on the dose and duration (how long administered). The impact can be one of sublethality to lethality, all dependent upon the factor

Water Biomes Marshland is covered with grasses, reeds, sedges, and cattails. These plants all have their roots in soil covered or saturated with water and its leaves held above water.Marshes may be freshwater or salt. Freshwater marshes develop along the shallow edges of lakes and slow-moving rivers, forming when ponds and lakes become filled with sediment. Salt marshes occur on coastal tidal flats. Inland salt marshes occupy the edges of lakes. They affect the supply of nutrients, the movement

Aspects of City Life - Crime. Different angles can be taken with regards to crime in the city, and further to this, the main topic can be broken down into smaller areas. I have conducted two types of research; Primary - Interviews etc. Secondary - Named Sources. The question of crime and how it affects a city is perhaps best put to those people that have either lived in a city all their lives (thus knowing what the crime is like in the area), or to those that have moved to a city from a town or

Bald Eagles and Golden Eagles
Bald Eagles and Golden Eagles Eagle is the common name for a number of diurnal birds of prey, some of which are the largest members of their family which also includes kites, hawks, buzzards, and certain vultures. The name eagle is somewhat loosely applied, as several of the groups are not particularly closely related to one another, and some birds called hawks are larger than some called eagles. The Bald Eagle (Haliaeetus Leucocephalus) and the Golden Eagle (Aquila Chrysaetos) are two eagles t

Shakespeare's Definition of a Ghost
Shakespeare's Definition of a Ghost
Shakespeare's Definition of a Ghost The American Heritage Dictionary, published in 1973, defines a ghost as, the spirit or shade of a dead person, supposed to haunt living persons or former habitats. Unfortunately, this simple definition does not explain where a ghost comes from or why it haunts. When used in the context of Shakespeare's Hamlet, this definition seems to suggest that the ghost who visits Hamlet truly is his dead father seeking revenge. To the modern reader, this straightforwar

Many people feel that animals have no rights and are here solely for our use. Humans are animals too, we shouldn't take advantage of other animals just because they can't reason like us. Animals are used in medical research labs as experiments. These experiments are meant only to benefit humans. I'm not totally against testing,some good can come of it. But when are tortured and abused in the process then there is something wrong with it. For example in the early 1980's baboons were involved in

In my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence of a supposed omnipotent being. Yet, th

DINOSAURS
DINOSAURS Dinosaur is the name of large extinct reptiles of the Mesozoic Era, during which they were the dominant land animals on Earth. The term was proposed as a formal zoologic name in 1842 by the British anatomist Sir Richard Owen, in reference to large fossil bones unearthed in southern England. The various kinds of dinosaurs are classified in two formal categories, the orders Saurischia and Ornithischia, within the subclass Archosauria. The first recorded dinosaur remains found consisted

The sea is the most obvious feature of the earth's surface. Approximately seventy percent of this surface is covered by water, in one way or another. Beneath this water are the familiar sands of the beaches, bottoms of bays, and the inshore ocean. Farther offshore this water covers an amazing submarine topography of underwater canyons, trenches, mountains, and plains. Unlike the continents, which are physically separated from one another, the oceans are continuous and interconnected. Since the

They are some of the most destructive and lethal viruses that human kind has ever seen. They seem to affect most of the body and it’s organs with some rather gruesome symptoms. Although most die ending their suffering, some survive to relay the story of their pain. The Marburg virus described in The Hot Zone , by Richard Preston, exemplifies these ne

As long as the human race has been cultivating the soil, we have had to deal with other vegetation that ends up competing with the crops. People have tried many methods to get rid of these pesky weeds but they always seem to come back. This eventually led to development of pesticides and herbicides. Herbicides allowed people to kill off the unwanted weeds. Over time these herbicides became more and more specialized allowing them to only harm certain weeds as needed such as broad leaf killers. O

Why should we save resources? Saving resources will help to decrease pressure on the natural environment, ensuring that habitats, landscapes and species are conserved. It will also delay the running out of these essential resources as well as reducing the need for transporting them. The data strongly support the hypothesis that countries with more unequal distribution of factor income redistribute more in favor of the poor - even when the analysis controls for older people's share in total popul

Some lakes are the source for some rivers. Important rivers, most often, originate from lakes. Some rivers end in lakes. Since both rivers and lakes are freshwater and flow in and out of each other, they share similar charcteristics and many species reside in both habitats. LOCATION: Freshwater ecosystems inclu

Climate Climate change is a growing concern as well, though it is somewhat debatable as to whether or not humans caused it. Natural changes in weather have had perhaps the greatest affect on biodiversity and ecological systems. The threat of humans shifting the climate is therefore extremely threatening to the natural environment. Were the average temperature to rise by several degrees Celsius, that warming would probably be followed by potentially large reorganizations of some ecological commun

This attitude towards cloning has been held into belief up until recently when scientists in Scotland cloned a sheep. And immediately after scientists in Oregon cloned a monkey (Fackelmann 276). The most major breakthroughs of the century in science has occurred and we are not ready for it. The scientific breakthrough of cloning has caused a great deal of controvers

The greenhouse effect is the absorption of energy radiated from the Earth's surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades. For th

Coral reefs are found mostly in warm, shallow, and tropical seas, because the reef-forming corals cannot live in water colder than 65 °F (18 °C). Reefs abound throughout the South Pacific, in the East Indies and the Indian Ocean to Sri Lanka, and around Madagascar on the southeastern African coast. They also form along the tropical eastern coast of Brazil, through the West Indies, along the Florida coast, and at Bermuda. There are three types of coral reefs: (1) fringing reefs; (2) barrier reef
Effects of Acid Rain on Water
Effects of Acid Rain on Water
Effects of Acid Rain on Water The effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and marshes. Acid rain flows to streams, lakes, and marshes after falling on forests, fields, buildings, and roads. Acid rain also falls directly on aquatic habitats. Most lakes and streams have a pH between 6 and 8. However, some lakes are naturally acidic even without the effects of acid rain. Lakes and streams become acidic (pH value goes down) when the
