Landfills It has long been believed that the largest entity brought upon the Earth by humankind is the Pyramid of the Sun, constructed in Mexico around the start of the Christian era. The mammoth structure commands nearly thirty million cubic feet of space. In contrast, however, is the Durham Road Landfill, outside San Francisco, which occupies over seventy million cubic feet of the biosphere. It is a sad monument, indeed, to the excesses of modern society [Gore 151]. One might assume such a mon
Lead Lead is a lustrous, silvery metal that tarnishes in the presence of air and becomes a dull bluish gray. Soft and flexible, it has a low melting point (327 C). Its chemical symbol, Pb, is from plumbum, the Latin word for waterworks, because of lead\'s extensive use in ancient water pipes. Itsatomic number is 82; its atomic weight is 207.19. Lead and lead compounds can be highly toxic when eaten or inhaled. Although lead is absorbed very slowly into the body, its rate of excretion is even slo
Malaria Malaria is regarded as one of the world\'s deadliest tropical parasitic diseases. It claims more lives than any other communicable disease except tuberculosis. In Africa and other developing countries, it also accounts for millions of dollars in medical costs. Malaria, however, is a curable disease if promptly diagnosed and adequately treated. Malaria is a mosquito-borne disease caused by the parasite plasmodium. In recent years, most cases in the U.S. have been in people who have acquir
Managing Planet Earth In William Clarks\' Article, Managing Planet Earth from the Scientific American sustainable development describes the type of planet people want, and also brings up the question of what kind of planet people can actually get. It reflects values for managing earth where fairness matters. Sustainable development refers to how people as a whole want to improve the earth for the better by sustaining it while it is being developed. The three objectives to manage the sustainable
Microwaves Microwaves You might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as Our Miracle Ally . But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such was the beginning of microwave cooking. The very same ene
Neuropsychologist A neuropsychologist is a psychologist who specializes in studying brain behavior relationships. Neuropsychologists have extensive training in the anatomy, physiology, and pathology of the nervous system. Some neuropsychologists specialize in research while other neuropsychologists specialize in evaluating and treating people who are thought to have something wrong with the way in which their nervous system is functioning. Neuropsychologists study brain behavior relationships un
Origin Of Species Considered one of the most significant, influential, and controversial publications in history, this book, I felt would be interesting to read and learn from. Although his content in this particular book is the subject of much controversy, Darwin\'s proffesional contributions and accomplishments will remain well known and respected. Therefore, I selected The Origin of Species believing that it would prove to be a stimulating and challenging reading experience. This famous book
Pesticides Pesticides are chemicals that are used to destroy pests. In the agricultural industry, pesticides are classified into two categories, carcinogenic and non-carcinogenic. A carcinogenic pesticide is a substance or agent producing or inciting cancer. Conversely, a non-carcinogenic pesticide is substance that does not produce or incite cancer. Most agricultural pesticides were registered in the 1950’s, with no standard regulations. The most considerable standard prior to the amendments of
Phytoremediation Introduction: In recent years it has become clear that some environmental chemicals can cause risks to the developing embryo and fetus. Evaluating the developmental toxicity of environmental chemicals is now a prominent public health concern. The suspected association between TCE and congenital cardiac malformations warrants special attention because TCE is a common drinking water contaminant that is detected in water supplies throughout the U.S. and the world. There is a lot of
Polar Bears Polar bears are big, white bears (sometimes darker fur) that live in very cold regions like around the artic poles. There are 21,000 to 28,000 Polar bears alive that are known. Polar bears swim in water and are carnivores, they eat fish . Polar bears feed mainly on ringed seals and bearded seals. Depending upon their location, they also eat harp and hooded seals and eat carcasses of beluga whales, walruses, narwhals, and Bowhead whales. A polar bears\' stomach can hold up to 15% to 2
Rainforest Dilema Can you picture our earth without forests? Many of us can’t. Forests cover approximately one fifth of the worlds land surface and play an important role in our everyday lives (Dudley 4). Forests provide us with many products and services from helping maintain erosion to providing jobs for our citizens. Humanity depends on the survival of a healthy ecosystem and deforestation is causing many social, economic and ecological problems. One ecological problem is Global warming witch
Reproduction For some time she had watched his movements, appearing coyly in his haunts. And now, had it paid off? Doubtless, he was in love. His muscles were taut; he swooped through the air more like an eagle than a Greylag gander. The only problem was, it was not for her that he then landed in a flurry of quacks and wingbeats, or for her that he dashed off surprise attacks on his fellows. It was, rather, for another - for her preening rival across the Bavarian lake. Poor goose. Will she mate
Science; Rainforests And Earth The Tropical Rainforests of the World In this term paper, I will explain the great importance of the tropical Rainforests around the world and discuss the effects of the tragedy of rainforest destruction and the effect that it is having on the earth. I will talk about the efforts being made to help curb the rate of rainforest destruction and the peoples of the rainforest, and I will explore a new topic in the fight to save the rainforest, habitat fragmentation.

Snow Goose Overpopulation The Overpopulation of the Snow Goose in North America Abstract The purpose of this paper is to explore available research on the overpopulation of the Snow Goose on the North American continent. The snow goose has been rising in population since the middle of the century and has been escalating so much it is destroying their natural habitat. Wildlife managers have just recently begun to implement strategies to combat this problem. Mainly through the use of hunters the m
The Immune System The immune system is a group of cells and organs that defend the body against invaders causing disease. The immune system is made up of mostly white blood cells and their contact with lymph nodes, spleen, tonsils, intestines, and lungs. The immune system rejects and attacks any substances not normally present within the human’s body. Innate, or nonspecific, immunity, is functioned by the skin, tears, mucus, and saliva. These barriers protect the body from a disease’s entrance,
The Importance of Mining Industry The importance of mining is definitely significant to Canada. Mining, is an important industry, and Canadians are very advanced in their mining technology, but during the mining process, there is certain level of pollution produced. The Canadian government and the mining companies have very good plans and controls toward this problem, while ensuring the smooth running of the industries, and also helping to create strong economy and employment. The world of today
The Origin Of Humanity We live on a planet believed to be 4.5 billion years of age with millions of people covering all parts of it. Where did they come from? Did the whole human population originate from one of people or were we placed here and then improved or changed by an intervention? I believe that humanity on planet earth was created by evolution. Both the creationist and interventionist theories seem to far fetched to be accountable theories for the creation of humanity on planet earth.
Transgenic Rice Plants For centuries, rice has been one of the most important staple crops for the world and it now currently feeds more than two billion people, mostly living in developing countries. Rice is the major food source of Japan and China and it enjoys a long history of use in both cultures. In 1994, worldwide rice production peaked at 530 million metric tons. Yet, more than 200 million tons of rice are lost each year to biotic stresses such as disease and insect infestation. This ext
Tumours A tumour is a mass of new tissue growth that does not react to normal controls or the organizing influence of other tissues, and it has no useful function in the body. This applies to both types of tumours, malignant and benign. Malignant, also known as, cancerous tumours, are additionally defined by their invasion of local tissue and their ability to spread to other parts of the body. Benign Tumours A benign tumour which is not cancerous, is less serious than malignant tumours because t

Scientology Scientology is a fairly new religion. Founded in the twentieth-century by a man by the name of L. Ron Hubbard. He began his studies long ago and wrote a book in 1950 called Dianetics: The Modern Science of Mental Health. He claimed that this book was one of the first tools used to solve the problems of the mind. This book focused on irrational mind, war, crime, and insanity. Mr. Hubbard designed this book so that anyone can use it to improve oneself. He did not stop at Dianetics, how
A Review Of Psychology Articles In this paper I will review four articles, one movie, and one experiment conducted in class. The issue\'s all this information covers is sex differences and the degree to which they exists in men and women and why they are present. There will be varying points of view for all these issues with each article having its own studies or theory \'s to support its beliefs. The method for presenting this information will first be summaries of the media gathered then a gen
Adolescence and Delinquency I couldn\'t begin to cover all the possible reasons that may cause an adolescent to become a juvenile delinquent. During my research, I found that the term juvenile delinquency is defined a number of ways. Mosby\'s Medical Nursing, and Allied Health Dictionary summed up juvenile delinquency best with this definition; resistant antisocial, illegal, or criminal behavior by children or adolescents to the degree that it cannot be controlled or corrected by the parents, en
Nature vs Nature Nature vs. Nurture Psychologists have often questioned whether personality traits are inherited, and therefore a result of genetics, or if they are caused by the environment, and are therefore made. This has come to be known as the nature versus nurture controversy. Many psychologists throughout history have asked this question, and most agree the answer is both. Nature versus nurture has been an on going argument for over a century and will carry on further. Scientists have bee
Biological Determinism 1. According to the author of the article "All in the Genes?", there is no intrinsic causality between genetics and intelligence. The author analyses different aspects of biological determinism, and supplies many examples, which illustrate aspects of this problem that are being discussed since the time when these ideas became popular. He does not agree with biological determinist that the intellectual performance of a person depends on genes inherited from his parents. The
Lamarck\'s Influence on the Development of Darwin\'s Theory of Evolution Dec. 4 1996 Marc Weinstein There have been many ideas on the theory of evolution. Some simply take our existence for granted, others prefer to explain all evolution in terms of the bible and the presence of a God. However, there are those who have researched the topic of evolution and have offered an explanation as to where a species comes from and how they evolved in the manner that they did. This type of science has been
Nurture Plus Nature Raegan Robb Psych101 Dec.9th 1996 The classic debated topic of nurture versus nature has been, and always will be an argumentative subject in the scientific world. Some psychologists and scientists share the view that our behavioral aspects originate only from the environmental factors of our upbringing. While other opposing specialists argue the outlook in science that agrees with the naturalist idea. This concept of naturalistic ideas supports the hereditary genetic framewo

Legalization of Drugs Man, as a creature, is inherently bored. Since the dawn of time, it has been the natural instinct of man to find alternative methods to enhance his being.

The consumption of substances can be further broken down into legal and illegal substances. The question then becomes, who are we to place labels on certain substances by deeming them le
Decriminalize Marijuana for the Good of America Currently, drugs remain high on the lists of concerns of Americans and are considered one of the major problems facing our country today. We see stories on the news about people being killed on the street every day over drugs. To many people drugs are only an inner-city problem, but in reality they affect all of us - users and non-users. I believe that the negative affects we associate with drugs would be greatly reduced if the United States adopte
Forestry Management Forestry Management in Nova Scotia The Canadian forest sector has been a strong and vital element of national and regional well being. Through the management, harvesting, processing and marketing of timber resources, Canada has developed a reputation of being one of the largest timber resources in the forest industry. However, to maintain this reputation and economic well being there are several issues to address in order to protect and sustain this renewable resource. This p

Animal Ethics Animal ethics is concerned with the status of animals, whereas environmental ethics concerns itself with the relationship to the environment. I will show the existence of animal ethics depends on the existence of environmental ethics. I will prove this by showing that such philosophers who have practiced animal ethics such as Singer, Regan, and Taylor are limited because they are individualistic. Which means they are limited to animal concerns, and nothing else. But with the enviro
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.

Global Warming Mission Plan a. Analysis of the Problem 1. History of the Problem Some scientist\'s have been concerned since 1896 about what might happen if there were 5.5 billion tons carbon dioxide in our atmosphere. In 1961 a British scientist did an experiment showing that the carbon in the air was absorbing some of the sun\'s radiation. Afterward a Swedish scientist, Suante Arrhenius, found out if the radiation of the sun was trapped in the carbon dioxide the temperature of the earth would
Global Warming The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earth\'s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the “greenhouse effect.”). The gases--water vapor (H2O), carbon dioxide (CO2), and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average woul
Changes in the Earth\'s Environment The 20th century, especially in the second half, has been one of rapid change in the Earth\'s environment. The impact of humans on the physical form and functioning of the Earth have reached levels that are global in character, and have done so at an increasingly mounting speed. 20 years ago the environment was seen as posing a threat to the future of humanity as death rates from natural hazards had increased dramatically since the turn of the century.

Ural Mountains David Bennington Bennington 1 Mr. Macintosh Environmental Science CP9 HR. 5 1/6/96 The Ural Mountains are a rugged spine across Russia, running 1,300 miles from the fringe of the Arctic in the North, to the bend of the Ural River in the South. Traditionally they form a boundary between Europe and Asia. The north- south course of the Urals is relatively narrow, varying from about 20 to 90 miles in width, but it cuts across the vast latitude landscape regions of the Eurasian landmas
Landfills: A Growing Menace When asked to think of the largest man made structure, people will invariably come up with an answer like The Great Wall of China, the Great Pyramids, or the Taj Majal. In contrast to these striking achievements of mankind is the Durham Road Landfill outside San Francisco, which occupies over seventy million cubic feet. It is a sad monument to the excesses of modern society [Gore 151]. One must think this huge reservoir of garbage must be the largest thing ever produc

Australians Against Further Immigration OUR VIEW Environment Humanitarianism Economics Health Defences Education Culture Australia\'s immigration policy is disastrous, proceeding as if there is no balance of payment problem, no foreign debt and no geographical or environmental constraints to population growth. Continued immigration will finally and irreversibly alter the natural and urban environment, economic viability and attitudes and culture of our nation. The people have been consulted on,
Accountability of Our Government Accountability is the essence of our democratic form of government. It is the liability assumed by all those who exercise authority to account for the manner in which they have fulfilled responsibilities entrusted to them, a liability ultimately to the Canadian people owed by Parliament, by the government and thus, every government department and agency. One of the fundamental principals of a democratic society is the government must be accountable to the people.
"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 facto

In Population Bomb, Ehrlich explains that pollution, shortages, and an overall deterioation of the standard of living is all due t
Human Cloning Isn\'t as Scary as It Sounds The recent news of the successful cloning of an adult sheep— in which the sheep\'s DNA was inserted into an unfertilized sheep egg to produce a lamb with identical DNA—has generated an outpouring of ethical concerns. These concerns are not about Dolly, the now famous sheep, nor even about the considerable impact cloning may have on the animal breeding industry, but rather about the possibility of cloning humans. For the most part, however, the ethical c
Nuclear Weapons In its attempts to harness the power of the atom, mankind has itself in the possession of weapons with unbelievable, destructive power. Nations now have the ability to destroy entire cities from hundreds of miles away, in only minutes. These weapons are nuclear weapons. Nuclear weapons cost the citizens of the United States billions of dollars in taxes each year, the testing and maintenance of these weapons pose serious health risks, and the actual need for these weapons is not a
