Nuclear Weapons A major problem concerning the world today is the disposal of nuclear weapons. With the Cold War, we have seen a massive build up of nuclear weapons, and no, that we are no longer in a state of global warfare, what is to be done with them? As a result of the build-up in nuclear weapons during the cold war the world is now facing major environmental problems trying to deactivate them, and in addition major debate are occurring on the policies of disarmament and deterrence as solut

The Enviromnetal Degradation as a Result of Overpopulation 1 Introduction There are simply too many people on our planet, and the population is not showing any signs of slowing down(see Figure 1). It is having disastrous effects on our environment. There are too many implications and interrelationships to discuss in this paper, but the three substances that our earth consists of: land, water and air, are being destroyed. Our forests are being cut down at an alarming rate, bearing enormous impact
Acid Rain Legislation
Acid Rain Legislation
Acid Rain Legislation Acid rain is a destructive force as a result of nature and man colliding. It is formed through harmful industrial emissions combining with contents of the earth's atmosphere; a dangerous combination. This prompted governments throughout North America to take action. Many laws and regulations have been implemented, yet the question still remains, Should tougher legislation be implemented to force industries to reduce acid rain emissions? To decide whether tougher legislati

Acid Rain
Acid Rain As the century past, the industrial society kept advancing. However, many advantages of the industrial society brings us also has a down side. One of the adverse effects of industrialization is acid deposition due to power plant, fossil fuel and automobile emissions. Acid rain is the popular term but the scientists prefer the term acid deposition. Acid rain can have adverse effects on the environment by damaging forests or by lowering the pH of the lakes and making the water too acidic
Animal Ethics
Animal Ethics
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

David Suzuki's A Planet for the Taking In the essay A Planet for the Taking, David Suzuki describes Canadians' odd appreciation for this great natural bounty we call our own. He is an internationally acclaimed scientist who is concerned about the welfare of Canada. Suzuki's intended audience is the Canadian population that does not realize the grave danger they are instilling upon themselves by haphazardly taking our resources without looking at the subsequent repercussions of their actions.

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

Deforestation of the Pacific Northwest
Deforestation of the Pacific Northwest One of the most controversial areas associated with the global problem of deforestation is the Pacific Northwest of the US. The problem can be broken down into several issues that all tie in together. These include the near extinction of the Northern Spotted Owl, the business aspect of logging versus the environmental aspect, and the role of the government in this problem. In 1973, the Endangered Species Act (ESA) was passed. This enabled the Dept. of Com

Energy Flow Systems Richard White's Organic Machine, and William Cronon's Changes in the Land, both examine environments as energy flow systems. The energy flow model was utilized by the authors to explain relationships within ecosystems. Richard White's thesis is to examine the river as an organic machine, as an energy system that, although modified by human intervention, maintains it's natural, its “unmade” qualities. White emphasizes on energy because it is a useful concept that can be easily
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
Global Warming
Global Warming
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 would

Our Radiant Planet- Depletion of the Ozone Layer
Our Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that w

This blanket silences the expected sounds of the wetland environment, birds chirping, ducks splashing, insects buzzing and animals thriving. This unnatural silence is disturbing, the favourite flowers that used to litter this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy pur

The Influence of Green Groups on the Policy of the United States Abstract: This research examines the relationship between environmental groups and the policies of the United States. The United States political system has been historically anthropocen-tric, or human centered. Environmental groups have been attempting to change this to a biocentric or ecocentric viewpoint, which includes the rights of animals and the environment. These views are nature centered instead of human centered. This stu

I am your usual plant cell. There are trillions of my kind on all plants, grass, and trees. My breed ranges from ten to a hundred micrometers. I am approximately twenty micrometers since I dwell in grass. My organelles stretch out to one to ten micrometers. If you are asking what I really do and how I live, I am going to answer them in this paper. First off, any cells requires a structure, metabolism, energy, nutrients, waste, and communication. I am more complex than most other cells. Bacteria

Water Transitions
Water Transitions Brackish water is a fairly salty mixture of freshwater and sea water. It is unique in numerous ways and is a life giving ecosystem. To understand what brackish water is, a background should be known about its sources. First of all, there is freshwater. Out of all the water on the planet, only three percent of it is fresh, and only one fiftieth of one percent is readily available. Freshwater is not pure in that it contains minerals and other particles. There are numerous plants

Eventhough this book was written in the 1960’s, Erhlich still brings up many points which are still valid in today’s society. Environmental science often is not thought of by the public or the government, let alone the problem of human overpopulation, so this book served as one of the first looks into the issue. Environmental activists are often shunned as bein

The history of the expansion of the American frontier has been one mired in controversy. Historians, such as Frederick Turner, have always referred to American expansion and the Western frontier as the settlement of an untamed wilderness. This view, however, is false. Long before Columbus even reached the “New World” a vast civilization, comparable to that of Europe, had established

Chemistry: Water Pollution Phosphates in Water Pollution Phosphates may be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertia

Acid Rain
Acid Rain Acid rain forms when sulfur and nitrogen dioxides combine with moisture in the atmosphere to produce rain, snow, or another kind of precipitation. This kind of pollution may also be suspended in fog or deposited in a dry form. Acid rain is most common in North America and Europe. Acid rain has also been detected in other areas of the world such as tropical rain forests of Africa. Canada has placed limitations on the sulfur emissions. The United States has not, so the emissions may stil

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

Genetically Modified Foods: to Eat or not to eat Abstract Genetically modified (GM) foods have been around for quite some time. Chances are, just about everyone has eaten some type of GM food product. With the new and developing technologies that the biotechnology industry has to offer, the GM food market has risen in leaps and bounds. A genetically modified food is a food that has had its genetic make-up altered in some way by DNA technology. It can involve the transfer of genes from one organi

Global Warming Global warming occurs when the levels of greenhouse gasses rise and less infrared light, or heat, escapes the earth's atmosphere. Thus, the temperature experienced on Earth begins to rise. Climate change is a part of the Earth's history. There have been dramatic fluctuations in overall average temperature for the past 150,000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with carbon dioxide level

Global warming the most important environmental problem facing Canada
Global warming, the most important environmental problem facing Canada, is caused by gases in the earth’s atmosphere that trap enough of the sun’s heat to keep the earth’s surface, on average, at about 15oC , and provide the climate that we enjoy today. There is growing evidence that gases emitted from man’s activities are increasing the atmospheric concentration of these greenhouse gases (GHGs). There is also evidence that this is causing the earth’s average temperature to rise and change the
