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 very near future. Whether or not the pros
outweigh the cons will be hotly debated for years to come but the fact is that
deforestation is harmful to the environment and leads to declining wildlife
populations, drastic changes in climate and loss of soil.
The loss of forests means the loss of habitats for many species. Current
statistics show that as many as 100 species become extinct every day with a
large portion being attributed to deforestation (Delfgaauw, 1996). "Edge
effects" are the destruction or degradation of natural habitat that occur on the
fringes of fragmented forests. The effects for the animals include greater
exposure to the elements (wind, rain etc'), other non-forest animals and humans
(Dunbar, 1993). This unnatural extinction of species endangers the world's food
supply, threatens many human resources and has profound implications for
biological diversity.
Another negative environmental impact of deforestation is that it causes
climate changes all over the world. As we learned in elementary school, plant
life is essential to life on earth as it produces much of the oxygen that is
required for humans and other organisms to breathe. The massive destruction of
trees negatively effects the quantity and quality of the air we breathe which
has direct repercussions on the quantity and quality of life among both humans
and animals alike. With this reduced amount of vital plant life comes the
increase of carbon dioxide levels in the earth's atmosphere. With these
increased levels of CO-2 come unnatural changes in weather patterns both locally
and globally. "The removal of forests would ...
The atmosphere is divided into four layers based on their temperatures, the outermost region called the is located above the mesosphere and above this layer is outer space. The Greek name Thermos meaning "hot" shows that this is the hottest part of the atmosphere. Temperature here steadily increases with height, beginning at about 85 km (53 mi) a...
The global energy balance and atmospheric motion mainly determine the circulation of the earth's atmosphere. There is a hierarchy of motion in atmospheric circulation. Each control can be broken down into smaller controlling factors. The global energy balance is an equal balance of short-wave radiation coming into the atmosphere and long-wav...
In the United States in 1995 alone, 43,063 died from . It is the number two cancer killer and the number one cancer in females ages 15 to 54. On average if a woman gets this disease, their life expectancy drops nineteen and a half years. This cancer is within the top three cancers of all women above the age of 15, and comprises 6% of all health car...
An earthquake is shaking or trembling of the earth that is volcanic or tectonic in origin. "A broadly satisfying explanation of the majority of can be given in terms of what is called plate tectonics. The basic idea is that the Earth's outermost part also called the lithosphere consists of several large and fairly stable slabs of solid and relati...
Autumn, in a deeper sense, is a magnificent ending to an era. Although all the leaves fall and the sun fails to shine for as long each day as it did during the summer, the death of the cycle of the living seasons is spectacular. It brings vibrant color, tolerable weather, and the promise that it will return again in the spring. Like life, people sp...
is war fought with chemicals. The development of chemical weapons and defenses against these weapons are usually considered together in military training. These weapons can be designed to kill large numbers of people, disable them for a while, or destroy their food supplies. The weapons are usually effective without destroying property. Chemical ag...
As the millennium approaches we come closer and closer to what some say could mean the end of civilization as we know it. What is this great event that would have such an impact on the world that it could end civilization? The problem is a simple computer bug refereed to as the Y2K bug but its ramifications could be immense. This computer bug ha...
' work on planetary motion stood an a very high mathematical level for his times. His theory explained how all the celestial bodies move around the Sun. It took Nicolaus 30 years of mathematical research to form a theory about planetary motion. The three most popular instruments which used were quadrant, armilla, and triquetrum. All furnish so...
I believe human cloning is an interesting topic and could possibly be used for the good of society. Despite decades of speculation, there has been no human reproductive cloning. Research cloning, also known as embryo cloning or therapeutic cloning, is another form of human cloning that produces genetically specific embryonic stem cells. After many...
When many people thing of the United States, they envision a land of freedom, prosperity, and wealth. However, environmentalists see a different land, one containing six percent of the world's population, and yet producing twenty-five percent of the world's pollution. This is because much of our prosperity is direct result of our exploitation of...
Newspaper Article Essay: "In Layman's Terms" Authors of modern scientific journalism convey information to target audiences in differing formats, depending solely on the level of education of the audience and how the issue might affect their lives. As a result, publications come in two models: new, original articles, or reports based on existing pu...
Throughout the entire history of mankind, the technological advancements that civilisations have made have always been tied in with the development of energy sources. The first human energy technology was fire, along with human labour as the major energy source. This has bee supplemented by animals for agriculture and transportation since at least...
The environment can be something as vast as global weather patterns or as simple as the desert regions. With the advent of many technologies, the delicate balance of the environment has been upset (Elliot, 1961, p. 392). Strip mining, slash and burn farming, damming of rivers, and the extinction of many species of plants and animals have all lead...
Harvard University biomedical engineer David Edwards invented breathable vitamins as they get into the bloodstream faster than pills do. The product which Edwards created is called Le Whif. When you swallow pills, more specifically vitamins, the intestinal tract and liver degrade the active ingredients and slow down absorption into the body, but b...
