The Destruction of the Rainforest
The purpose of this paper is to inform the reader of the destruction of the rainforest. In my paper I discuss many aspects of the rainforest. I explain what the rainforests are, and give a brief summary of the importance of the rainforests. I also give a description of the destruction of the rainforest, and how a person can help to save the rainforest.
The rainforests are disappearing acres per minute, a number that grows so quickly it would be impossible to cite here because it would be outdated within a week. The rainforests are home to over half of the entire species of the world, which are being destroyed with the rainforests. Unlike the rainforest itself, which may appear to grow back, it will never be the rainforest it once was, and the species that were killed will never return again. Many of the species that have not yet been discovered may very likely cure cancer, AIDS, and many other diseases and viruses of today. If the rainforests disappear so will most of the population of the world. By the end of my paper the reader will know more about the horrifying destruction of the rainforest and how we can all work together to stop it.
There are two different types of rainforests: tropical and temperate. Tropical rainforests are found in 85 countries around the world. They are located near the equator, where temperatures stay above 80 degrees Fahrenheit year round. These dense, damp forests occur in Latin and South America, Africa, and Southeast Asia. Although they (tropical rainforests) cover just seven percent of the earth’s surface they can provide habitat for 50-90 percent of its animal species. In 1990, tropical rainforests totaled some 1.7 billion hectares (Forest Alliance of British Columbia, 1996). Half of the world’s rainforests lie within the borders of Brazil, Indonesia, and Zaire.
Tropical rainforests have 3 layers: the forest floor, the understory, and the canopy. The forest floor has soil and is home to mainly insects although large mammals like gorillas and jaguars are also found there. Many smaller animals, including anteaters, lemurs, and tree kangaroos live in the understory. This is also where many small trees and shrubs are found.

Smallpox has been believed to be a prominent killer for thousands of years. Before 900 AD smallpox and measles were easily interchangeable to many physicians. These two diseases possessed similar symptoms, such as fevers and rashes, making it very difficult to distinguish between them. It was not until the Persian physician, Rhazes Ar-Raz Abmiz, that measles and smallpox were able to be clinically distinguished in 900 AD. Much later in 1751, Thomas Sydenham found further differentiating characteristics between the two diseases(Aufderheide, 202). Through the years, with its many outbreaks in varying areas across the planet, smallpox claimed millions of victims. Many rulers and soldiers were killed by this incredibly infectious disease. To prevent and hopefully stop the increasing numbers of deaths due to smallpox, many physicians slaved away to invent and find a cure for this disease. The first effective method of prevention was called variolation. Variolation was later modified and improved with vaccinations(Hopkins, 15). Today wild smallpox is no longer a risk. The last natural case of smallpox was reported in Somalia in 1977. While the last reported death due to smallpox was reported to be a year later in the UK(McNeil, 165). Smallpox is not completely out of the picture. After the 2001 attacks with anthrax, a strong paranoia of smallpox being used as another possible mean of bioterrorism has arisen(Oldstone, 32).
Tropical rainforests are an extremely unique and diverse ecosystem that are located around the earth’s equator. They once covered roughly 7% of the world, but due to human encroachment that has dwindled to just 2%. It is a highly moisture rich environment that typically receives anywhere between 60 and 400 inches of rainfall annually and average humidity ranges from 70 to 90%.

When we think about art there are many mediums used to express how artist feel. Some artists express themselves using pictures, music, or films. When you think of specific time periods the art work of that period expresses the overall emotions of the people, and we can learn a lot about a time period by studying the art of the time. The time period that most expresses is the Renaissance.
The Amazon Rain Forest Is in Danger of Being Destroyed" by Devadas Vittal. Rain Forests. HaiSong Harvey, Ed. At Issue Series. Greenhaven Press, 2002.

Back in the ancient’s time during the pre-historic era as far as 1000 AD this disease was not very much known to people but have said to be found on an Egyptian Pharaoh Ramesses V mummy who died in 1157BC (Henderson, Fenner, Arita, Ladnyi, 1988 p 209-210). There was evidence of pustule eruption and rash that have been seen on the mummy similar to the description of a variola virus. Part of the idea of where this disease came from is unknown and where the origin of this disease is very much not clear. This disease that is known to be contagious and deadly at times is called smallpox. The early civilization had believed smallpox was originated from Africa and soon had spread though out the world like China and India (Fenn, 2003).
The first recorded smallpox outbreak occurred in 1350 BC during the Egyptian-Hittite war. The illness was passed from Egyptian prisoners to the Hittite population affecting both soldiers and civilians. Although it wasn’t until the late 1600’s that people in Europe and Asia accidentally discovered that those infected with smallpox through a scratch on the skin, suffered from a less severe form of the disease than those who contracted it through the respiratory tract. In the early 1700’s doctors began to store samples of smallpox pus and scabs in jars. If an outbreak occurred the doctor would make a small cut in a person’s arm and smeared the pus into the wound. This process of intentionally infecting a person with the smallpox virus in order to make them immune to the disease in the future was called inoculation.
As early as AD 100, in Rome smallpox ravaged for 15 years, causing two thousand deaths daily. The disease spread throughout Europe, Asia and Northern Africa from the 12th through the 15th century. Colonists and explorers from E...
Until its eradication, smallpox was a disease that had been ravaging the human race for a very long time. It emerged as much as 10,000 years ago, probably in the Nile Valley and what is now the Middle East. This emergence occurred around the time that humans began to create farming communities and turn away from nomadic existence, thus allowing the smallpox virus a chance to move from person to person (Ogden 2). Since that time, outbreaks have occurred in all different regions of the globe, although the disease was not introduced into the New World until 1518 when a Spanish ship landed on the island of Hispaniola, thus wiping out half of the population. The Spanish sailors had previously been infected by a strain of the smallpox virus and were therefore immune. The natives, however, had never been exposed to the virus and their bodies were unable to fight it off at all. It is thought that as much as 90 percent of the native populations of the New World were killed by smallpox in conjunction with the other previously unseen diseases that were brought over by explorers (Ogden 3).
Smallpox is an very contagious disease that lasts for about 41 days, 24 of those days are mildly to severely contagious. Variola passes from person to person through contact, prolonged face to face contact, contact with body fluids or scabs from pustules, and in extreme cases the pathogen can become an airborne pathogen. The smallpox virus is passed from human to human and it is not known if any other animals and/or insects can directly pass the variola virus to humans. There have been many cases where people have confused the variola virus with other viruses. For example S Scar Rickettsiella is an deadly disease that is nearly identical to smallpox but it is not as deadly and somewhere on the body a little scar shaped like a S (about the size of an mole) appears on the body. There is one live culture of smallpox kept in America in Atlanta, Georgia in an very secure facility. There is also one kept in Novosibirsk, Russia. Many world leaders fear that the next weapon will be biochemical terrorism. Smallpox can become an airborne pathogen which could cause the greatest amount of damage in a terror attack. From the time the virus enters into...

Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.
In South America lies the largest and most wondrous rainforest in the world, the Amazon Rainforest. This 1.4 billion acre forest represents over half of the planets remaining rainforests, and comprises the largest and most bio-diverse tract of rainforest in the world. Ten percent of all known species on the planet are found in this rain forest, most of which have yet to be discovered. For the past century, the Amazon has been gradually decreasing in size due to agricultural expansion, ranching, infrastructure projects, energy exploration and illegal logging. At its current state, the Amazon is losing land equal to the size of the state of Delaware every year. The destruction of this forest releases 340 million tons of carbon per year according to the World Wildlife Foundation, or WWF, which in turn cause climate changes everywhere around the world. Undiscovered species can hold the key to curing a plethora of diseases, but if those species become extinct those keys are lost forever. If nothing is done to prevent this, the world’s treasure trove of bio-diversity will cease to exist, creating irreversible damage to not only the South American people but also the rest of the world.
Adolescent despondency affects the way an individual sleeps, eats, the way they feel about themselves and those around them (“Side Effects of Untreated Depression”). This particular mental disease changes the outlook on a teenager’s view on themselves, loved ones, and their surroundings. Depression can be a responsive action to certain situations, such as emotional trauma, and stress. It can have devastating, and in some cases, life threatening, effects on younger members of society. Due to the fact that normal, unaffected teenagers naturally have fluctuating moods, it is much more difficult to diagnose depression at this age.
