Rain Forrsest Essay, Research Paper


Rain forests may be grouped into two major types: tropical and temperate.


Tropical rain forest is evergreen trees that form a closed canopy, below


which is found a zone of vines and epiphytes where plants grow on trees, a


relatively open forest floor, and a very large number of species of both


plant and animal life. The largest trees have buttressed trunks above the


continuous canopy, while smaller trees form a layer of more shade-delicate


species beneath the upper canopy. The maximum height of the upper canopy of


tropical rain forests is usually around 100 to 165 ft, with some individual


trees rising as high as 200 ft above the forest floor. Conifers such as


redwood and Sitka spruce tend to predominate in North America, while their


counterparts in the southern hemisphere include various species of


eucalyptus, Araucaria and Nothofagus. Th rain forest is home to many species


of rare animals and plants. In the past and present history it has also been


the home of over one hundred and twenty over the counte


r prescriptions. All of this information has brought up the question that is


on many minds, Should economic organizations, buisnesses and individual


governments be allowed to continue the use and at times the abuse of the


brazilian rain forest? Is economic advancement more important than the


preservation of the rainforest. This is why we are the government has called


on us. To find the facts and give it how it should be.


Medicinal uses of the rain forests are a huge part of everyone’s lives.


The rain Forrest has over 120 over the counter prescriptions and has made


over


12 billion dollars in sales. They say that the tropical rainforests cover


seven percent of the earth and hold just about half of the world’s an

imals.


Also there is data that there may be about ten percent of useful Amazon


plants now, and scientist’s think that also there may be a cure for the AIDS


virus. These are some of the medicines that come from the rainforest. Like


the drug called Quinine, which comes from the bark of quinine tree, which


fights malaria. Not only do the plants have cures, but the animals there too


have some medicine in them. Like the Brazilian pit viper, which can help


solve blood pressure. The drug is called Capoten; the venom from the pit


viper is the main ingredient in the drug. Right now in the Brazilian


rainforest there are currently 121 different drugs being produced and being


sold all over the world. The United States cancer society has discovered that


three thousand plants that are found in the rainforest are currently active


against cancer cells. Twenty five percent of ingredie


nts in today’s cancer fighting drugs come from organisms only found in the


rainforest. Some of these help you recover leukemia; they are Vincrstine, and


Periwinkle.


More than 100 endangered species are dying each day and they estimate 40,000


will be dying each year in the year 2000. One of these species is the Jaguar


who is being hunted for their beautiful fur. Another reason for this is


because they are slowly becoming more rare by the year. Hunter’s obsessions


for the rarest animal are becoming worse. One more reason is because of our


population, we are taking up more room in the world and we are driving over


looked animals out of their homes, and with out their homes it makes it


extremely difficult to get used to a new one. We need all of the animals in


the world because they all have a part in it to help everything and everyone.
