Rainforest Destruction
Rainforests cover less than two percent of the Earth’s surface yet they are home to some forty to fifty percent of all life forms on our planet: as many as 30 million species of plants, animals and insects. The Rainforests are quite simply, the richest, oldest most productive and most complex ecosystems on earth. As biologist Norman Myers says, “Rainforests are the finest celebration of nature ever known on the planet and never before has nature’s greatest orchestration been so threatened.”
The Rainforests are very important to the world for many reasons, most of them being very simple. One of the major reasons is that the plants in the forest turn carbon dioxide into clean air, which helps us, fight pollution. Also, by absorbing carbon dioxide, the rainforests help deter the greenhouse effect.
The plants and animals of the rainforest also provide us with food, fuel, wood, shelter, jobs and medicine. “Imagine losing the potential cure for cancer or AIDS that might have been found in an undiscovered plant from the rainforest.” (Tropical Rainforest Coalition, 1996) “The vine Aucistrocladus koropensis may be effective in treating AIDS; we can only guess what other beneficial plants may be destroyed before we find them.” (Allo, 1996) It is repeated often that the rainforest contains important plants that will cure the worst diseases of today. Although there is scientific proof of its value, the rainforest continues to disappear. “In every sense, a standing rainforest supplies more economic wealth then if it were cleared…yet deforestation continues at an alarming rate.” (Tropical Rainforest Coalition, 1996)
Tropical rainforests are found in eighty-five countries around the world. “Ninety percent of these forests are concentrated into fifteen countries, each country containing over ten million hectares each.” (Malaysian Timber Council, 1995) Tropical rainforests are located around the equator, where temperatures stay above eighty degrees Fahrenheit year round. These forests are very dense and damp. “Although tropical rainforests cover just seven percent of the Earth’s surface, they can provide habitat for between fifty to ninety percent of its plant and animal species. In 1990, tropical rainforests totaled some 1.7 billio...

...ese rainforest species have never even been seen. “Scientist estimates an average of 137 species of life forms are driven into extinction everyday or 50,000 each year.” (Myers) While extinction is supposed to be a natural selection this is purely human induced. Quite simply when habitat is reduces, species disappear.
All in all, the tropical rainforests are one of the Earth’s greatest assets. We need to preserve this valuable resource. It could provide the cure for cancer or AIDS but we’ll never know if we continue to deforest it. There are now ways to fight back against the destruction of our rainforests. Many people now boycott; for example not eating fast food because the meat come from rainforest cattle because they are cheap, or by not buying furniture made from rosewood, mahogany, ebony, and teakwood, because they most likely came from the rainforest as well. People can also adopt an acre of tropical rainforest for only 45 dollars. Rainforests are very complex ecosystems and have many untapped resources which we have barely scratched the surface on. Preservation of the rainforest is essential for our well being and the well being of the future.
Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter (drug war facts, Page 1).
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%.
Rainforest can be very moist, hot, and humid due to all of the rainfall. The average rainfall is

While reading Michelle Gardner-Quinn’s essay about reverence for all life I was truly touched. I found this essay to be vastly eye-opening and incredibly inspiring. When considering which biome is my personal favorite, I come to the conclusion that the tropical rainforest touches my heart. I have had the opportunity to see the beautiful tropical rainforest, and it is an experience I will never forget. Some may say that the tropical rainforest only has humidity, but that is so far from the truth. The tropical rainforest is a biome filled with magnificent plants and animals. It is even said the tropical rainforest biome houses half of the earth’s population of plants and animals. This statement to me relates back to Michelle’s statement about
A tropical rainforest is an ecosystem type which occurs roughly within the latitudes 28 degrees north and south of the equator. The forests are dominated by tall, closely spread trees, with a predominately continuous canopy. This ecosystem experiences high average temperatures and a significant amount of rainfall during the year. Elements of the biophysical environment of the biome and their interaction with each other Ecosystems develop in response to the interactions between biotic and abiotic components. Certain conditions in the atmosphere, hydrosphere, lithosphere and biosphere must occur for the formation of tropical rainforests.
The rain forests are incredible places. They only cover 6 % of the world’s surface however they have more than ½ the world’s plant and animals species. A rain forest can be described as tall and thick jungles. There is a reason behind the forest being called a “Rain forest” and it is because the high rainfall it gets per year. On average, 50 to 260 inches of rain falls yearly. The temperature in a rain forest rarely gets higher than 34 ºC or drops below 20 ºC. The average humidity in a rainforest is between 77 to 88%. Rainfall is often more than 100 inches a year.
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 planet's 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. In its current state, the Amazon is losing land equal to the size of the state of Delaware every year.
The natural resource of wood is being used at an unsustainable rate, with minimal effort to change societal views on the depletion of this valuable natural resource. Much of the wood we use today comes from old-growth tropical forests, and in many regions it is harvested illegally. Recently in England, it was revealed that the major department store, Marks&Spencers, made much of its garden furniture out of Nyato wood which was logged illegally from Indonesian rainforests. Looking at this problem from a micro-level orientation, we can clearly see how the actions of individuals in both Britain and Indonesia affect one another.
The Human Impact on Rainforests Human Impact on Rainforest is it a necessity? Rainforest are the beautiful gift of Mother Nature. It consists of the most magnificent species and plants in the world. 4.2% of the world’s animals live in the rainforest. This statistic it self shows how bad it would be to destroy such essential part of the worlds biodiversity.
...later time. Though it is simply impossible to know what the ultimate effects will be on our long term survival as a species, it is important to bear in mind that, once a species has been eliminated through extinction, it cannot be brought back. So, for the overall health of our rainforests, their biodiversity, and the limitless potential contained therein, it is crucial for us, as humans, to make as honest an effort as possible at their preservation.
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.
Tropical rainforests have many species of plants and animals. They are very interesting and many scientists today study it. Rainforests are an important part of our environment and it is important for us to protect it. That’s why we have to stop global warming.
The Amazon Rainforest is the world's largest tropical rainforest that we have today on our planet. It covers a wide range expanding almost entirely across from East to West of South America. It is most famous for its broad biodiversity and includes the famous Amazon River that is home to rare and diverse species. Today, the Amazon Rainforest is under threat of complete deforestation and has greatly lost more than half of its tropical rainforest due to cattle ranching, soy bean farming, sugar cane plantations, palm oil and biofuel agriculture. The indigenous people are doing their best to fight against the government to protect their land and conserve the rainforest but without capital finance, it is seeming to be an impossible project.
