Destroying Our Rainforests
Every day an average of two football field sizes of precious rainforest are torn down, killing millions of animals and destroying valuable pharmaceutical plants. A huge amount of these animals and plants have never, and will never be discovered. Experts say, "Close to eighty percent of the terrestrial species of animals and plants are to be found there [in the rainforest],." As people tear down the rainforests they are affecting the ozone layer, and disrupting the process that lets plants fight the deadly amount of pollution the world produces every day.
Over three thousand plants found can help the fight against cancer. Seventy percent of these plants are found in the rainforest. Periwinkle is a very essential plant that produces the drug Vincristine that is the most powerful cancer-fighting drug that has been discovered as of today. Scientists say, "Vincristine is used as a part of MOPP chemotherapy regimen, and has helped increase the rate of remission in acute childhood leukemia from twenty percent to ninety percent.." The periwinkle plant is only found in rainforest regions. Imagine not having access to this drug anymore because all of the rainforests in the world have been torn down. The world may never find a cure to cancer, one of the most common and deadliest diseases known to man if the rainforests and the plants within them continue to be destroyed.
There are thousands of other plants in the rainforest that have not been discovered yet. Specialists say, ."..sixty five to seventy-five percent of higher plant species are indigenous to rainforests,." If the populace tears down all of the rainforests, only fifteen to twenty-five percent of the vital plants we depend on will be left in the world. Cornell biologist Thomas Eisner estimates that "less than two percent have been explored for their medicinal potential,."
Every day the world looses an average of one hundred thirty seven species of animals in the rainforest due to the demolition. At that rate, the planet looses fifty one thousand and five species a year. Most species of these animals will become extinct before they are even discovered. The world then looses the chance to learn about all of the amazing and fascinating animals that live in the canopies of the rainforest, because of the destruction.
The mass murder of these helpless and innocent animals is incredibly unjust and cruel. Fifty one thousand and five species of these innocent creatures are killed per year, just so that the world can obtain wood.
The Brazilian Rainforest is one of the most unique, vast, and diverse regions of the world. To get a general idea of the diversity of the Rainforest, it makes up a total of one-third of the world forests (more than four million square kilometers), it contains half of the total number of named species in the world (eighty-thousand plant species, 1,500 fish species, and one-forth of the 8,600 bird species), and is the world largest holder of genes (Library 138-139). To say the least, the Brazilian Rainforest is one of the most important natural resources we, as humans, know. It would seem that this knowledge, alone, would also make the Brazilian Rainforest one of the most protected land areas on Earth as well. However, the situation is quite the opposite. The Brazilian Rainforest has been greatly degraded by deforestation since the 1960 , which has led to numerous negative effects both environmentally and socially. This paper introduces the events that opened the door to deforestation, the most immediate causes and effects of deforestation in the Brazilian Rainforest, and my two-part solution to the problem of deforestation.
Of all of the issues that effect the planet Earth from a Global Change standpoint, one of the most visible and highly publicized is the issue of rainforest destruction. The loss of this emerald on the planet's crown will end life as we know it, if something is not done...
to cut down trees in rainforests? Rainforests are meant to be beautiful, peaceful places where people can visit, but no, the trees. are cut down for wood and paper. Think of all the hundreds of species. who live in the rainforest, who are pushed out of their homes.
This process also produces high levels of oxygen that help to support life around the world. Coupled with the high levels of rainfall that benefit the water cycle, the rainforests are an integral part of the many systems that exist. These forests contain a wide variety of plants that a source of different chemicals that are used to create medicines. The degradation of these areas could potentially lead to the loss of medicines that could cure some of the deadliest diseases and illnesses that Governments in these countries need to stop thinking of forests as a renewable resource. The rate at which they are harvesting these areas drives them beyond the boundaries of sustainability.
Extinction is no longer just a natural process. It is an enemy, slowly changing our world into a barren wasteland where life is as rare as a flower in the Arctic Circle's winter. The wolf, the tiger, the caribou, the elephant, the bison, the cheetah, the sequoia cactus, the redwood tree – all of these and so many more things are on the verge of disappearing from our planet forever. Extinction is the most pressing environmental issue of our time, because if it continues the way it is going without anything being done to counteract its causes and consequences, there will soon be no environment left for there to be debates about.
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.
On average millions of hectares of forests are destroyed each year resulting in severe consequences that will affect not only our lifestyle, but also all the animals with which we share our planet. Many species of animals and plants will become extinct and if we continue with the destruction of our forests, earth will be unable to sustain life.
On average 18 million acres of forest are lost every year due to deforestation. That’s 49,315 acres per day, 2,054 acres per hour, 34 acres per minute and .5 acres per second. If we continue at this rate there will be no rainforest throughout the world within a hundred years. Deforestation results
More than one hundred and fifty acres of rainforest are lost every minute of every day. Cattle ranches make up 80 percent of destroyed rainforest land. Runoff from these ranches contaiminates rainforest rivers, which further harms the already fragile ecosystem. This is just a small glimpse of what would happen if all the rainforest was removed. The well being of the earth in the present and the future makes it essential that we as humans protect the Amazon rainforest.
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.
The rainforests contain thousands of different resources, plants, and animals. There are also about 18,000 new species found each year; if we cut down and destroy these rainforests then we will not discover most of these intriguing animals. If we demolish rainforest, then we will be destroying our chances of finding new plants, which could make new medicines which would make cures for diseases that are incurable . For example, if a new undiscovered species of plants or animals were living in the rainforest, they would be nonexistent because we cut down and destroyed all of their homes. They will eventually die since they have nowhere to live.
Simply speaking, rainforests are basically the foundation of the earth. The most important role that rainforests play is ‘the lungs of the earth’. This is extremely vital to the earth’s survival as the trees and plants absorb carbon dioxide which they use to help grow and let out oxygen which we need to live. This system is known as the carbon-oxygen cycle and with numbers of rainforests declining, it is highly threatened. The largest rainforest in the world, the Amazon, alone is known to produce half of the world’s oxygen. A break down in the carbon-oxygen cycle means that we will not only have less oxygen, but an increase in carbon dioxide which eventually leads to global warming. This occurs as carbon dioxide traps heat which actually keeps the earth warm, with the right amount of carbon dioxide that is. This is called the greenhouse effect and occurs naturally however due to decreasing number of trees, there is more carbon dioxide than needed which traps extra heat making the earth hotter than needed, this is known as global warming which also causes a rise in sea level.
In recent years, a lot of attention has been drawn to the undeniable fact that we are rapidly depleting our natural resources, and destroying the environment around us. More and more people are coming to the realization that we must work to preserve our Earth's natural beauty and resources for future generations. One of the biggest issues that our world, as a whole, faces, is the destruction and deforestation of our rainforests. These very same rainforests that we are chopping, and burning down, are home to the most wildly diverse populations of plant and animal species, many of which cannot be found anywhere else on Earth! Three centuries ago, 14% of our planet was covered in rainforests.
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
The Disappearing Rainforests Conserving the rainforest is a global issue of great importance. Tropical rainforests provide a habitat for animals, a unique ecosystem for vegetation, and an abundance of resources for humans, yet they are being destroyed at an astonishing rate. Experts estimate that if these endangered territories continue to be consumed in this manner, no more will be standing in forty years (Rainforest). Examining the social, environmental, and economic costs of the continued destruction of the Earth's tropical rainforests will prove that deforestation for short-term profit is ultimately not viable.
