Rainforest's Causes Carbon Dioxide example essay topic

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 rainforest's 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 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 rainforest's 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 rainforest's are located around the equator, where temperatures stay above eighty degrees Fahrenheit year round. These forests are very dense and damp. "Although tropical rainforest's 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 rainforest's totaled some 1.7 billion hectares". (Forest Alliance of British Columbia, 1996) The cause of the destruction of the rainforest was put very simply by the Forest Alliance of British Columbia (1996): "The global population has more than tripled this century, and will continue to grow for the next 50 years, particularly in developing countries. World population is expected to reach ten billion by 2050".

Because the number of people living on the planet increases every year, the number of forest products needed also increases, forcing temperate and tropical rainforest's to be cut down. Traditional there were three major causes of destruction to the rainforest: farming, ranching, and logging. Farmers in the rainforest countries are often poor and can not afford to buy land. Instead, these farmers clear rainforest land to grow their crops. Because tropical rainforest soil is so poor in nutrients, farmers can not reuse the land year after year. The farmers just keep clearing more land year after year, destroying the forest piece by piece.

Ranching also causes destruction of the rainforest's. Ranchers clear large areas of forest to become pastures for cattle. This land does not cost them very much, so they can raise and sell more cattle. The third major reason for deforestation is logging. Trees from the rainforest are used for building houses, making furniture, and providing pulp for paper products, such as newspapers and magazines.

When trees are pick from the forest it opens up the canopy allowing for the plants and forest floor to dry out and become more susceptible to fire. Rainforest that was chopped down can grow back over time, but they will never have the same variety of plants and animals they once did. The Destruction of these rainforest's causes carbon dioxide to be released, which in turn allows the greenhouse effect to occur. The greenhouse effect raises the temperatures all around the world, and can cause ice caps to melt. When ice caps melt, the sea level rises, causing major flooding around the world. Also the raise in atmospheric carbon dioxide factors in species extinction.

Most of the global warming increases when a forest is burnt and carbon dioxide is at its highest. The rate that the tropical rainforest's are being destroyed at is astonishing. "2.4 acres per second are being destroyed, which is the equivalent to two U.S. football fields; 149 acres are being destroyed per minute; 214,000 acres are being destroyed per day which is an area larger than New York City; and in one year 78 million acres are being destroyed which is an area larger than Poland". (Myers) Economically destroying the tropical rainforest's isn't as profitable as letting them be and properly harvesting their fruits, latex and timber. The tropical rainforest is worth, "$6,820 per year per hectare if intact forest is properly harvested; $1000 per year per hectare if clear-cut for commercial timber; and $148 per year per hectare if used as cattle pasture".

(Myers) The rainforest also provides us with some of the most valuable resources we have today like medicines, it provides us with twenty percent of the world's oxygen supply and one fifth of the worlds fresh water supply is located in the Amazon Basin. The rainforest is also home to countless species of plants, animal, and insects. It's said that there are over 30 million different species in that call the rainforest home. Five out of six of these 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 rainforest's 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 rainforest's. 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..
