The rain forest is possibly the most diverse environment in the world it contains 90% of the world animal and plant life and has weather that changes rapidly. But every minute acres of this forest are being cut down. Loggers are mainly after the trees like mahogany, which sell for more money, but in this process they cut down and destroy masses of other plant life.
They have tried to make logging more economic by using selective logging which is searching the forest for these good trees then cutting the specific trees down and dragging them out of the forest, but even this is damaging because to get the trees out they need to bulldoze a path in and out and often destroy more trees than they are selling.
In this essay I am going to express my views on deforestation. The Amazon rainforest is about the size of Europe and every day roughly 51. 8 square kilometres are cut down. So that’s 18,900 square km a year and that’s a lot.
One of the main reasons for deforestation is the actions of Brazil, in the 1970 – 80’s Brazil borrowed a large sum of money from MEDCs to develop their country they now owe these MEDCs ?50 billion a year and a further ?15 million interest every day. So to pay this back they need to use their main resource, which is their forest and the easiest way to get money out of it, is logging. A single mahogany tree is worth ?35,000 so they will need to get a lot to pay back the debt but for every mahogany tree that is cut down an average of 30 other trees are cut down.
So for brazil to earn ?1 million they need to cut down about 888 trees and to pay back their daily interest they need to cut down 13,320 trees a day, but how many trees will they need to cut down to make the ?50 billion they owe a year. An alternative to logging that still uses the forest is tourism they could take people for hikes through the rainforest and camp in it, they could teach people about different animals and show them species that they may not have seen before. They could also show they plants and how to use them like bush craft so they could learn a new skill that could help them in life.
But an idea that will drastically stop or at least lessen deforestation is that these MEDCs just drop the debt there is basically no way that Brazil will get enough money to pay them back and anyway The MEDCs don’t really need the money. So dropping the debt won’t make much difference. The Importance of Rainforest: Biodiversity Tropical forests cover only twelve percent of the land-area of the Earth, yet they are home to between 50 and 90 percent of the world’s species. Because of tropical deforestation, at least one species is disappearing every day.
This rate of extinction is now 400 times faster than at any other period in the history of the planet. Medicines Rainforests are a vital source of medicines. Today, less than 1 percent of the world’s tropical forest plants have been tested for pharmaceutical properties, yet a quarter of all modern medicines came originally from rainforests. Most were first discovered and used by indigenous people. Food Diversity Rainforests also offer a bounty of foods. Foods that we use today which originated in rainforests include coffee, cocoa, many fruits and nuts, spices, rice, and other products such as rubber, gums, resins, dyes, tannins and cane.
Of an estimated 75,000 edible plants found in nature, only 150 enter world commerce and only 20 (mostly domesticated cereals) stand between human society and starvation. This makes modern agriculture extremely vulnerable to pests, diseases and changes in climate. Genes from wild plants can be used to fortify modern varieties against this vulnerability. Without rainforests, this opportunity is lost, as is the chance to develop entirely new food plants. Climate Tropical forests regulate global and regional climate-systems by acting as heat and water pumps.
They release moisture into the atmosphere which returns to the ground as rain. When the forest is cleared, the water cycle is disrupted, temperatures increase, droughts become common, and eventually deserts may form. For example, the drought in the Sahelian belt (south of the Sahara Desert), has been attributed to deforestation in West Africa. Estimates suggest that tropical deforestation currently contributes at least 19% of greenhouse gas emissions. Tropical forests have been described as “the lungs of the Earth”.
However in mature primary forest, storage and release of carbon is in balance. Carbon-dioxide consumed during photosynthesis is equalled by that released when organic matter decays. A standing forest acts as a store or sink of carbon. On the other hand, when forests are burned or logged and the debris left to decay, carbon dioxide is released into the atmosphere. Prevention of Flooding, Soil Loss and Siltation Tropical rainforest soils are very old and have been impoverished by eons of high rainfall leaching away their mineral nutrients.
The forests have evolved to cope with this by rapidly recycling nutrients. Forest litter, and the droppings and remains of animals are quickly decomposed, releasing nutrients for uptake. Most nutrients are only available from this decomposing layer, so many rainforest trees are shallow-rooting and have buttresses for support. Rainforests act like giant sponges, soaking up moisture, and then releasing it slowly. This moderates the flow of rivers thus preventing flooding and ensures that rivers and creeks continue to flow during periods of lower rainfall.
When the forest is cleared, rain falls directly onto the compacted soil, often resulting in serious soil-erosion, siltation and flooding. Major floods in southern Thailand, Bangladesh and the Philippines have been attributed to forest clearance. Once the nutrient recycling-system is broken down, the land can’t support human activities such as cattle ranching for more than a few short years. Tropical Rainforests are Absorbers of Carbon Dioxide Scientists now say that the rainforest ecosystem in the Brazilian Amazon is a net absorber of carbon dioxide, and therefore helps to protect the earth against the greenhouse effect.
This means that primary forests may be more important as carbon sinks than either young secondary forests or plantations. Over the past few years, the forest industry has argued that plantations are needed to absorb carbon dioxide, and plantations are still being established in place of natural forests in countries such as Indonesia and Chile. This is why I think that the rainforest of the world should be protected and everyone should do whatever they can by all means to help this beautiful rainforest of ours, which is a gift and should not be wasted.
