2.0 Deforestation
2.1 Introduction
Forests are areas where trees are dominant vegetation. They include closed canopy forests, where leaves and twigs of adjacent trees touch, and open woodlands, where only some leaves and twigs of adjacent trees overlap. Deforestation is the irreversible destruction of native forests and woodlands. Today there is much concern with the sustainability of the planet’s biological resources, particularly our forests. However, we seems to be destroying them by harvesting them faster than they can regrow. For example, between the year 1840 to 1920, 19 million acres of white pine forest were logged in the state of Michigan alone in the United States. Those who started logging believed that they would never run out

However, it is now concentrated in the developing world, which lost approximately 494 million acres from 1980 to 1995. Many of these forests are in the tropics, mountain regions, or high latitudes, places difficult to exploit before the advent of modern transportation and machines. The problem is especially serious in the tropics because they have high human population growth. For example, fire-related deforestation rose sharply in Indonesia in 1997. Estimates of forests destroyed in 1997 range from 370,500 to 741,000 acres. Other areas where tropical deforestation is a major concern include the Amazon basin, western and central Africa, and Southeast Asia and the Pacific regions, including Borneo, the Philippines, and …show more content…
Forests are a global resource, so logging forests in one country can affects other countries. For example, since 1950, erosion due to deforestation has caused the loss of 1.4 billion acres of soil worldwide. Heavier flooding in India’s Ganges Valley has caused $1 billion a year in property damage and is blamed on the loss of large forested watersheds in other countries. Nepal, one of the most mountainous countries in the world, lost more than half its forest cover between 1950 and 1980. This cutting destabilizes soil, increasing the rate of landslides, amount of runoff, and sediment load in streams. Mmnay Nepalese streams feed rivers that flow into India. The loss of forest cover in Nepal continues at a rate of about 247,000 acres per year. Reforestation efforts replace less than 37,050 acres per year. If present trends continue, little forest land will remain in Nepal, thus permanently impacting India’s flooding

    Forests still cover about 30% of the world’s land area, but forests the size of Greece are lost each and every year. At this constant rate of deforestation, the world’s rain forests could entirely be wiped out in a hundred years. It is not just humans that will experience the consequences of deforestation, as for many plants and animals it will be the catalyst for their education. In Asia alone, deforestation is expected to result in the extinction of 13%-42% of the regional species population (“Introduction: Global Deforestation Issues” 2). Deforestation happens for numerous reasons, some are that trees are cut down to be used or sold as fuel or timber.…

    One of the biggest threats the world faces is the continuing destruction of our environment. Among the many ways that we as human destroy the environment deforestation by far has the most impact. Deforestation is a process by which forest are cleared in order to use the land for alternative purposes. Many may not think that losing a few trees will hurt anyone, however the fact of the matter is the impact effects all of us in a negative fashion. Trees are essential to life on earth.…

    The sheer amount of carbon released into the atmosphere is dooming future generations at an immense pace. Every year, almost 1 billion tons of carbon enter our atmosphere as a result of deforestation (Bradford). Global warming will only get worse as time goes on, but the speed of it can be reduced. If countries choose to plant more forests and cut down fewer trees, more carbon will be retained inside them. As global warming intensifies, the risk of forest fires increases significantly (“Deforestation.”).…

    The Climate & Weather Webpage states, “It is estimated that more than 1.5 billion tons of carbon dioxide are releases to the atmosphere due to deforestation, mainly the cutting and burning of forests, every year,” (Characteristics of World Weather and Climate ). Not only are we removing the only thing that absorbs CO2, but we are also piling even more into our air. If we continue the permanent damage of deforestation, we must expect the CO2 build up and imbalance to affect our environment that we live in. The major cutting down of trees must come to a stop because of the loss of many species. The growing population increases our wants for resources, but people do not realize the magnitude of extinction we are causing because of our wants.…

    People get their everyday items from trees. According to the article, Deforestation by World Wildlife Fund, “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.” This explains that deforestation is unnecessary since it’s more a lot more people can benefit from the forest than deforestation. It’s where some of the things we need are there. Also, later in the article it states “Deforestation comes in many forms, including fires, clear-cutting for agriculture, ranching and development, unsustainable logging for timber, and degradation due to climate change. This impacts people’s livelihoods and threatens a wide range of plant and animal species.…

    Depleted biodiversity • An approximation of eighty percent (80%) among all worlds’ documented species can be tracked and discovered in tropical rainforests-One of the types of forests that are most often exploited and having deforestation activities. • When the species lose their natural habitat, they often can sustain their life in the remaining small parts or fragments of forested land. • This also makes them more vulnerable and approachable by poachers. • This will cause the population to quickly deplete and shrink. For some organisms that fail to reproduce faster in order to compensate the loss, will end up in extinction.…

    He then added that the huge demolition of the forest calls for intervention by the younger generation that is coming up. In terms of the loss of major forests which is also known as old- growth forest, Nigeria still has the highest deforestation rate ion the globe (FAO, 2005). Nigeria lost 55.7percent of her major forests. According to (FAO), about 6million hectares of the world major forest is still lost per annum. This is very vital because major forests are taken as the most biologically diverse ecosystem on the…

    Bark beetle outbreaks are often fueled by drought and fire-damaged trees, killing more trees and exacerbating the effects of climate change (CFPC 2015). This paper will be focusing on the decline of one of California’s most abundant species, the Ponderosa pine (Pinus ponderosa). Ponderosa pine trees have a wide range and can be found throughout the western United States, southern Canada, and northern Mexico (Little 1971). Here in California they primarily occupy mountainous regions but have been found in elevations ranging from sea level to 10,000 ft. depending on latitude (Oliver and Ryker 1990). Ponderosa pines are susceptible to further decline as we continue to see increases in temperature and drought in California.…

    However, in comparison to the rest of the world, it is still happening at alarmingly high rates. According to Niki De Sky, a scientist researching the continents deforestation “pasture is by far the prime driver of deforestation. And this is a South American phenomenon – In Southeast Asia and Africa, crop agriculture plays a much bigger role than they do here” (qtd, McGlennon 1). Pastures account for nearly eighty-two percent of deforestation throughout the continent. Other smaller scale deforestation can be attributed to logging and…

    However, researchers claim that the animals lost to date are just one-fifth of those doomed to die. According to scientists, deforestation has cleared so much land that 38 more species are likely to become extinct in coming years, including 10 mammals, 20 bird species and 8 amphibian species. Some species are killed off directly through the clearing of the forest, but many face a slower death sentence due to lower breeding rates and a higher competition for food. Robert Ewers, a science journalist, predicted future extinction rates, under the scenarios of “business as usual” to “strong reduction”, which would require deforestation to decrease by 80%. "For now, the problem is along the arc of deforestation in the south and east where there is a long history of forest loss.…
