I-Overview of the deforestation phenomenon
a.Causes and history

Indeed, in Europe, medieval forests have been reduced because of the needs to food forges, chimneys, ovens… Moreover, the expansion of agriculture’s ground reduced 15% of the forests’ surface in the end of XIXth century. After, researches have been made in order to reduce deforestation. They allowed to profitable coal mining and to use fossil fuels. So since the end of XIXth century, forests increased again. In the 90, nearly 70% of deforested lands have been converted to farmland. For example, in tropical area, deforested lands are used for the cultivation of tobacco, soy and oil palm. Furthermore, the slash and burn agricultural technique is used, that is the land are burned to created more …show more content…
Indeed, soybean production and industrial-scale cattle ranching increase the phenomenon in Amazonia, whereas, in Borneo and Sumatra, the tropical forest are transformed into palm tree plantations for producing bio-fuels.
Poverty can also be cited as a deforestation cause, but it’s not directly linked to the phenomenon, it’s called an underlying cause. Indeed, poverty make people do a migration near forest frontiers where they’re engaged for slashing and burning forest. Other underlying causes can also be given such as state policies, agricultural subsidies, tax breaks timber concessions and global economics factors. Although, in Africa, Asia and South America, rainforests are considered as home for a huge number of people, local and national governments continue to develop the rainforests exploitation.
Finally, another factor can be named: the access to technology. Indeed, using inefficient technology increases collateral damage in the deforestation’s vicinity, whereas, using new technology urges the forest clearing.

    There are many reasons why a forest would be removed however the biggest issues are industrial growth, agriculture, consumerism and the clearing of land for farm animals. According to the United Nations ' Food and Agriculture Organization “an estimated 18 million acres of forest are lost each year” (Bradford). The methods in which a forest is removed is also harmful to the environment. Some methods include burning and use of heavy equipment. The burning method releases carbon that has been stored in the trees into the atmosphere again contributing to global warming.…

    (Bradford) It is one of most significant, if not the most significant cause of animal endangerment. The destruction of habitats accounts for 36% of the loss of species in the Brazilian Amazon. (“Endangered”) “Forests are complex ecosystems that affect almost every species on the planet. When they are degraded, it can set off a devastating chain of events both locally and around the world.” (Bradford) Deforestation can be traced back to European settlers in the 16th century, where it has developed to become part of the culture. Space is cleared for activities, but the species of wildlife are burned…

    Deforestation is one of the major global issues of the contemporary world. Humans and animals depend on trees for the production of oxygen so that they can breathe, yet universally, world annual deforestation is estimated at 13.7 million hectares a year. The annihilation of such immense quantities of forestland will have devastating consequences in the future, especially considering that fewer trees will result in a smaller intake of carbon dioxide, adding more emissions to the greenhouse effect. Forests cover 31% of our planet’s land, they fulfill many roles such as providing renewable raw materials and energy, maintaining biodiversity, and protecting land and water resources; forests are heavily exploited, but important efforts are being…

    As more people are wanting palm oil for their needs, that means that people needed to find land for mass production. Forests are being chosen and are being stripped away due to the demand of palm oil. This is causing animals and plants to lose their homes. Knohl, a professor in bioclimatology states that changing land from forest to palm oil plantations impacts biodiversity, stored carbon, and warms the earth's surface, which adds to climate change (Deforestation Linked to palm oil Production, 2017, para.3). Deforestation has a domino effect on other factors in the forests.…

    Forests are essential to the Earth as they regulate global warming by absorbing carbon (Cesareo and Walker). Unfortunately, trees can also greatly harm the climate when they are cut or burned down. Struck states that, “As forests die, they release carbon dioxide, further raising Earth’s atmospheric temperatures.” As trees are cut down, the Earth’s climate is rapidly harmed. Deforestation is the second largest man-made contributor to increase in carbon levels of the Earth’s atmosphere and is responsible for about fifteen percent of all global warming (Bradford). The sheer amount of carbon released into the atmosphere is dooming future generations at an immense pace.…

    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.…

    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.…
