Deforestation essay introduction

This is no longer required today, but 12 March of every year in China is the Planting Holiday. Also, it has introduced the Green Wall of China project, which aims to halt the expansion of the Gobi desert through the planting of trees. In Western countries, increasing consumer demand for wood products that have been produced and harvested in a sustainable manner is causing forest landowners and forest industries to become increasingly accountable for their forest management and timber harvesting practices.

The charity uses donated money to buy up and preserve rainforest land before the lumber companies can buy it. The Arbor Day Foundation then protects the land from deforestation. This also locks in the way of life of the primitive tribes living on the forest land. Greenpeace in particular has also mapped out the forests that are still intact [] and published this information on the internet. In order to acquire the world's demand for wood, it is suggested that high yielding forest plantations are suitable according to forest writers Botkins and Sedjo.

By contrast, natural forests produce about 1—2 cubic meters per hectare; therefore, 5—10 times more forestland would be required to meet demand. Forester Chad Oliver has suggested a forest mosaic with high-yield forest lands interspersed with conservation land. Globally, planted forests increased from 4. In the country of Senegal, on the western coast of Africa, a movement headed by youths has helped to plant over 6 million mangrove trees.

The trees will protect local villages from storm damages and will provide a habitat for local wildlife. The project started in , and already the Senegalese government has been asked to establish rules and regulations that would protect the new mangrove forests. While demands for agricultural and urban use for the human population cause the preponderance of deforestation, military causes can also intrude. One example of deliberate deforestation played out in the U.

Before the onset of the Cold War , defeated Germany was still considered a potential future threat rather than a potential future ally.

To address this threat, the victorious Allies made attempts to lower German industrial potential , of which forests were deemed [ by whom? Sources in the U. As a consequence of the practice of clear-felling, deforestation resulted which could "be replaced only by long forestry development over perhaps a century". Operations in war can also cause deforestation.

For example, in the Battle of Okinawa , bombardment and other combat operations reduced a lush tropical landscape into "a vast field of mud, lead, decay and maggots". Deforestation can also result from the intentional tactics of military forces. Clearing forest became an element in the Russian Empire's successful conquest of the Caucasus in the midth century.

Deforestation eliminates a great number of species of plants and animals which also often results in an increase in disease. Often the destruction of predatory species can result in an increase in rodent populations which can carry plague. Additionally, erosion can produce pools of stagnant water that are perfect breeding grounds for mosquitos, well known vectors of malaria , yellow fever , nipah virus , and more. Deforestation is occurring all over the world and has been coupled with an increase in the occurrence of disease outbreaks. In Malaysia , thousands of acres of forest have been cleared for pig farms.

What is Deforestation?

This has resulted in an increase in the zoonosis the Nipah virus. Another pathway through which deforestation affects disease is the relocation and dispersion of disease-carrying hosts. This disease emergence pathway can be called " range expansion ", whereby the host's range and thereby the range of pathogens expands to new geographic areas.

Accompanying the reservoir species are pathogens that have the ability to find new hosts in previously unexposed regions. As these pathogens and species come into closer contact with humans, they are infected both directly and indirectly. A catastrophic example of range expansion is the outbreak of Nipah virus in Malaysia. The bats, through proximity spread the Nipah to pigs. While the virus infected the pigs, mortality was much lower than among humans, making the pigs a virulent host leading to the transmission of the virus to humans.

This resulted in reported cases of encephalitis , of which resulted in death. This example provides an important lesson for the impact deforestation can have on human health. Another example of range expansion due to deforestation and other anthropogenic habitat impacts includes the Capybara rodent in Paraguay. A now well-developed theory is that the spread of HIV it is at least partially due deforestation.

Rising populations created a food demand and with deforestation opening up new areas of the forest the hunters harvested a great deal of primate bushmeat, which is believed to be the origin of HIV. From Wikipedia, the free encyclopedia.
