Decreasing Areas of Primary Rainforests lead to a ban of illegal logging

Originally rainforests covered around 14% of the earths land surface, today its around 6% only. Thus this heavy loss and the outlook that even more ecologically unique and precious rainforest will be destroyed lead to increased public sensitivity with respect to uncontrolled logging of tropical timber. The consequences of allowing illegal logging of precious woods from natural primary forests are devastating - from an environmental and ecological point of view:
Biodiversity:?Estimated 137 plant, animal and insect species are lost due to deforestation each day. This translates to a loss of 50,000 species a year. The loss in biodiversity impacts the whole ecosystem. Erosion:?Cleared land is more venta de camisetas de futbol baratas likely to be affected by erosions, land-slides and flood. Water-absorbing vegetation is missing as the forest area has been cleared. Contribution to Climate Change:?The loss of trees and their carbon capturing abilities, leads to more carbon being extracted in the atmosphere, thus facilitating climate change. Potential pharmaceuticals:?The rainforest is also a great source for pharmaceuticals and possible cures for illnesses and diseases. Ca. 25% of Western pharmaceuticals are derived from rainforest ingredient but not more than 1% of tropical flora has been researched by scientists. Native tribes:?The destruction of living space leads to the loss of natural living space for native tribes.

Despite humanity is aware of this disastrous ecological consequences, the destruction of forest lands continues in the tropics. The drivers of this process are the following:
Growing population:?Having more people means they will require more space for living, additional infrastructure, facilities, food and products. Prices also normally raise in the city centers, thus especially the poor people are increasingly ousted to the edges of existing settlements. In order to survive, the easiest is to move to more urban (and thus less expensive areas) acquiring additional land through clearing new forest and start cultivating the land for agriculture. This way civilization is slowly growing and consumes more and more of the previous forest areas. Value of timber:?Tropical hardwoods are very valuable and especially the old trees with thick diameters are nearly impossible to produce in today's timber plantations in meaningful time. Thus felling old and thick tropical hardwood trees leads to good money when selling its timber. Also to mention, some logging permits are sold very cheaply due to corruption, thus de facto selling-off the rich natural and green resources of tropical countries at discounted prices. Mining:?The search for precious and industrial metals often ends in remote areas which need to be camiseta manchester city fc accessed by trucks, machineries and other heavy equipment thus normally requiring the clearance of forest area Roads:?New roads are built either for public transport or to easier extract precious woods camiseta fabregas when managing forest properties. As soon as there are roads, new additional facilities are needed to accommodate travelers for food, gasoline and lodging which consumes also additional land.?
