deforestation and BiodiversityWhile the loss of forests is clearly visible, a decline in biodiversity has a less app atomic number 18nt effect. The subtle loss of biodiversity fails to indicate the significance that few species in the ecosystem increases the fragility of life for all species. Despite the negative personal effects of deforestation and the consequential decline of biodiversity, trees are cut down for an sparing and consumer benefit. Members of society need to determine how much economic cost they are willing to spend in order to preserve plant and animal(prenominal) species.To reduce the degree of deforestation, tree harvesters may use selective logging, which involves solely the removal of trees that are the most economically beneficial. steers with lower economic pry are left standing. This method still has problems intrinsic with any liberal of deforestation and selective logging also introduces new environmental problems. Tree harvesters need to build roads into the forests to remove the timber (Vandermeer and Perfecto, 1995). The road locution means that a greater surface of land will be covered by asphalt, which increases the amount of rainwater runoff that is not filtered by the soil before entering a stream. These streams are polluted by sediment carried by the rainwater.Vandermeer and Perfecto also say that selective logging introduces auxiliary damage when non-targeted trees are knocked down in the process of removing the desirable trees. In addition, selective logging over a long period of quantify leads to deterioration of the stand, which reduces the overall value of the forest when the loss of more semiprecious trees leaves lower grade timber behind (Vandermeer and Perfecto, 1995).Another change colligate to the effect of sel... ...eforestation/deforestation_3.html.Sanchez-Azofeifa, G., Rivard, B., Calvo, J., Moorthy, I.
