Causes and Consequences of Rainforest Destruction
As the world's population gets bigger and richer, the demand for meat is increasing. To rear the cattle increasing tracts of the rainforest are being cleared to make pastures for grazing
): Hardwoods like mahogany and teak that take hundreds of years to grow are still in high demand to make things like furniture. The extraction of these trees can kills trees around them. Also many countries like China are also demanding large amounts of normal timber that are not always taken from sustainable sources
: Hunting takes two forms, one form is for bushmeat to feed families and enough the sale of animals either alive e.g. parrots or dead for their skins e.g jaguars
: Building new roads like Trans Amazon highway from Brazil to Bolivia not only causes deforestation itself, but its also opens up new ares to urbanisation, mining and farming causing further deforestation
Loss of indigenous homes
: By clearing rainforests, the homes of indigenous groups are destroyed over time. However, moving closer to indigenous groups can easily spread disease and change local culture and traditions.
As populations continue to increase in countries such as Peru, Brazil, India, and Vietnam which comprise of rainforests, the demand for land increases to grow for food as well as to live.
As the world population continues to increase and the level of urbanization increasing as well, the majority of cities such as Manuas in Brazil are growing at an increased rate, amplifying deforestation
: the loss of habitat means the loss of species; this leads to less species in the rain forest which leads to less biodiversity
: as there are less trees, that also means there are less leaves performing photosynthesis, increasing the amount of CO2 in the atmosphere
: as there is less water being taken up because there are less plants, less transpiration occurs
: after deforestation, the soil loses its quality really quickly, so less vegetation grows leading to desertification
: when there are less trees in an area, the rain reaches the ground quicker as there is less interception of the rainfall. Furthermore, less trees means less roots to take the water in the soil.
More Wind/Soil Erosion
: as there is a less vegetation cover, more soil particles are vulnerable to strong winds. these strong winds come from the reduction in trees.
Increased Chance of Landslides
: less trees and vegetation means that the soil is less stable
: The cutting down of trees at an increased rate is motivated by other factors, however, it's the main cause for most of the problems found there
