Register to read the introduction… “Soil erosion is, thus, the process by which soil particles are detached from their original site, transported, and eventually deposited at a new location.” (WRI, p. 134) In the case of deforestation, erosion will occur faster than natural erosion. This is called “accelerated erosion”. “It is often 100 times as destructive as geologic erosion.” (WRI, p. 135) In the event of such erosion, the soil becomes useless. It loses many of its nutrients. And, the new deposition can even cause water pollution in nearby lakes, rivers, or oceans.
     Another major problem associated with deforestation is species loss. According to the World Resources Institute (p. 92), “(Deforestation) directly affects species biodiversity by diminishing the amount of natural habitat available, blocking migration routes, providing avenues for invasion by nonnative species, and changing the microclimate along the remaining habitat edge.” It is crucial that this damage is recognized and taken account of.
     To show the effects of deforestation, I have chosen two nations. One nation, New Zealand, is a more developed nation. The other nation, Brazil, is a lesser-developed nation. By studying the data available on these countries, we will be able to see what the impact of deforestation has been on each country through a better understanding of each countries economic status

According to the data in the World Resources Institute, there are 417 known mammal species in Brazil. Of these species, 71 are threatened. There are 751 threatened species of higher plants.
     Another impact that deforestation has on the environment is land degradation. Whether it is the harvesting of trees or clearing the rainforests for cropland or mining, the soil is paying the price of this overuse. This is land that will not be usable due to improper harvesting techniques, which suck the nutrients out of the soil.
     Since Brazil is a developing country, it is first of all necessary for the government officials as well as the public to be educated in the importance of the biodiversity of the rainforests. The people need to have a better understanding of what the forest ecosystems are really providing them. Education is the first
