Mr. Gujahi
Biodiversity or biological diversity expresses the combination of all living organisms existing on this planet. Nowadays, this topic plays a great role in the world because depredation to all the environments is leading to the extirpation and extinction of many inhabitants of those settings (Grolier Multimedia Encyclopedia, 2009). There are many ways humans have benefited the environment by their actions but in reality, there are more behaviours where humans have negatively impacted our planet. One of these off-putting impacts is clear-cutting. It is defined as the removal of all trees in a generally specified area (NRDC, 2000). How does clear-cutting affect the environment? What species and populations has clear-cutting affected? What are the risks and benefits of clear-cutting?
When you clear-cut a given area of trees, you are virtually cutting down every single tree, leaving a wasteland with no chance of shady areas (Nova Scotia Public Lands Coalition, 2006). Although clear-cutting looks a lot easier and faster to perform than any other method of forestry, companies take advantage of this and abuse it. The overuse of clear-cutting leads to soil erosion and loss of habitats for many species (New Book of Popular Science, 2009). Clear-cutting also means the destruction of buffer zones. Buffer zones reduce the chances of having floods because these buffer zones absorb and hold water (NRDC, 2000).
Many organisms are affected by clear-cutting. In all of the rainforest ecosystems around the world, when trees are clear-cut, the forest canopy is eliminated. Because of this, rainforest insects and bacteria no longer have their habitats, which can endanger them if they do not have a great adaptability (NRDC, 2000). Rainforest organisms make up for about half of the animal and plant species on the Earth so, even though it may not be apparent, clear-cutting these...
