Tragedy of Deforestation

Human activity can negatively impact on the environment in different ways, which can lead to consequences which are not only bad for the environmental area affected, but humans too. Activities such as causing radiation leaks with nuclear meltdowns and dumping waste are just some examples of how humans can worsen their own environment.

One environment damaging human activity in particular is deforestation. It is a significant problem in many parts of the world, with over four fifths of the worlds forest wiped out according to the World Resources Institute. So what are the main consequences which are caused by deforestation, and why does it happen?

A major result on the environment is the habitat destruction and endangerment of animals. Rainforests contain over half of the world’s plant and animal species, while making up 7 percent of the Earths land mass. They reside in ecosystems which have developed for hundreds of millions of years. Some species only live in certain microhabitats, making them ultra prone to quick extinction. When their habitat gets destroyed, entire animal populations can be wiped out from certain areas, although occasionally leaving portions of populations behind. Even then, the surviving pockets may suffer from decreased biodiversity or isolation from other pockets of the remaining population. This could disrupt the imperative food web in many ways, such as higher order consumers no longer finding prey or an inadequate amount of producers. The lack of abundance of one level of the food web would likely create a ‘shockwave’ effect causing problems through the food web. The canopy layer of a forest is vital to block out sunlight and retain heat, so its removal causes fluctuating temperatures which can be dange...
