Invasive species are species that has been introduced to an environment where they are not from originally, and that have since become a problem through spread and increase in population, often hurting the plants and animals already there. Cervus elaphus (C. elaphus), also known as the red deer or elk, is an invasive animal found now all over South America and New Zealand (Flueck, 2010). Originally from North America, Asia, and Europe (hence the common name European Red Deer), Cervus elaphus were introduced less than one hundred years ago in Argentina and places in New Zealand and ran ramped over National Parks and natural forests. They influenced native flora and fauna and disrupt their processes (Flueck, 2010). These red deer cause less regeneration of favored plants which stop normal vegetation to grow thus changing structure and composition of the ecosystem in which they reside (Flueck, 2010).
Also, the deforestation rate has increased in other ways, such as obtain more land for living and excessive uses of wood. Therefore, a large amount of trees were cut down and led to forest destruction. People have done these kinds of activities for many years and these deforestation activities have brought a lot of permanent and long term issues. Although the society has started to consider the problem of deforestation, it is not easy to solve the issues completely. The land desertification can be a huge area and it is almost cannot be able to control.
The Detrimental Effects of Deforestation Deforestation has been around for many years. Before America was discovered, fuelwood was the main source of energy, so many trees were being cut down all over Europe to provide energy for the inhabitants. Even still today, 2000 million people in low income countries still rely on wood for cooking and heating (Causes, 1). The rate at which we are loosing our world’s forests is steadily increasing. During the 1980’s, worldwide deforestation rates were at 15 million hectares per year for tropical forests alone (WRM, 1).

It is obvious that our expansion has affected many other living creatures in the ecosystems of many areas around the world. Many may have thought that a large population is difficult for governments to support. Little that we know, in the process of sustaining our growing population, we’ve devastated the environment and put many of its living creatures at risks. If we don’t change and solve the problem on overpopulation, then in a few decades, I suspect, the Earth wouldn’t be such a nice habitation like it is now and generations after us would have to suffer from the consequences that we’ve made.
The poaching of listed and endangered animals along with maintaining the current rate of trafficking of animal products is causing drastic environmental effects, as well as, the extinction of many animals, and the problem is only said to increase within the coming decades. Poaching, the illegal practice of trespassing to hunt or steal game, has become a worldwide trend in which criminal syndicates have taken part in. Countries that have a high poaching rate include the United States and Africa, but the animal parts taken from these countries are traded all over the world. There are many reasons why poaching has been proven unnecessary over the years, yet the killing of rhinos and elephants for their horns and ivory has increased by over 300 percent since 1989. (Odula 2) Many people who are not as obviously impacted by these changes question as to why this is relevant and how it pertains to their wellbeing.

An Industry on the Brink: Consumers Need to Wake Up and Smell the Genetically Modified Coffee A recent upsurge of opposition to the production of genetically modified crops has farmers all over America asking themselves one question: To modify or not to modify? Genetically modified (GM) crops allow farmers to use fewer pesticides while still achieving the same yields. American farmers have planted GM crops since 1995 and, at least for the first few years, had no problems selling these products to the public. Recently, however, there has been a movement by several activist groups, some of which have the support of accredited scientists, to make a distinction on grocery store shelves between GM foods and those that were produced normally. This process, called labeling, strikes fear in the hearts of most farmers who are afraid that an uninformed American public will steer clear of the GM crops “just to be on the safe side.” The fact of the matter is that Americans have been eating these altered crops since 1995 and no one has been harmed.
