According to Haider Rizvi (2007), “We are living beyond the means and capacities of our planet.” The Earth is being damaged badly daily. Humans are destroying their unique shelter. A rapid increase in the human population and an increase in the standard of living have resulted in widespread damage of the environment. People are destroying habitats and reducing the amount of land available for other organisms by building, quarrying, farming and dumping waste. The more society develops, the more modern technology develops, the more innocent animals will suffer. Therefore, people have to change their ways immediately or they are all going to die. To make it work, they should be aware of the environmental damage and take action to prevent further consequences in nature. Some of those serious problems, for example, natural disasters through deforestation, all the species of plants and animals disappear, and humans will eventually vanish. The human exploitation of natural resources also brings about the damages in nature, such as global warming and greenhouse effect. Then, they lead to animal extinction, plant loss, and the disappearance of the habitat of many species. As a result, the rapid exhaustion of the Earth’s natural resources becomes the most important issue nowadays that will cause many consequences in nature. In a word, some of those bad effects that human activities cause to nature are change in climate, species extinction, and marine ecosystem damage.
Human activities are considered to be contributing to an increase in average global temperature (Shah, 2012). First, human activities in general release carbon dioxide into the atmosphere. This seems not to be a problem because people think that plants will absorb carbon dioxide and produce oxygen to clean the atmosphere as “a carbon cycle”. However, the problem here is that people are exhausting far beyond the capacity of the environment. The amount of carbon dioxide they exert to the atmosphere “goes beyond the plants’ ability to absorb”. Therefore, it makes carbon dioxide stored up in the air. This is the reason that causes global warming because the heat that the Earth absorbs from the sun can’t escape back into space. Also, it brings about the green house effect and the temperature increases (Tietenberg, 1994). Moreover, people continue rising the amount of carbon dioxide in the atmosphere while they keep cutting down the trees and destroying many forests. It is accepted that to develop, people need more space to serve their needs. For example, they need soil to build cities and roads; in addition, because the increasing population requires for more food, they are now ranching and farming over the forests which are destroyed to attend to agriculture. However, it does not mean to abuse it. Forests are the only source which helps to restore the air. Nevertheless, humans do not consider the consiquences of their actions. When the forests do not exist any longer, what source will provide oxygen? Destroying forests also means destroying human beings. Climate changes resulted in the greenhouse effect and global warming that both have a strong effect on human life and biodiversity. “Long term changes in average temperatures can dramatically alter the habitats that provide life support for plants and animal species” (Rizvi, 2007). The rise in temperature leads to the change of the environment which is the living habitats of animals and plants. Obviously, animals live in the poles where ice melted change their habitat. Any animals which can’t adapt quickly with these changes will lose and disappear (Schneider and Root, 2002). Species extinction
Species extinction is an important issue today because there is a huge amount of species that have disappeared due to human activities. In the article “Rain forest – Species Extinction”, it claims that, “Some scientists estimate that as many as 137...
