"I want to reserve a ticket bounds for Indonesia from Korea" is the phrase that shows incredible development of human society. It comes no surprise for most of people that human activities made the earth better place to live as to convenience, efficiency and comfortableness. However, the development has inherent shortcomings; devastation of environment which outweighs benefits of the improvement. People's activities made earth inhabitable place since they divested environments and decreased diversity of species.
Human activates seriously provoked irreversible damage to nature. For their own sake, people overexploited resources of nature. They cut trees, exploited fossil fuels and carried out various industrial activities, emitting harmful gases and polluting water. The worst results of those will be a phenomenon: global warming. According to UN's report, the earth could not go back to its original state unless every country stops development of industries and environments. Moreover, many scientists in the U.S declared that global warming will not be solved until '3000', and this phenomenon will cause various problems such as drought, shortage of water. Therefore, I believe human activities caused problems rather than benefits to the earth.
What takes the cake is human activities decreased diversity of species. Because of development of environment, habitats for various animals and plants have been disappeared. Thus, they have no choices but to fade away from the earth. For example, according to Korean time’s research, activities of factories have increased to 50 percent since 1995. However, correspondingly, the whole sorts of species have been declined to 30 percent. Tigers, native rabbits, dears and a lot of plants have been disappeared. Moreover, because of extreme exploitation of nature in Amazon and other forests, roughly one or two species are being endangered or extinct. By taking those examples into account, I believe human activities made the earth more inhabitable place.
In conclusion, I firmly believe human activities led the earth to be a problematic and unsustainable place to live. People should keep one thought in mind, we should think of next generations. |
