TOPIC: ISSUE121 - "At various times in the geological past, many species have become extinct as a result of natural, rather than human, processes. Thus, there is no justification for society to make extraordinary efforts, especially at a great cost in money and jobs, to save endangered species."
WORDS: 572 TIME: 00:45:00 DATE: 2007-9-6 18:11:18
"The sixth Great Extinction is comming," experts in ecology and geology says, "The past five great extinctions have shaken the earth. We, human being, is the course of the comming great extinction." Thus I fundamentally disagree with the author's assertion that It is not our responsibility to make efforts to save endangered specis merely because we believe many species have become extinct as a result of natural processes rather than human activities.
Admittedly, lots of species extincted in the past Great Extinction because of natural reasons during the past four billions years. The paradigmatic example is the extinction of denasours, which have been living on the Earth for two billions years, and was extincted in around 1.5 billions ago. It is said a small planet hit the Earth at that time, and the detail reason, some experts belive, is because the number of female danasours is much bigger than the male denasours. Therefore it is safe to say that the extinction in the ocient is caused by natural force, while the current condition is far different from that time.
According to the statistcs of proffessor , there are nearly 100 species dispearing from the world in every single day. And he predicated, one forth to half or the species will become extinct till 2050.
Though lots of these extinction we can easily contributed to the natural process, we can find the human's contributation when we make a further observation. The human activity accelerate the process of precies extinction, though sometimes its effect is indirect. The simple example, in the document of experts, a road, we build in the areas where the wild species living, can affect the life of butterflies day life because they cannot go to the opposite as they usually do. Thus they were sepate in each part, and the lack of communication make them another life and another results. The such kind of road's influence on the bigger animals such as lion and tigger will be even obvious.
Experts found lots of the so called natural extinction is closely related to the global warming, which resulted from the industralization due to the great development in technology. The temperature is higher than what they can bear. Though we can say some of those can survive are pririous than those extincted, and the extinction of the latter can be belived to be the result of natural process, it is the human who indirectly caused the death of these species which must can live on the Earth a little longer.
We have reduced or ceased our action to hunt the wild animals, but our works are still threaten their very existence. And this will in turn threaten the existence of human in this planet. We surely will pay for what we have done if we don't realize our responisbility--merely shift our responsibility to the nature process, and the disastrous consequence of these species today will be the tommarrow of human beings'.
In sum, to realize the problem is the first step to solve the problem. Some measure should be taken to reserve the endangered species, and try to spark a delicate balance between development and environmental protection which , can creat a idea living condition for these species,is the most effective way to save these endangered species. Ony by so, can we live harmoniously with them.
Every corner of the world has been left feetprint as the human come to this world.
