Ours is an age of complexity, contradiction and challenge. At the beginning of the 21st century, although we have the technology unmatched in human experience, it is said that humanity has made little real progress over the past century. Admittedly, scientific technological advances have produced tremendous improvement in the quality of human life. However, they also have negative consequences as well. Nevertheless, this is not a time for despair but for a global commitment to make possible the technology to add the problem of our age.


Admittedly, technology has improved our life dramatically over the past century. With the invention of steam engine in the 19th century, the internal combustion engine in the century just ended, we human beings find ourselves able to exploit on a massive scale energy once locked in coal, oil and gas. At the same time, (dramatic gains in agricultural productivity made possible by) agriculture gained dramatic development by the new technology of water use, fertile and mechanized farming .A large number of people move from farms to cities and factories. The net result is a tremendous elevation of living standard which the world has never seen or even imagined possible. The space travel, miracle drugs, as well as computer technology used in the working place and at home all contribute to our better living standards.


On the other hand, (The increasing complexity of technology also led a new kind of catastrophe, as we see how technology has helped to pollute the environment, lead to the wars, add population pressure and fill the world with goods of questionable necessity.)it is also as clear as daylight that technology has detrimental influence on our life. The risk of cancer caused by the environmental pollution, the possibility of large-scale industrial accidents, the ethical problems drawn by the life-prolong technologies, and the...
