Although extinction and impact events are natural phenomena, we must find a way to prevent an impact on Earth by small and large objects such as asteroids and comets. 【101】If a car approached as you crossed the street, would you rush ahead, return to the sidewalk, or stand in front of it and wait for the collision？ Are we going to wait for an impact from space, or are we going to take steps to avoid such a disaster？ If the future of Earth is to involve the future of society, we should not wait.
【102】Most people do not like too much change, nor do they like to consider altering natural processes. While society has gradually shown a willingness to manipulate human biology to prevent disease, most people are reluctant to consider the possibilities offered by the controversial subject of cloning. 【103】In a similar vein, society seems to believe that it must accept earthquakes as natural and unavoidable, but there are already methods under consideration to avoid as natural phenomena are to deal with, society must not maintain a parochial attitude toward preventing catastrophes that science may help avoid. Now is the time to change our world, to realize that while bad things can and do happen, we may be able to prevent them or at least ameliorate their effects without harming society or our environment. The threat of an impact from space has been considered, and methods to deal with this threat are being discussed. 【104】At the same time, we need to be aware that venturing into space may provide the ultimate answer to whether into space may provide the ultimate answer to whether or not humans can survive another threat, the evolution of our sun. I hope that we are able to develop a willingness to consider new approaches to our environmental and biological problems.
Clearly, science and society are intricately entwined, and as one progresses, so does the other. Pure science, the search for knowledge without knowing where it will lead, is part and parcel of what will make the world a better place for all mankind. The more we learn, the more questions we can ask and the more answers we can obtain. 【105】But as society struggles to find answers to its problems, it would do well to remember that science has touched upon and improved almost every aspect of our lives.We must therefore conquer our fears so that we can continue to progress on all fronts, and explore space as a new frontier that belongs to all of us.

Unconsciously, we all carry with us【51】have been called "body bubbles". These bubbles are like invisible wails【52】define our personal space. The amount of space changes【53】on the interpersonal relationship. For example, we are usually more comfortable standing closer to family members than to【54】. Personality【55】determines the size of this space. Introverts often prefer to interact with others at a greater distance than【56】.
Cultural styles are important too. A Japanese【57】and employee usually stand farther apart while talking than their American counterparts. Latin Americans and Arabs tend to【58】closer together than Americans when talking.
For Americans,【59】in social conversation is about an arm's length to four feet. Less space in the American culture may be associated【60】greater intimacy or aggressive behavior. The common practice of saying "Excuse me," or "Pardon me" for the slightest accidental touching of another person reveals an American attitude about personal space. Thus when a person's "space" is intruded【61】by someone, he or【62】may feel【63】and react defensively. In cultures【64】close physical contact is acceptable and desirable, Americans may be Perceived【65】cold and distant.
Culture does not always【66】the messages that our body movements【67】Contexts, personalities, and relationships also influence them. Therefore, no two people in any one society have the same nonverbal behavior.

As a romantic teenager, I believed that my future life as a scientist would be justified if I could discover a single new fact and add a brick to the bright temple of human knowledge. The conviction was noble enough; the metaphor was simply silly. Yet that metaphor still governs the attitude of many scientists toward their subject.
72.In the conventional model of scientific "progress ", we begin in superstitious ignorance and move toward final truth by the successive accumulation of facts. In this smug perspective, the history of science contains little more than anecdotal interest--for it can only chronicle past errors and credit the bricklayers for discerning glimpses of final truth. It is as transparent a.s an old-fashioned melodrama: truth (as we perceive it today) is the only arbiter and the world of past scientists is divided into good guys who were right and bad guys who were wrong.
Historians of science have utterly discredited this model during the past decade. Science is not a heartless pursuit of objective information. It is a creative activity, its geniuses acting more as artists than as information processors. Changes in theory are not simply the derivative results of new discoveries but the work of creative imagination influenced by contemporary social and political forces. We should not judge the past through anachronistic spectacles of our own convictions--designating as heroes the scientists whom we judge to be right by criteria that had nothing to do with their own concerns. We are simply foolish if we call Anaximander (sixth century B. C.) an evolutionist because, in advocating a primary role for water among the four elements, he held that life first inhabited the sea; yet most textbooks so credit him.(71)

Like the population explosion, the scientific and technological revolution began to pick up speed slowly during the eighteenth century. And this ongoing revolution has also suddenly accelerated exponentially. For example, it is now an axiom in n/any fields of science that more new and important discoveries have taken place in the last ten years than in the entire previous history of science. While no single discovery has had the kind of effect on our relationship to the earth that nuclear weapons have had on our relationship to warfare, it is nevertheless tree that taken together, they have completely transformed our cumulative ability to exploit the earth for sustenance——making the consequences of unrestrained exploitation every bit as unthinkable as the consequences of unrestrained nuclear war.
