Through modern technology such as TV, telephone, and the Internet, it has become easier for people from different cultures to communicate. In a sense the world has become a smaller place. However, it is questionable if technology is creating a single world culture, because, even though a cultural exchange is taking place, accessibility of this technology is still very limited, and, more importantly, people have come to value the differences inherent in their cultures.
People around the world are taking advantage of the opportunities, presented by modern technology, to learn about other cultures. Not only foreign movies, music, and books communicate with the locals, but the different cultural values do, which are readily available on DVD, CD and via the Internet. Similarly, TV broadcasts fashions across the world and a new style of dress will likely catch on quickly in different parts of the globe. People adopt foreign things they like and make them their own. In this sense cultural assimilation is taking place.
However, while some societies and their cultures are technologically advanced and thus connected with other parts of the world, the majority of the world's population lives largely isolated. Such isolation is the result of limited technological resources, which in turn is, generally, related to poverty. For example, nearly the entire continent of Africa is impoverished. Its people have few means to learn about other cultures, and even if they did they would have little use for Western culture, which to a great extent is a consumer culture. They are also extremely limited in the ways they can educate people from other parts of the world about their cultures.
Finally, people who are learning about foreign cultures generally come to appreciate and accept the differences between other cultures and their own. They recognize the value of variety. The enjoyment they derive from experiencing foreign languages, dances, songs, visual and culinary arts, also allows them to see the value in their own cultures' achievements. Therefore, cultural exchange does not necessarily result in the melting of many cultures into one.
Science and technology have been bringing human beings tremendous benefits. Thanks to science and technology, we now live comfortably and conveniently in houses furnished with air conditioners, refrigerators, washing machines and televisions etc. Thanks to science and technology, we can eat fresh vegetables at the year round. Thanks to science and technology, we can travel long distances in the fraction of a second on planes, trains and cars. Thanks to science and technology, we wear clothes with synthetic materials which can not easily be worn out.
However, science and technology have atso brought us a lot of disasters. First, because of the many breakthroughs in the field of medicine, people are now living much longer than they used to. As a result, the population of the world is increasing, causing lots of problems. Second, because of the development of industry, lots of the wastes from factories pour into the air and rivers, causing pollution of all kinds. Third, some terrorists are using science and technology against mankind. They use biological, chemical and unclear weapons to threaten world peace...
So it's urgent that we find ways to solve these problems. But we should not stop the development of science and technology because of these disasters they bring, just as we should not give up eating for fear of choking. In addition, we should make some rules to regulate our actions. As long as we use science and technology in a proper way, they may bring us even more benefits.
The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions.
Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before.
Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel.
Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable.
However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce.
Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.
