2 1 century is an inter-generational century, and 2 1 century is destined to be a high-tech era, which inherits the great scientific and technological invention-steam engine and promotes the development of the whole industrial revolution. The telephone has opened a new chapter in the history of human communication; Cars carry the progress of the times; Television, modern people can eat and drink for a day, but they cannot live without it for a day; Landing on the moon is a big step in the history of human space; Computers, the hope of the future of mankind, and so on. The pace of human progress has never stopped. The development of science and technology is still the theme of this century. The development of science and technology has brought me various conveniences. However, while we are happy, we should also think carefully about how much we have paid for it. High-tech and Natural Environment Since the invention of the steam engine, human society has embarked on a stage of rapid development. Today, all kinds of industrial high technologies make it impossible for human beings to leave them. They are the foundation of social development. However, while pursuing excessive development, should we notice that our earth is becoming more and more fragile? The Copenhagen World Climate Conference was held in Copenhagen, Denmark. The significance of this meeting lies in arousing people's attention to the natural environment. Science and technology have greatly improved their ability to control nature and themselves. However, the problems encountered in the application of science and technology to society are becoming more and more prominent. The development of industry has brought water and air pollution, and large-scale reclamation and overgrazing have caused ecological damage to forests and grasslands. Over-reliance on high-tech production, advanced logging machines, advanced, the global climate is becoming more and more impermanent, desertification is serious, the melting speed of ice in the polar regions is accelerating, the sea level is rising, and the annual average temperature is getting higher and higher. This shows that our high technology has brought us a high degree of civilization, but also made nature out of balance. As the most advanced animal, human beings have been fighting against nature since ancient times. Did man conquer nature or did nature retaliate against man with bad weather? Many high-quality talents in economy and management often talk about win-win and win-win wisdom. When can we achieve the so-called win-win situation between man and nature? We should protect the environment. Everyone cares about the environment, and now the environment around us has been seriously damaged. The lesson that human beings failed to protect the environment has actually existed since ancient times. In ancient times, Mesopotamia, Greece, Asia Minor and other relatively developed areas became barren due to unreasonable reclamation and irrigation. The Yellow River Basin is the birthplace of ancient civilization in China. Due to deforestation, floods and droughts frequently occur. The land is becoming more and more barren. The consciousness of protecting the environment is not new now. In ancient China, there was a simple idea to protect the natural environment, that is, "catch an inexhaustible river and hunt without burning the forest". Today, we should not only protect the environment from pollution, but also inherit the ancient idea of environmental protection, rationally utilize resources and ensure the sustainable utilization of resources. You know, the key to solving environmental problems is to protect the environment. Protecting the environment means protecting ourselves. In the high-tech and humanities fields, there is such a thing: a pair of parents play online games and take care of a virtual baby, but let their children starve to death. It really happened in Korea. People who have been with computers for a long time are not in normal contact with the society and live in the virtual society of the network. Coupled with the influence of computer radiation and noise mentioned above every day, over time, it is easy to lead to mental illness. Psychologists recently found out in the outpatient clinic that people who often deal with computers will unconsciously become serious and indifferent people because they are faced with a lifeless computer screen for a long time, which will affect their daily interpersonal communication, thus creating psychological and spiritual obstacles. Television, computer and internet bring us a lot of things, but they don't give us time to think, such as online games, TV series, stealing vegetables and so on. In fact, the Internet is a double-edged sword, depending on how we use it. Some people are addicted to the virtual world and forget to play games, which wastes a lot of youth, which is regrettable. Without self-control and self-control, they will eventually taste Russia. However, some people will make good use of the inexhaustible resources of the Internet to serve their work and study. High-tech communication technology has made the earth "smaller", and the cultures of all countries in the world are constantly merging, but China people are increasingly worshipping foreign things. For example, the popular nouns in recent years, such as Ha Han and Ha Ri, and the popularity of western festivals in recent years, are all manifestations of worshipping foreign things and flattering foreign countries. Nowadays, young people like "foreign festivals" more and more. Christmas is a carnival, April Fool's Day is a lie, and Valentine's Day is a romance. Everything is so enjoyable that it has even gone up. Roses are sold all over the street, as if everyone has a so-called "lover" As a result, some people lament that the world is going from bad to worse, as if "the country will not become a country." Many people talk endlessly every day that we have a culture of five thousand years, but how many people have inherited it? How many excellent ones have you inherited? High-tech and economic development Scientific and technological progress has promoted transportation and strengthened global economic integration. Only by increasing investment in education and science and technology, using advanced science and technology to develop production and taking the road of rejuvenating the country through science and education can the whole economic development be invincible in the increasingly fierce international competition. The global financial crisis that broke out a few years ago greatly affected the Asian economy. The world economy has been severely shaken. Reflecting on the lessons of the Southeast Asian financial crisis, it is recognized that one of the important reasons is that the scientific and technological foundation of economic development is not solid enough and the ability of independent innovation is not strong, which leads to the lack of competitiveness of the domestic economy under the trend of economic globalization and it is difficult to resist huge economic risks. Science and technology are the powerful driving force and solid foundation for economic development. This has been verified by historical facts. In the coming 2 1 century, the role of scientific and technological progress in economic development will be further strengthened. 2 1 century will be the century in which knowledge economy will dominate. The ability and efficiency of creating and applying knowledge will become a decisive factor affecting a country's comprehensive national strength and international competitiveness. The future of mankind and the prosperity of the country depend more on the development of science and technology than ever before. Scientific and technological progress is the basis of economic restructuring. The development of science and technology has promoted the optimization and upgrading of industrial structure. It also has a great impact on the mode of production and people's lives, especially new products with high technology content and great market potential, which have a strong guiding role in the adjustment of industrial structure. Therefore, the driving force of economic restructuring lies in science and technology, and the hope lies in science and technology. Through scientific and technological progress, strengthen agriculture, transform and upgrade traditional industries, develop emerging industries and high-tech industries, and improve industrial technology. Forming a reasonable scale and structure, accelerating the pace of industrial structure optimization and upgrading, improving the scientific and technological content of products and enhancing the market competitiveness of products are the basis for promoting industrial structure optimization and upgrading. The development of science and technology has greatly changed our lives. Modern science and technology is a double-edged sword. I believe that in a hundred years, the level of human scientific and technological development will be unimaginable to all of us here, just like the humans who drilled fires in the Stone Age. They can't imagine there is gas and electricity in our world now. Only time can tell us what the ultimate fate of mankind will be.
