Changes brought about by the development of technology
Technology has brought too many changes to people. For example, the earliest invention of gunpowder enabled humans to split mountains and open roads, build bridges, and build buildings, which promoted the development of various undertakings, and the military industry also developed rapidly; the advent of papermaking and printing technology gave humans the conditions for writing, and promoted people's culture and art. Extensive exchanges of language, technology, economy, etc.; the invention of the compass promoted the development of navigation and trade, completed the geographical discovery, and enabled humans to understand the earth; the current scientific and technological achievements of hybrid rice and super rice have increased food production , solving the problem of feeding the world's population; space shuttles like Shenzhou V, Shenzhou VI... these space shuttles help astronauts land on the moon, explore Mars, and roam in space; artificial satellites provide us with satellite cloud images and weather forecasts, and can also broadcast TV signals; robots can do many things that humans cannot do, such as diving into the deep sea to investigate, and breaking into fires to rescue people; maglev trains are extremely fast, saving time for people to travel; people use atomic energy to generate a lot of electricity...
Human beings have also invented many items that are useful to us, such as telephones, computers, televisions, etc. These items make it convenient for people to do some things. Take the phone, for example: Two people are separated by thousands of miles and thousands of miles, but as long as they pick up the receiver and dial a few numbers, they can hear each other's voice and communicate verbally in just a few minutes. This is the miracle that the phone has brought to mankind. . The phone was not enough, humans invented the computer. The computer is better than the phone. The phone can only hear the other party's voice, but the computer can communicate through text, video conversations, and see the other party. If there is any holiday, send an E-mail and the other party will receive it in a few seconds. This not only saves paper, but also allows others to receive it quickly... The development of science and technology has improved our living standards and quality of life! ”
In the 20th century, humans invented many items that are useful to us, such as telephones, computers, televisions... These items make it very convenient for modern humans to do some things.
Two people are thousands of miles apart, but as long as they pick up the receiver and dial a few numbers, they can hear each other's voice and communicate verbally in just a few minutes. This is the miracle that the telephone has brought to mankind. For more than 100 years, in modern society, it has become an important part of people's work and life. For example, if grandparents are sick, just make a phone call and remind them what medicine they should take. , or just pay attention to something. In the 20th century, it was the telephone that brought us convenience.
Human beings invented the computer. The computer is better than the telephone, and the telephone can only listen. You can hear the other party's voice, and the computer can communicate by text, and you can also make video calls online, and you can see the other party. If there is any holiday, send an e-mail and the other party will receive it in a few seconds, which can save money. Paper can also be received by others quickly.
The development of science and technology in the 20th century has made our human lives more convenient, and technology will continue to develop in the future.
The Scientific Outlook on Development has brought great changes to the ecological environment of Xinjiang
The mountains are evergreen, the water is clear, and the sky is blue. People live in a green home. This is what the people of Xinjiang have dreamed of for generations. Under the guidance of the Party Central Committee with Comrade Hu Jintao as General Secretary, the major strategic thinking of building a socialist harmonious society and adhering to people-oriented and establishing a comprehensive, coordinated and sustainable development concept, the people of Xinjiang are using their own hands to realize this difficult goal for thousands of years. Realizing the dream of a green homeland
Xinjiang is located in the hinterland of the Eurasian continent, far away from the ocean, with scarce precipitation. It has a typical inland arid desert climate, and the desertified land area accounts for nearly half of the total area of the region. , the oasis area only accounts for 4.3%, sandstorm disasters are frequent, and the ecological environment is extremely fragile.
If Xinjiang's economy needs to develop, Xinjiang's ecological environment construction must also develop. How to protect the original environment in the process of economic development. A very fragile ecological environment? Only by fully implementing the people-oriented approach, adhering to the scientific concept of sustainable development, coordinating the relationship between social development and the environment, and achieving a fundamental change in the mode of economic growth can this contradiction be truly resolved.
< p>It is precisely because of the establishment of a scientific outlook on development and the strong support of the Party Central Committee that Xinjiang's ecological construction has entered an unprecedented period of rapid development.In recent years, Xinjiang has vigorously implemented various ecological construction projects. The ecological environment is showing an improvement trend. According to remote sensing monitoring, by the end of 2005, the area covered by vegetation in Xinjiang reached 1.0934 million square kilometers, accounting for 65.96% of the total area of Xinjiang, an increase of 15.8% compared with the third Xinjiang in 2000. The results of desertification and desertification monitoring show that during the "Tenth Five-Year Plan" period, Xinjiang's desertified land decreased by more than 14,000 square kilometers compared with the "Ninth Five-Year Plan" period.
Although this is due to the fact that Xinjiang is in a historical flood period, the decisive role is played by the various ecological construction projects implemented in Xinjiang: afforestation, fencing, ecological management of the Tarim River, etc. The implementation of these projects has resulted in an overall increase in the area of vegetation coverage in Xinjiang.
The most direct effect of increased vegetation coverage is wind protection and sand fixation. Compared with the past, during the "Tenth Five-Year Plan" period, the number of sand and dust weather events in Xinjiang decreased, and the scope and extent of the impact were also smaller.
Today, the pace of ecological construction in Xinjiang has been greatly accelerated. Take the forestry sector for example. The five years during the "Tenth Five-Year Plan" period were the fastest and best five years in the history of forestry development in Xinjiang. The cumulative afforestation area in Xinjiang reached more than 22 million acres, 3.9 times that during the "Ninth Five-Year Plan" period; there were 12 areas in Xinjiang The state, 81 counties and cities have realized farmland forest network, and 93% of farmland has been effectively protected by forest network; natural forest protection project, returning farmland to forest project, "Three North" protective forest system construction project, wildlife protection and natural Key forestry projects such as the construction of protected areas and the construction of fast-growing and high-yield timber forest bases have all achieved rapid development.
Xinjiang’s achievements in ecological construction are reflected in various aspects. Several major root causes affecting Xinjiang's ecology have been effectively controlled: the control of deserts such as the Taklimakan Desert and the Gurbantunggut Desert is increasingly effective; the comprehensive management of the Ta River and the control of Lake Aibi have also achieved remarkable results. At the same time, various places are vigorously renovating their local environments. The environments in cities and villages that are most closely connected with ordinary people's lives have undergone gratifying changes. In recent years, people can clearly feel that there are more trees and birds around, and some birds that have been extinct for many years have returned.
