摘要：由于人类的破坏，与栖息地的丧失等因素，地球上濒临灭绝生物的比例正在以惊人的速度增长。在工业社会以前，鸟类平均每300年灭绝一种，兽类平均每8000年灭绝一种;但是自从工业社会以来，地球物种灭绝的速度已经超出自然灭绝率的1000倍。因此我们要爱护动物，爱护地球。

Earth can not satisfy the greed of mankind
1998 flood world, in addition to climate anomalies, such as rainfall concentrated natural causes, but also exposed deforestation, soil erosion, a large population,围湖造田and other issues, and I think that is another noteworthy factor fueling science and technology man's greed, and encouraged the people to go for the natural desire.
People yearn for eat well, put on their living is born with good wishes, from the primitive society to the next renewal of the eternal theme. However, when the impact of Western civilization in China, it is found that buses and trains convenience, machine guns and artillery power, lighting, radio and charm. We can refuse to Western Christianity, the refusal of Western democracy and the rule of law, the rejection of Western music and art, we can not resist the material science and technology temptation. Even in the Cultural Revolution,狠批capitalism all the time, people still use electric lighting, radio to communicate with the latest instructions of Mao Zedong, Mao Zedong to inspect various parts of the still train. After the Third Plenary Session of the 11th, China began a modernization process, modern contains multiple meanings, in terms of the vast majority of people, first of all, is to raise living standards, that is still fill穿暖after refrigerator and color TV, a electric fans after they also wanted to air conditioning, a bicycle after they also wanted to cars, part of this increase from the science and technology be able to do this? Economics is a well-known saying: "Supply create demand." Refrigerator, TV, airplanes, computers ... If it were not for scientific and technological inventions, Chinese ancients dream that was never.
Take the most basic conditions for a well-off life energy, an average of the 1940s and the United States on human consumption of energy to be equivalent to 150 slaves, the early 1970s the United States per capita energy consumption reached 400 slaves, machinery instead of manpower . Production and running machines are not the energy, mainly from thermal power, burning coal produces large amounts of carbon dioxide and sulfur oxides, the greenhouse effect and acid rain is the chief culprit, and coal also to the surrounding environment emission from a wastewater and slag. Nevertheless, it is increasingly inseparable from the "energy slaves." Then car as an example, a production of the 1990s the United States needs 1,000 kg steel car, 100 kilograms of plastic, steel and chemicals is not only energy-intensive industries, but also heavily polluting industries, and on the road to automobile emissions. Look at the Yangtze River water quality deteriorating year by year, Panzhihua, Chongqing, Wuhan, Nanjing, Shanghai, the fastest economic development along the Yangtze River five major cities in the Yangtze River pollution has formed a more than 500 km. The well-known American scientist, said: "We celebrate most of the technical achievements - automotive, power stations, on the whole the industry, even modern city itself, from an environmental point of view, are the losers."
United States Vice President Al Gore in the "on the brink of imbalance in the Earth," a book on that the world civilization and the earth's ecosystem conflict with the three most important reason is: population explosion, science and technology revolution, the concept of natural change. In fact, science and technology bear the brunt of this century population explosion was mainly due to the level of medical care, the concept of natural change is due more to provide human use of science and technology, the means to conquer nature. In 1984 it was calculated, in the past 100 years, traffic speed of 102 times, raising 103 times the energy, ability to control the disease increased 102 times, the population growth rate increased 103 times faster than 1,000 years ago communication improved 107 times the acceleration of technology the development, resulting in the accelerated depletion of natural resources, leading to environmental damage and pollution increase. According to 1971 commoner estimates, the United States from 1946 to 1968 among the total pollution level of 200 to 1,000 percent, the same period the population growth levels of 43%, GNP per capita increased by 59%, the latter two are inadequate to illustrate the substantial increase in pollution. He also study the specific commodity growth in synthetic organic chemicals found, wool and paper pulp, electricity, motor vehicles, cement, plastic growing particularly fast, the final conclusion is that technological change is the most important cause of environmental pollution. A historian Toynbee said: "Later, the rapid progress of science, survival from this perspective is useless things. Scientific progress and even very easily lead to human death since."
Master of science and technology in the hands of people. Similarly, the use of science and technology we can reduce pollution, can control the Yangtze River, can be long-term planning of natural resources, and all this because of short-term investment not only benefits, not only to pay returns to make individuals, businesses and local factory sector consciously to protect the living environment is almost impossible. This year there have been frequent leakage of the Yangtze River Levee, piping, landslides, even dyke breach, not the fundamental reason for the backwardness of China's technology level, but do not attach importance to the relevant departments, funding is not in place, the lack of law and public opinion supervision mechanism. On the other hand even if the developed countries of the West to protect the environment than we do better, but there are still holes in the ozone layer, the greenhouse effect, hazardous waste, loss of biodiversity, and so difficult to solve environmental problems. It seems even though there are all kinds of policies and laws, rely on science and technology can only solve some environmental problems.
Meditation flood, I have not cut down a tree on the upper reaches of the Yangtze River, has not been filled in围湖造田in a shovel soil, no water conservancy construction of a corruption penny, but I have no responsibility? At home I have refrigerators, color televisions, washing machines, I go out by the cars, trains and planes, if all 1.2 billion Chinese people, I have a well-off life, what would the natural environment? The Yangtze River Basin industrial and agricultural output value accounts for the country's 40 percent, I am afraid the wealthy on the part of the Yangtze River Basin from ecological destruction and pollution, I buy books and newspapers may be part comes from the Yangtze River basin was felled forests. From the depletion of natural resources, if the world is to achieve the standard of living of Americans, at least 20 Earth.
We embark on a road of no return. No one is willing to abandon its reinforced concrete buildings, he moved back to the grass; nobody willing to give up Electric Company, spent long nights on the bonfire; nobody willing to give up cars, and the legs or riding a donkey赶路. Moreover, the overwhelming majority of people are after would also like to meet a basic better, more technology products, according to the Buddhist view, the people to be empty, and always filled up. All this material enjoyment of the environment should pay the price, an American, said: "We met the enemy, the enemy is ourselves."
We felling virgin forest, we caving in to the Yangtze River sewage, we billowing smoke emissions to the sky, it is the needs of economic development, this is the people's pursuit of material life. When we finally siphoning off the Yellow River, and finally逼疯the Yangtze River, the Huaihe River was dyed black, we are still in pursuit of a single economic growth indicators, the disregard for the survival of future generations of land, rivers, forests and atmosphere, this growth can be maintained how long? If fertile land turned into desert, if full of toxic substances in the air, even if the fish in the rivers are filthy can not survive, then what is the meaning of our life? What is the foundation of our survival? Mahatma Gandhi said: "Earth to meet human needs, but can not satisfy human greed."
