Why must we care about life (ideology and morality) on earth?

This passage is quite good, please choose some to use.

Since the birth of mankind, clothing, food, shelter, transportation and other production and life have depended on this beautiful planet where we live. The earth's atmosphere, forests, oceans, rivers, lakes, soils, grasslands, all kinds of animals and plants, microorganisms and plankton in the ocean, etc. , constitutes a complex and closely related natural ecosystem, which is also the basic environment for human survival. For a long time, human beings have remained in the conquest and plunder of nature in the process of civilization, and it seems that they have never thought of giving any care and return to the earth that feeds human beings.

1On June 5th, 972, more than 300 delegates from all over the world 1 13 countries gathered in Stockholm, Sweden, to attend the first United Nations conference on human environment. * * * The General Assembly adopted the famous Declaration on the Human Environment, which issued a solemn warning to people all over the world. Predatory exploitation of natural resources, wanton pollution and destruction of the environment will inevitably lead to disasters such as resource shortage, pollution flooding and ecological environment destruction on the earth on which human beings depend. "And called on all governments and people in Qi Xin to work together to protect and improve the human environment, for the benefit of all people and future generations. The meeting reached the following conclusions: the fate of mankind is closely related to the fate of the earth; Environmental pollution has no national boundaries; Maintaining the global environment requires long-term and extensive international cooperation; If the blind and deformed development of human society is not controlled, it will naturally take more cruel revenge on human beings; Protecting the environment means protecting human beings themselves. At the 27th United Nations General Assembly held in the same year, June 5th of each year was designated as "World Environment Day".

In the 20 years since the United Nations Conference on the Human Environment, environment and development have become the new focus of contradictions. Under the circumstance that the global environment is deteriorating and the problem of economic development is very prominent, the United Nations held a world-renowned conference on environment and development in Rio de Janeiro, Brazil from June 65438 to June 0992. More than 65,438+070 delegations from United Nations Member States, 65,438+002 heads of state and government, and representatives of United Nations agencies and international organizations attended the meeting. The Congress adopted the Rio Declaration of Principles on Environment and Development, Agenda 265-438+0 Century and Declaration of Forest Principles, and signed the Framework Convention on Climate Change and the Convention on Biological Diversity. Known as the largest, highest level, largest number of participants, longest preparation time and most far-reaching international conference since the founding of the United Nations, it is also one in human history.

"Rio Environment and Development" and "2 1 Agenda" put forward the establishment of "new global partnership" and "sustainable development strategy", which established the guiding principles and action program for future international cooperation in the field of environment and development. With the joint efforts of developing countries, the meeting agreed to include the main principles that developed countries are responsible for global environmental degradation, provide funds and transfer environmentally friendly technologies on preferential terms in the meeting documents, creating a good situation for international cooperation in the field of environment and development.

However, due to the rapid development of modern industry in the world, the waste gas produced in the production process has seriously damaged the atmospheric ozone layer, threatened the "protective umbrella" of the earth and directly threatened human life and the safety of animals and plants. This is because the ozone molecules in the ozone layer have three oxygen atoms (O3), and the accumulation of ozone forms a thin layer of ozone gas-the ozone layer, which is the armor of the earth, resists the ultraviolet rays emitted by the sun, and basically absorbs all the ultraviolet rays radiated by the sun to the earth's surface, so that the living animals and plants on the earth are protected from being killed by ultraviolet rays, thus being able to reproduce and grow.

However, with the continuous improvement of human industrialization, harmful gases that destroy the ozone layer continue to grow and grow, and the ozone layer that protects the earth begins to show a "yellow card" warning to human beings. For some time, scientists have discovered the ozone hole over the Antarctic, and even over the Arctic, similar problems have appeared. Moreover, it is disturbing that the ozone layer in the whole earth's atmosphere is thinning and the concentration of carbon dioxide is gradually increasing, which makes the global temperature rise obviously.

Ozone is everywhere in the atmosphere, but it is not everywhere. Ozone mainly exists in the bottom stratosphere about 20 to 30 kilometers away from the earth, and its thickness is about 8 kilometers under normal pressure. It can not only swallow a lot of solar ultraviolet radiation, but also limit the temperature of the atmosphere.

Once the ozone layer is destroyed, a large number of ultraviolet rays will March in, directly endangering human beings and other creatures on earth. The culprit in destroying the ozone layer is not nature itself, but ourselves. Many research results have proved that the "culprit" of destroying the ozone layer is chlorofluorocarbons (CFCs) released into the atmosphere in modern human production and life. It is an organic compound containing carbon, chlorine, fluorine and other elements, and CFCs are used in refrigerators, air conditioners, cars, computers, fire extinguishers and so on. When it enters the atmosphere, under strong ultraviolet radiation, its molecules will crack to generate free chlorine atoms. Chlorine atom is very active. With its participation, 1 ozone molecule and 1 oxygen atom can become two oxygen molecules. A chlorine molecule can destroy about 654.38+ million ozone molecules, and its life span is as long as 75 to 654.38+000 years. In this way, the ozone layer will become thinner and eventually there will be holes, thus losing the function of protecting the earth. This preparation has been used all over the world for 60 years and is still in use.

Some western countries explicitly prohibit the use of freon in refrigerants and seek new substitutes. In China, new materials and technologies that can realize refrigeration without using freon, such as "green" products of fluorine-free refrigerators, are becoming more and more popular, and ozone layer protection has also achieved certain results.

The thinning of the ozone layer and the emergence of holes over Antarctica have aroused people's anxiety all over the world because of their terrible consequences. At present, scientific research has confirmed that the depletion of the ozone layer has brought many harms to human beings, the most prominent point is that it has caused an increase in the amount of ultraviolet radiation from the sun on the earth's surface, endangering human and biological lives. For example, the number of people suffering from skin cancer will double, fish in the ocean will die in large numbers, and other animals and plants will also be damaged; Secondly, it causes low-level warming and high-level cooling, which leads to global climate and atmospheric circulation disorder and imbalance between cold and heat. According to the data, the average temperature of the earth in 1990 is the highest since meteorological records. In China, the average temperature in Beijing 1992 reached-1. 1℃, the highest since the meteorological records began in 152.

During the period of 1997, the global temperature generally rose, and the heat wave constantly hit Eurasia.

1August, 1998, the continuous high temperature weather ravaged the middle and lower reaches of the Yangtze River in China, hovering around 36 degrees every day, especially in Shanghai, where the continuous high temperature weather of 38 degrees lasted for a week.

The total amount of greenhouse gases emitted by Japanese factories accounts for half of the total amount of exhaust gas emitted by Asian industrial systems. The so-called greenhouse effect means that in the atmosphere around the earth, besides nitrogen and oxygen, there are carbon dioxide, chlorofluorocarbons, water vapor and so on. These gases are similar to glass. When sunlight radiates to the earth at various wavelengths, ozone in the stratosphere absorbs a lot of ultraviolet light and infrared light in solar radiation, and only visible light can reach the ground. But carbon dioxide has one characteristic: it can let visible light pass almost completely, but it can strongly absorb some infrared light. In this way, the carbon dioxide in the near-surface atmosphere is like the glass and plastic film in the greenhouse, and the sunlight will shine into the surface greenhouse very smoothly, and it is difficult to scatter it again. This will make the earth's surface temperature rise continuously, thus changing the global equilibrium temperature and triggering a series of disasters.

Researchers believe that if carbon dioxide enters the atmosphere at the current rate, the average temperature of the earth will rise by 1.02℃ to 3.36℃ by the end of 2 1 century. Climate warming will lead to the thermal expansion of seawater and the melting of polar glaciers, which will lead to the rise of ocean water level. The disastrous consequences are quite serious, and some coastal cities, such as new york, Shanghai, Bangkok and low-lying Bengal and Holland, will be turned into Wang Yang. In addition, climate warming will cause drought, desertification and hurricanes in some areas, make some areas rainy and waterlogged, and lead to crop failure or crop failure in agricultural production. And this will form a vicious circle, further aggravating the destructiveness of the greenhouse effect.

With the continuous destruction of the ozone layer and the increasing concentration of carbon dioxide in the atmosphere, human beings and all living things on earth are losing their "protective umbrellas" step by step. Such a grim reality has been placed in front of mankind.

Although human beings have understood the warnings of environmental problems such as the thinning of ozone layer, air pollution, waste of water resources, marine poisoning, farmland destruction, sharp decline of animal and plant species, and sandstorms, there are still many factors threatening human peace and survival at any time.

Although human beings are repenting and thinking: we only have one earth, but the future of human beings depends on our choices today.

Is human confession a confession that destroys the earth's environment? I think the environment of the earth has been greatly damaged because of human activities. Moreover, the environment of the earth should belong to space, and human repentance should be to admit that they have destroyed the living environment. Is man thinking about how to prolong the life of the earth? Or how can we not destroy the life of the earth excessively? I feel that human beings have not thought about it at this level, that is to say, how many years will it take to destroy the natural ecological environment of the earth? Or how much will the thinning of the ozone layer damage the age of the earth? Even if the ozone layer is completely destroyed, what about life on earth? So far, the scientist has not been found to have done this research. Humans don't even have this idea at all, just studying that holes in the ozone layer will endanger the lives of humans, animals and plants; The uncontrolled production and lifestyle of human beings is the chief culprit in destroying the ozone layer. Humans even fantasize that once the earth can no longer survive, they will move into space or move to other planets to live. I think it is difficult and unrealistic, because there are too many humans, and it is too difficult to transport so many people out. It can be said that it is impossible, unrealistic and wishful thinking. If the harm of ozone layer to human beings has reached the point where it is necessary to move, I estimate that human beings will be extinct by then.

Only by taking practical and effective measures to protect the earth can we better protect ourselves and make better use of other planets. If mankind can live in peace, stop the war and use the material and human resources consumed in the war to improve the ecological environment of the earth, I believe that the future of mankind will be even better. On the contrary, if human activities keep bad habits, the war will be endless and escalating; Predatory exploitation of resources and uncontrolled production of toxic and harmful gases will further aggravate the vicious circle of the earth's ecological environment, and mankind will gradually approach the danger of extinction. However, if mankind really goes extinct, it does not mean that the earth will perish. The extinction of human beings is likely to be an opportunity for the earth to regain its vitality, just like the germs in the human body are driven out of the body.

The destruction of the earth's ecological environment by human beings seems to have nothing to do with life on earth; It seems that human beings have nothing to do with the life of the earth by plundering and squandering the fossil energy stored on the earth. So what did humans destroy the earth? What is the real meaning of human repentance and thinking? What is saving mankind and saving the earth? The future of mankind depends on what we do today.

Look at today's humans, wearing colorful clothes. There are sweaters, shorts and cool skirts in summer, and leather clothes, down pants and winter clothes in winter. Eating delicacies, big fish and big meat; Living in a high-rise building with heating, air conditioning and gorgeous ornaments; In and out of planes, ships, cars, motorcycles, etc. Which one has nothing to do with the energy of the earth? Is this consumption too much, even a little extravagant? However, these diverse energy consumption structures are closely related to the energy materials stored in the earth, and every link of human production and life is harmful to the ecological environment of the earth. Such as garbage in life, smoke and dust in industrial production, automobile exhaust, war damage, and a lot of pollution. , has not been effectively controlled, but has been upgraded and intensified.

In the process of human civilization, the proudest thing is that human beings constantly develop clean energy such as solar energy, hydro energy, wind energy and tidal energy on the earth into electric energy, which greatly relieves the demand for using fossil energy, reduces the emission of toxic and harmful substances and gases generated by using fossil energy, and makes great contributions to improving human ecological environment. This is the most obvious sign of the progress of human civilization. However, for the earth, its kinetic energy also has a certain role. Water can create vast plains, kill animals and plants, and accumulate their remains. The role of wind energy cannot be underestimated. It sends the water evaporated from the ocean to the distant land, so that there will be rain, rivers and lakes, various biological groups and intelligent human beings on the land, and the earth will become more colorful. Wind energy can also create many hills and plateaus and change the face of the earth. Many people think that the Loess Plateau in China is the result of wind. It turns out that the loess here is native to Central Asia, the Mongolian Plateau and some inland areas in the northwest, where the climate is dry and the rocks on the ground are constantly broken into particles with different thicknesses under weathering. Every time it encounters windy weather, it often rolls up dust and covers the sky, leaving coarse gravel in place and becoming Gobi; Coarse sand is blown by the wind to sink nearby, forming a vast desert that is constantly moving; However, the fine silt moves southward with the wind. When the wind weakened or encountered obstacles such as Qinling Mountains, they fell down one after another. After millions of years of continuous accumulation and environmental changes, the Loess Plateau gradually formed. Although the utilization rate of these clean energy sources is very low, with the exhaustion of fossil energy sources approaching, clean energy sources will surely become one of the main energy sources of mankind.

Perhaps human beings and the earth are the products of two contradictions, which are interdependent and mutually restrictive, that is, the causal relationship of unity of opposites. This explanation speaks for itself. In fact, human beings are not so noble, but a species that lives and breeds in the embrace of the earth. We have no right and should not destroy the earth on which we live-our mother. Because we humans only have one earth.

According to the survey, some major minerals on the earth will be mined in hundreds of years. With the increase of human demand, especially the increase of energy demand, energy shortage will soon appear. The life of fossil energy "coal" stored in the earth is about 200 years; The "life" of oil is only 30 years, although with the improvement of exploration technology, its life may increase to 50 years; Although natural gas reserves are large, with the sharp increase in demand, its "life" is estimated to be slightly longer than that of oil. Therefore, the fate of fossil energy consumption is inevitable and irreversible. For human beings, new energy can be found, but for Mother Earth, will she have other changes because of the lack of fossil energy? It's time for mankind to draw a conclusion about this.
