1. In recent years, in order to seek a lot of wealth from nature and make their lives more comfortable, human beings have selfishly cut down forests, reclaimed land with a large number of hailstones, and discharged industrial waste......However, what about the consequences of doing so? The sky is no longer blue, the streams are no longer clear, the forests are no longer dense, and the green hills are no longer green......
Humanity has harmed nature, and nature will punish humanity! If you don't believe it, please see: tsunamis, **, sandstorms are raging all over the world, the climate is warming, the glaciers in Antarctica are gradually melting, the forest area is decreasing sharply, and the land is desertification and ......Humanity has suffered an unprecedented catastrophe!
2. Science and technology are developing, human beings are progressing, from ignorance to knowing, from ignorance to civilization. Thousands of years of wind and thunder, thousands of years of soaring, thousands of years of vicissitudes, thousands of years of glory. However, thousands of years later, the stars have changed, and what is the face of our homeland in front of us?
Who wants to see a bruised earth that wants to cry without tears?
Yes, it is absolutely necessary for human beings to develop and exploit resources and energy for better survival, but all development and utilization should be comprehensively and scientifically considered from the entire natural world, especially the ecosystem of the earth's environment, and then on the basis of protecting the natural environment and maintaining ecological diversity, to achieve harmony between man and nature.
Protecting nature and developing it is the best of both worlds! However, in the current situation, it is not enough for human beings to stop destroying the existing natural resources and protect the natural environment.
On the basis of the existing natural environment, we must restore the original natural features through artificial reconstruction, so as to protect the balance of various elements in the ecosystem, so as to achieve the ultimate goal of protecting the environment!

Environmental protection is to study and prevent the deterioration of the natural environment due to human life, production and construction activities, and then seek to control, govern and eliminate the pollution and damage to the environment by various factors, and strive to improve the environment, beautify the environment, protect the environment, and make it better meet the needs of human life and work.
2. Human beings live in the natural environment, so the natural macro environment is the basic condition for human survival, and it is the material source for the development of production and economic prosperity. Without the vast natural environment of the earth, it would be impossible for human beings to survive and reproduce.

For example, between organisms in the ecosystem, between organisms and the environment, and between environmental factors, there is a constant flow of energy and a cycle of materials; Ecosystems are constantly evolving and evolving:
The biomass changes from less to more, the food chain changes from simple to complex, and the community changes from one type to another. The environment is also in constant flux. Therefore, the ecological balance is not static, but will always be caused by the change of a certain part of the system, causing an imbalance, and then relying on the self-regulation ability of the ecosystem to bring it into a new equilibrium. It is this iterative process from equilibrium to imbalance to establishing a new equilibrium that drives the development and evolution of ecosystems as a whole and its components.
2.Ecological balance is a relative balance rather than an absolute balance, because no ecosystem is isolated, it will have direct or indirect contact with the outside world, and will often be disturbed by the outside world. If the external disturbance or pressure is within the range it can tolerate, it can be restored through self-regulation ability when the disturbance or pressure is removed. If external disturbances or pressures exceed the limits of what it can bear, its ability to self-regulate is undermined, and ecosystems decline or even collapse.
The limit of the pressure that an ecosystem can withstand is often referred to as the "liminal limit", for example, the grassland should have a reasonable livestock carrying capacity, and the grassland will be degraded if the maximum suitable livestock carrying capacity is exceeded; Forests should have a reasonable amount of felling, and if the amount of felling exceeds the amount of growth, it will inevitably cause the decline of the forest; The emission of pollutants must not exceed the self-purification capacity of the environment, otherwise it will cause environmental pollution, endanger the normal life of organisms, and even death.
If the ecosystem is disturbed by the outside world more than it can self-regulate, it will lead to the destruction of the ecological balance. Ecological equilibrium is a relatively stable state of the structure and function of an ecosystem in a certain period of time, with the input and output of matter and energy nearly equal, and can be restored to the original stable state through self-regulation (or artificial control) under external interference. When external disturbances exceed the self-control ability of the ecosystem and cannot be restored to its original state, it is called ecological dysbiosis or the destruction of ecological balance.
The ecological balance is dynamic. Maintaining ecological balance is not just about maintaining its original stable state. Ecosystems can establish a new equilibrium under the beneficial influence of humans, achieving a more rational structure, more efficient functions and better ecological benefits.
Sustainable development.
Since the middle of this century, social, economic and political issues such as resources, environment, and population have become increasingly acute and globalized, and the so-called "human dilemma" has attracted more and more researchers. Among them, the results of the research of the Club of Rome are the most remarkable. Founded in April 1968, the Club of Rome is a small group of renowned scientists, economists and sociologists. >>>More

The influence of the natural environment on the ancient Egyptian civilization was decisive, because under the specific social environment at that time, people's understanding of the natural environment was not comprehensive enough, and they believed that most of the wind, rain, thunder and lightning produced in nature came from their most revered gods, forming a certain mythology.
Describe the natural environment: a thousand miles as far as the eye can see, thousands of mountains and rivers, thousands of rocks and ravines, beautiful mountains and rivers, mountains and rivers, heavy rain, thousands of purples and thousands of reds, dark and dark, colorful, colorful, calm, wind, rain, wind and rain, wind and rain, wind and sunshine, thousands of weather, birds and flowers, red willows, green flowers, green flowers, verdant and dripping, vast oceans, gardens, fertile fields, surging clouds, poor countryside, mountains and mountains, spring and bright, spring and autumn, spring and scenery, spring is cold, spring is warm, spring is full of spring, spring is full of thorns, grass grows, warblers fly Desolate The willows and flowers are bright and the flowers are bright and the flowers are red, the warblers are singing and the swallows are dancing, the wind and the waning moon are pouring rain, the sea is overturned, the smoke is vast, the wind and the rain are bleak, the wind is like the sea of smoke, the vast sea and the sky are the clouds covering the sun, the floating light is shining, the breeze and the moon are colorful, the flowers are falling, the water is clear, the lakes and mountains are inhabited, the thunder and lightning are combined, the number is nine, the cold sky covers the sky and the sun, the sky is boundless, the water is dripping into ice, the flowers are like flowers, and the storm is showy.
