What are the least suitable environments for human survival?

Plateaus above 6,000 meters, seabeds below 300 meters, underground below 3,000 meters, deserts with annual precipitation of less than 50 ml, etc. There are many places on the earth that are not suitable for human life, and the total land area of the world is 100 million square kilometers.

Only 80 million square kilometers are available for human habitation.

The number of human beings has reached 7 billion, and it is difficult to feed so many people by simply hunting from nature, but fortunately, human ancestors.

Domesticated some animals and plants to grow food crops.

and feeding and grazing, which is able to provide enough food for humans. But correspondingly, the fields suitable for the development of agricultural production are also affected by the natural environment.

In the mountains of more than 5,000 years, most crops are difficult to survive, the natural environment is not conducive to human development, and the relative population is very small.

Human city-state.

It is much less difficult to build a city in a low-altitude plain, and it is possible to do a good job in overall planning and building design and connectivity between other cities. However, in the plateau, the tundra is not suitable for building large cities, the cost of building cities under the sea is too high, the forests need to be protected and cannot be cut down on a large scale, and the urban drinking water and green water supply in the desert is a problem, and the cost is high.

Whereas, humans are social animals, and few people really rely on themselves, are self-sufficient and do not communicate with the outside world. There is not only the influence of the geographical environment, but also the influence of the spiritual and social aspects, and it can be said that except for the population gathering area, other places are not suitable for human survival. The environment is suitable, the living is convenient, the life is stable, and it is very good to live in **.

The natural environment in the countryside is certainly much better than that in the cities, but the working and living environment can never catch up with the cities, so it is impossible for the city people to rush to the countryside again, and even if there is, it is only a small number of people.

The environment is the basic condition for our survival, so we must protect the earth on which we human beings depend. Caring for the environment is everyone's responsibility.

For example; Desert, the majority of the desert area on the earth, such as the Taklamakan Desert in China, after the transformation of our forest protection project, the desert has also become a tourist mecca, but there is an extreme desert generation on the earth, which is not suitable for human survival and transformation, that is, Ethiopia, which is the hottest and driest region on the earth, but the Arabs survive in this environment. Moreover, the Kamchatka volcanic group located in Russia, the volcanic dense part, perennial volcanic eruptions, tortuous landforms, not suitable for the survival of any animals and plants, also known as the 'Valley of Death', and the almost environmental location, Indonesia's Sinabon Volcano, this volcanic group is basically in a state of continuous eruption, causing great harm to the inhabitants of the place, as well as Snake Island in Brazil, the forest town in Australia, etc., are all nightmares for human beings, although humans are the most intelligent primates, but in front of nature, It also seems so small, so it is important to protect the environment and the home of our common human existence.

Mount Everest, the North and South Poles, the equator, the deep seabed, and the desert are all unsuitable for human life, because these environments are very harsh, either too cold, or too hot, and some are thin air, which is not suitable for human survival.

Located in Russia, the Kamchatka volcanic group, the volcanic dense part, perennial volcanic eruptions, tortuous terrain, not suitable for the survival of any animals and plants, and the almost environmental location, Indonesia's Sinabung Volcano, this volcanic group is basically in a state of continuous eruption, causing great harm to the residents of the area.

The way humans survive in four extreme environmental conditions.

The environment in which human beings live is divided into the natural environment, the social environment, and the economic environment.

1. Natural environment.

The natural environment refers to the combination of natural elements such as climate, soil, water, air quality, vegetation cover, etc., on the earth. Humans depend on the resources of the natural environment and the ecosystem services it provides, such as food, water and climate regulation. The technological environment includes a variety of scientific discoveries, innovations, and technological applications, such as information technology, medical technology, and industrial technology.

2. Social environment.

The social environment includes social systems, culture, social relations, and social values. It covers political, economic, educational, legal, religious, moral, and other factors that have an impact on the behavior and lifestyle of individuals and groups.

3. Economic environment.

The economic environment involves the distribution, production and consumption of resources, including money, markets, employment, etc. It affects people's income, consumption levels, and opportunities for economic development. The technological environment refers to the impact of the development and application of science and technology on human society.

Multi-dimensional development direction:

1. Survival and development.

The human living environment is a multi-dimensional concept that encompasses many different aspects. In addition to the above-mentioned natural environment, social environment, economic environment, etc., there are other factors that also have an important impact on the survival and development of human beings.

2. Sustainable environment.

Sustainable development of the environment refers to the harmony and balance between human life and development and the environment. It involves the rational use of resources, the protection of the environment, and the stability of ecosystems. The construction of a sustainable environment is to ensure that the needs of modern society are met without damaging the ecological environment, leaving a sustainable earth for future generations.

3. Coordinated development of various environmental elements.

The various aspects of the human environment are intertwined and mutually influential, and together constitute the foundation of the development of human society. Paying attention to and improving the living environment of human beings and promoting the coordinated development of various environmental elements is an important task for achieving sustainable and all-round development of human beings.

At the same time, it is also necessary for people to work together to promote progress in the fields of environmental protection, education, health care, and safety through the actions of the people, organizations, and individuals, so as to create a better living environment and provide more stable and sustainable development for the future of mankind.

There are three reasons: First, there is water on the earth, and water is the basis for the existence of life.

2. The temperature on Earth is suitable for life.

3. There is air on the earth, and air is also the basic element on which life depends.

The human living environment includes ().

a.Natural.

b.Social environment.

c.The political environment is talkative.

d.Economic search environment.

e.Community. Correct answer: ab

Global warming: The consequences of global warming will redistribute global precipitation, melt glaciers and permafrost, and rise in sea levels, which will not only endanger the balance of natural ecosystems, but also threaten human food** and living environment.

Ozone layer depletion: In the stratosphere, about 20 30 kilometres below the surface, there is an ozone layer in which ozone levels account for 1/100,000 of the total gases at this altitude. Although the ozone content is very small, it has a strong function of absorbing ultraviolet rays, so it can block the damage of the sun's ultraviolet radiation to the earth's organisms and protect all life on the earth.

However, some pollutants emitted by human production and life, such as hydrochlorofluorocarbons (HCFCs) in refrigerators and air conditioners and other uses of fluorobromide compounds and other uses, can be exacerbated by ultraviolet irradiation to form highly active atoms and ozone (O3) of the ozone layer, making it become oxygen molecules (O2), which occurs in chains, and ozone is rapidly depleted, so that the ozone layer is destroyed.

Acid rain: Acid rain is acidic precipitation with a pH less than that caused by acidic pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) in the air. In areas affected by acid rain, a series of serious environmental problems have occurred, such as acidification of soils and lakes, destruction of vegetation and ecosystems, and corrosion of building materials, metal structures and cultural relics.

Freshwater crisis: Although the Earth's surface is covered by water23, 97% of the Earth's surface is undrinkable seawater, and less than 3% is freshwater, of which 2% is sequestered in polar glaciers. Of the only 1% of freshwater, 25% is used for industry and 70% for agriculture, with only a small fraction available for drinking and other domestic purposes.

However, in such a water-scarce world, water is abused, wasted and polluted.

Resource and energy shortages: At present, the problem of resource and energy shortage in the world has occurred in most countries and even on a global scale. The emergence of this phenomenon is mainly caused by unplanned and unreasonable large-scale exploitation by human beings.

First of all, of course, the desert area is not suitable for human habitation, because the desert area is short of water and the yellow sand is flying all over the sky, which is extremely unsuitable for human habitation, and the second is the Antarctic and Arctic regions, and the climate of the Antarctic and Arctic regions is extremely cold all year round, and it is not suitable for human habitation.

There's the Danakil Desert in Ethiopia, which is very hot and there are volcanic lava rocks nearby. There is also Fukushima, Japan, which has strong radiation because of the nuclear leak. It is still uninhabited.

1. The Antarctic continent is low temperature and drought with strong winds all year round.

2. Sahara Desert A large area is covered by desert, and the climate is hot, dry and water-deficient.

3. Siberia Winters are long and cold, and most areas are not suitable for farming.

4. Amazon Tropical Rainforest: The rainy season is long, the rainfall is large, the humidity is high, and there are many poisonous insects, and the large area of the rainforest is not suitable for human activities.

5. The Qinghai-Tibet Plateau has thin air, low oxygen content, and an arid climate.

There are many places in the world that are not suitable for habitation, such as the North and South poles, the equator, and the desert. The north and south poles are too cold to survive, and the equator is too hot for human survival and development.

The living environment of human beings is composed of the natural environment, the artificial environment and the social environment.

The natural environment refers to the living space including climatic conditions, geographical conditions, and ecosystems associated with animals and plants.

Artificial environment refers to the living environment formed by artificial processing, including residential design and support, public service facilities, transportation, water supply, gas supply, green area, etc.

The environment in which human beings live is determined by temperature, air, water, gravity (determined by the mass of the earth), and sunlight (the solar spectrum is just right).

What is the environment in which humans live? First of all, air, water. And the food.

There are two main parts: the environment and microorganisms.
