Land is the foundation of human existence, so which land in the world is the most barren and unsuita

There are a large number of human beings living on the earth, because the speed of human reproduction is very fast, so most places on the earth are inhabited by humans, and human beings are constantly developing new living space, but there are still some places where there are few people, but they are not suitable for human habitation. For example, some high mountains, Antarctic, Arctic, and some desert areas are not suitable for human existence.

1. Antarctica.

Antarctica is frozen all year round, and the temperature here is very low, with some scholars measuring the lowest temperature of -89 degrees Celsius.

It is very difficult for human beings to accept this temperature, and when the temperature in the north of our country reaches minus 40 degrees, it is already too cold, let alone minus 89 degrees! And the annual precipitation in Antarctica.

It is also very low, often accompanied by windy weather, so the temperature will be even lower, and this place is not suitable for human life at all, even animals are rarely able to adapt to the climate here.

2. Sahara Desert.

After talking about the coldest region above, we will go to another extreme region, which is perennially arid and is the largest desert in the world, with a total area of 9 million square kilometers.

It's about the same size as China, but there aren't many people living here, there's no way to grow plants, there's no good resources, the climate is dry and hot, and the overall living conditions are very bad! The most important thing is that there is no water source here, and there is no way for human beings to live without water, so this place is also very unsuitable for human survival, even if you want to pass by here, you must carry enough water, otherwise you will not be able to pass here!

3. Amazon.

Amazon rainforest.

Compared with the above two places, it is relatively rich in resources and materials, there are many animals and plants, but here is the perennial rainfall is very large, and the rainy season is very long, the air is very humid, the most important thing is that there are too many animals and plants here, and there are many poisonous animals.

I think the most barren land in the world is the Dead Sea, it's so salinity that no living thing can survive, let alone humans, it's the least suitable place for human life.

Antarctica, the land of this place is not suitable for human survival, there is no way to grow plants, and it is the most unsuitable place.

The desert land in the world is the most unsuitable for human life. Because this kind of land cannot grow plants, people living in this place will also lack a lot of water, and it is difficult to survive.

Problem Family Destruction Description:

There are a lot of soilless cultivation techniques now, so do you still need land?

Analysis: There are several reasons why human beings need earth to survive

1. From the perspective of qualitative preparation, human beings are terrestrial animals, and land is a necessary condition for survival.

2. From the perspective of ecology, a complete ecological environment needs land.

3. From the perspective of crop cultivation, most crops still need to be cultivated with soil.

Human selfishness, human beings' open and secret fighting, global warming, oil tension, the hole in the ozone layer, all these things remind mankind all the time that the earth provides a good living environment for human beings, but human beings are so ignorant that there is only one earth, and human beings continue to survive But do you really want to see the earth become a water ball?

Experiments have shown that the United States has built a regenerative and confined ecosystem"Biosphere 2"。However, a year later, the experiment was declared a failure.

This means that the earth is our only home.

Earth Sharp Manpower provides a large amount of apprentice forest, water, and air.

1.The Earth and the Sun are neither too close nor too far away, guaranteeing the formation of liquid water.

2.The Sun is an "isolated" star in the Milky Way galaxy whose motion is less affected by other stars.

3.There is a Jupiter near Earth that is much more massive than Earth, making it more likely that an asteroid in the universe will crash into Jupiter than Earth.

All of this makes it possible for life to exist on Earth.

Soil is an important foundation for human survival, and soil provides a habitat for human beings - home.

Soil is the mother of plants, providing nutrients and water for plants, and soil also provides a habitat for animals. It is the common home of our humans, animals and plants. It is precisely because of the soil that there is this beautiful and lovely world, so we need to protect the soil.

1) Generally speaking, cultivated land is mostly distributed in flat plains, low hills and basins in the eastern monsoon region, dry fields in the northern region, and paddy fields in the southern region, mainly planting crops. Woodlands are mostly distributed in mountainous areas with more precipitation, and are rich in timber and fruits. The grassland is mostly distributed in the northwest inland area, with developed animal husbandry and abundant livestock products.

Most of the cities are construction land, and the hard-to-use land is mostly distributed in the Gobi, desert, high mountains, stone mountains and other places. (Answer according to the specific situation) (2) Due to the rational use of materials and the increase of population, problems such as soil erosion, land desertification, and indiscriminate occupation of cultivated land often occur. (Answer according to the specific situation) (3) Generally speaking, the development potential of land resources in the eastern monsoon region is small; In the northeast, northwest and other remote areas, there is relatively much undeveloped land, but the soil is poor and the climatic conditions are poor.

Answer according to the specific situation) (4) In line with the principle of using land resources according to local conditions, we should not only make full use of them, but also protect the ecological balance. (Answer on a case-by-case basis).

The earth is altruistic, and it generously provides mineral resources to humanity. However, these resources cannot be regenerated, and if they are not exploited in a controlled manner, the mineral resources on the earth will inevitably become less and less, and they will be mined for another two or three hundred years at most. Omitted below).

Reading this, I want to say: "Humanity, there is only one earth in the world, and if she is destroyed, we have nowhere else to go." If all the resources on the planet are depleted, it will be difficult for us to replenish them from elsewhere.

We must carefully protect the earth, protect the earth's ecological environment, and make the earth better for our future generations. ”

In Chinese teaching, there is a practice of turning this sentence into a sick sentence for students to learn to identify and revise

Replace "generously" with "endlessly", the whole sentence will not make sense, it will become a sick sentence, since "endlessly", why is there less and less? There is a lot of energy that can be used to describe it, but that is not earthly. ^_

The earth is (altruistic) and it provides mineral resources to human beings, but if they are not exploited in moderation, there will be fewer and fewer resources on the planet.
