We humans are living to consume the earth s resources?

Man is a product of nature, but human development takes place in the destruction of nature. The Earth was born about 4.5 billion years ago, and life on Earth occurred about 3.5 billion years ago. The emergence of human beings is only 3 million years old.

The only recorded civilization of mankind is 6,000 years old. In the long history of human development 300 years ago, human beings and nature were basically able to live in harmony. However, in the 300 years since the Industrial Revolution, human plundering and destruction of nature has approached the limit of nature's support for human life.

According to the current scale of exploitation, oil and gas can be consumed for a maximum of 50 years, and coal can be consumed for a maximum of 100 years; By 2020, most of the earth's mineral resources, including copper, aluminum, tin, zinc, gold, silver, etc., will be mined. Today, the environmental and ecological crisis is on full display: the hole in the Antarctic ozone layer is expanding; The global climate is changing, and the greenhouse effect is causing the sea level to rise; Air pollution, marine and freshwater pollution, soil pollution, and chemical pollution caused by industrial production are quite serious; The forest coverage rate has been greatly reduced, and the desertification and desertification of land have become increasingly serious. Human disease rates are rising, species extinctions are accelerating, and so on.

In short, the earth's resources are declining sharply, the ecological environment is deteriorating, and the conditions for redevelopment and sustainable development are constantly being lost in the rapid development of human beings centered on materials.

Solar energy is definitely the trend, although the utilization rate is very low, but the amount is very large, and with the progress of science and technology, the utilization rate of solar energy will gradually increase. Nuclear power is dangerous and too high-tech, so progress should be slower. As for wind energy, it is now found that wind power has an effect on atmospheric convection or something, and it will cause harm to birds, and it may gradually slow down the development, or only develop this energy source in a local area, and tidal energy and geothermal energy are limited by geography and cannot be popularized.

Although hydropower is relatively clean, it also has many drawbacks, so I won't talk about it here, so the cleanest and most guaranteed is solar energy.

As for the international transport industry, oil transportation is only one part of it, and oil alone will not have a fatal impact on it. Companies transporting oil can switch to other goods.

There is no standard answer to this question, and different research institutions and personnel have different arguments, and in general, they can be divided into two categories: optimists and pessimists. Many of the pessimists are already known to have the idea that there are only enough oil reserves for another 50 years, and that when the oil reserves are depleted in 50 years, humanity will face a crisis. Optimists first say that there is no need to worry about this, and that when a certain resource is depleted, human beings will develop new alternative resources.

What's more, now a new theory has emerged, which believes that oil is not formed by the deposition of ancient animal remains, but is a substance of the earth itself, and its storage capacity is far greater than the current amount, and it can be exploited for a long time. In addition, the melting of glaciers caused by the greenhouse effect has long been thought to bring unprecedented disasters to mankind, but now that the glaciers in the Arctic Ocean continue to melt, it seems that there is no human concern for disasters, and the countries concerned are busy competing for a new waterway formed by the melting of glaciers in the Arctic Ocean.

Therefore, on the one hand, human beings should have a sense of distress, and must not be unscrupulous and do whatever they want in the face of nature, but must exercise restraint and take precautions. On the other hand, there is no need to be too pessimistic and worrying, and we should learn to turn the crisis as an opportunity to find a new way out when the crisis comes.

Brothers this year 2020, mining is finished.

It has only been less than 100 years since oil was discovered and used Now oil extraction has reached its peak Now the global oil extraction is already declining Do you think it will be enough for 100 years from now Hehe So it will be a terrible thing not to find alternative resources in 100 years The above is purely a personal non-professional opinion!

I wish that day would come soon!

1. Specific problems should be analyzed in detail. Resources are divided into renewable resources and non-renewable resources.

2. Renewable resources such as bioenergy and water energy will not be exhausted.

3. Non-renewable resources will be depleted if other factors are not considered. For example, it has always been said that oil, gas, coal, etc. will run out in a few decades.

However, human society is constantly developing, and science and technology are making rapid progress.

1. On the one hand, the proven reserves of non-renewable resources such as oil are increasing.

2. On the other hand, the efficiency of human use is constantly improving, for example, the original incandescent lamps are tens of watts, and now the 5-watt LED lamps can achieve the effect of the original dozens of watts, so as to achieve energy saving.

3. The emergence of new alternative energy sources, from coal to oil to natural gas to shale oil and shale gas, from fossil energy to clean energy, is moving towards the path of sustainable development.

4. Human consciousness is constantly improving, and we know about environmental protection and energy saving.

Therefore, we should be optimistic about the planet and our society so that the resources available to us will not be exhausted.

According to the principle of conservation of energy, the earth's resources will not be exhausted! According to the current knowledge and technology, it cannot be recycled, but the energy is used all at once. In fact, it is the change of matter from one to another, and the substance itself does not decrease or increase.

For example, in the use of water. By pouring water into the ground, crops grow, synthesizing new energy sources for us to eat or make into other things.

But the water did not really disappear, but was converted into water vapor and floated in the air, and finally returned to the earth in the form of precipitation. Petrochemicals are actually converted into other substances in different ways of use. Humans don't yet have the technology to resynthesize matter in a reverse way.

If we consume only the energy generated on the earth now, we will run out of energy one day.

Theoretically, it will be depleted, but non-renewable resources will be consumed faster, and renewable resources can be recycled until the earth is destroyed as long as human beings protect them.

Resources in a broad sense are inexhaustible, and when a resource is exhausted, alternative resources will emerge, or society will revert to the social form it wants to adapt to.

Theoretically, according to the formula e=mcc, the energy is not used up. As for materials, there are also new alternative materials.

If it's the environmental aspect, it's really worrying.

In fact, it will not be depleted, it will only be continuously reduced, and then it will reach a zero point, because at the same time as it is consumed, other resources are also generated.

Depending on the situation, the renewable ones will not be renewable, and the non-renewable ones will be depleted.

Forest resources.

The Earth's forests were once 7.6 billion hectares, but now they are less than 36 hectares. Over-deforestation and deforestation are reducing the world's forest area by almost 1 per cent every year.

Freshwater resources. The world's water consumption is now 10 times higher than it was 100 years ago. About 60 per cent of the world is water-scarce, and about 1.5 billion people in 80 countries face water shortages, of which about 300 million people in 26 countries live entirely in water scarcity.

Mineral resources. Mineral resources are limited, and now the rate of mining is accelerating, so that some minerals are in short supply and even facing depletion.

At that time, humanity will remain in this desolate land forever. (unless people develop new energy sources).

Is it possible to move to other planets when the earth's resources are depleted?

It's almost impossible, first of all, Mercury is too hot, the moon has no atmosphere (of course, you can dig a hole in the ground where there is water near the poles), Mars is more similar to Earth, but scientists are still desperately looking for water on it, and it is too far away, the composition of the atmosphere is not good, and the transportation cost is very problematic. The winds howl on the surface of Jupiter every day, and those small moons can also be considered. If you are a little farther away from the sun, it will be too cold.

Anyway, with the existing space transportation technology of mankind, it will not be possible to go anywhere. The nearest planet outside the solar system, Proxima Centauri, is also four light-years away, and the average spacecraft would take 400,000 years!

Depending on what resources are, some resources will and some will not. For example, coal, natural gas, and oil will run out, and various metals and quartz can be recycled.

As the saying goes, born in sorrow, died in peace, anyway, there has always been a sense of sorrow, for the future of mankind, many people imagine this, as the earth's resources continue to be consumed one day will be consumed, no resources can not survive, so we must find a new place to live, and the exploration spacecraft sent by scientists has been working hard to develop in this direction.

In many sci-fi movies, we can see that the population of the earth has far exceeded its carrying capacity, so many people will choose to live on other planets, which can reduce the pressure on the earth and help the earth recover.

Yes, in a few billion years, the earth will be gone, and in 5 billion years, the sun will disappear.

Leaving the grass on the plain, one year old and one withered. Wildfires burn inexhaustibly, and spring breezes blow and regenerate.

In millions of years, resources will eventually run out. But the vicissitudes of life, the earth without human beings will slowly return to its natural state, and no one is inseparable from anyone, only time and space.

A: The fact that the earth's resources should be depleted.

Renewable resources are theoretically inexhaustible, non-renewable resources will!

According to reports such as USGEOLOGICALSURVEY and Worlsenergyreport, about the next 20 to 30 years, the remaining reserves of industrial metals will face a shortage, and in the next few hundred years, non-renewable resources such as oil and mineral deposits will also face a shortage. If we humans do not pay attention to the protection of these resources, or abuse the resources, we will face crises such as resource shortage, climate warming, ozone layer depletion, and air pollution, and our living environment will be severely challenged.

For the sustainable development of resources, people have thought of many ways to save resources: such as sorting garbage and extracting reusable materials, carrying out protective development of non-renewable resources, improving resource development technology, improving resource utilization, and intervening in the excessive development and utilization ......of resources by legal and other means, etcWhile there are many ways to do this, they still don't solve the problem of increasingly scarce resources. Therefore, only by relying on scientific and technological progress, developing alternative resources, and gradually getting rid of dependence on traditional resources is the trend of sustainable development of resources in the future.

As a result, biofuels, nuclear energy, hydropower, solar energy, wind energy and other energy uses have gradually emerged, among which solar energy is the most representative of the future of renewable energy development. Because solar energy is not like other renewable energy sources, it is limited by various conditions such as geography, technology, and environment, and solar energy can be continuously used wherever there is sunlight. Therefore, countries around the world are paying more and more attention to actively promoting the development and popularization of solar energy to cope with the shortage of resources in the future.

With the continuous progress of human science and technology, if there are no irresistible factors. Human survival is not a problem.

The 5 billion years I'm talking about upstairs just refer to the current consumption of resources by human beings.

But, I said it. Humanity is constantly improving. The world is slowly starting to pay attention to sustainable development. The use of resources will become more and more restrictive.

As long as the level of human civilization continues to improve according to the current development, I think, whether it is energy or biological resources. Humanity will be able to find a better way than it is now. to control resources. Rational use of resources.

But. 5 billion years is indeed a great difficulty for mankind. In 5 billion years, the sun will run out of its own nuclear raw materials.

Slowly transformed into a red giant, at this time. The Earth will no longer exist. Of course.

If 5 billion years of time. Humans have established settlements on other planets. That would have avoided this catastrophe.

But. That's not something we're thinking about.

All right. It seems to be off topic. Not much.

My opinion is. How long the resource lasts. It's just a matter of how humans use it. Because the laws of physics: the laws of conservation of energy and mass tell us. Resources don't disappear. It's just something else. If we could recycle it.

The resource is depleted as follows:

1. In recent years, in order to seek a lot of wealth from nature and to make their lives more comfortable, human beings have selfishly cut down forests, reclaimed a large amount of land, and discharged industrial garbage ......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 of Antarctica are gradually melting, the forest area is drastically reduced, and the land is desertified in large quantities ......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!
