Why is the living environment of human beings on earth getting worse and worse?

Children, for this question, you can ask your parents, what is the difference between the current living environment and when they were children, whether it is better or worse in general, you can also look up the data to see whether the average life expectancy of human beings is increasing or shortening, and then make a conclusion that the living environment of human beings is getting worse and worse. If you are going to complete your homework, say these things to the teacher, and the teacher will not be able to say that you are wrong.

With the growth of human population and the increase in the demand for quality of life, the exploitation of natural resources is increasing, and the impact on the natural environment is also increasing, which does not mean that human beings are doing bad things. If you live in the deep mountains and old forests, there is no water and electricity, and there are jackals, tigers and leopards all around, I am afraid that the living environment will deteriorate. Although it is said that if people do not pay attention to the protection of the environment, the living environment of human beings may deteriorate in the future, but now that more and more people are aware of this problem, the development of science will also reduce the damage to the environment, so there is no need to be so pessimistic.

Pursuing too much materialistic things, many of which are not necessary for life; Ignoring the cultivation of morality and ethics at the spiritual level is just blindly comparing and taking. However, I believe that these problems will be overcome in the future!

Quite simply, because people have too many desires, and the attributes of desires are endless, they will be extremely extravagant, thus destroying the environment and oppressing other parts of people to satisfy desires, in fact, the roots of war, suffering, and hatred are all like this.

Because of the irrational exploitation and utilization of the earth by human beings, the contradiction between human beings and the geographical environment has become more and more intense.

It should be said that in addition to humans, the living environment of other animals and plants is getting worse and worse. Human development consumes natural resources, and damage to the natural environment is inevitable. The deterioration of the natural environment does not mean that the living environment of human beings is getting worse and worse.

This is a description of the living environment, and I hope it will help you.

Because the population is getting bigger and bigger.

Moreover, material development and spiritual development are detached, and several civilizations before mankind have perished in this way.

Behind all this prosperity, there is a huge crisis, science can bring convenience to people, but also bring disasters to mankind: environmental degradation, material mutation, modern diseases, devastating wars.

Don't think that morality is a false thing, but when humanity is generally lost, it is the end of humanity.

Because the population is increasing, the resources required are also increasing, and the awareness of environmental protection is poor, which will naturally destroy the environment on which we live, so it is necessary to maintain ecological balance and sustainable development.

Ecological balance refers to the state of highly adaptation, coordination and unity between organisms and the environment in the ecosystem and between various populations of organisms through energy flow, material circulation and information transmission within a certain period of time. That is to say, when the ecosystem is in equilibrium, the components in the system maintain a certain proportional relationship, the input and output of energy and matter tend to be equal for a long time, the structure and function are in a relatively stable state, and when affected by external interference, it can be restored to the initial stable state through self-regulation. Within the ecosystem, between producers, consumers, decomposers and abiotic environments, a relatively stable state of energy and material input and output dynamics is maintained for a certain period of time.

We all know that the Sun is the star of the solar system, and nearby celestial bodies revolve around it. At the same time, the sun is also a yellow dwarf, it will continue to expand and glow, maybe the sun will become a red giant star in the next billions of years. Maybe we didn't exist by then.

Summary. The first is that the total population of the earth is increasing year by year, making the earth's limited resources more and more inadequate per capita. When human beings explore the various resources of the earth, they are also causing certain pollution and damage to the earth!

Fishing and hunting practices also cause damage to the ecological balance of the earth! If the earth's ecological balance is out of balance, it will affect and harm human beings! Secondly, the chemical pollution caused by human beings in the process of development and progress, and the destruction of the human living environment by wars are all making the earth's environment worse!

The first is that the total population of the ground-based ball is increasing year by year, making the earth's limited resources per capita more and more insufficient. When human beings explore the earth's Tongfeng oak resources, they are also causing a certain amount of pollution and damage to the earth! Fishing and hunting practices also cause damage to the ecological balance of the earth!

If the balance of the earth's ecology is out of balance, it will affect and harm human beings! Secondly, the chemical pollution caused by human beings in the process of development and progress, and the destruction of the human living environment by wars are all making the earth's environment worse!

Can you add, I don't quite understand it.

Factors such as population increase and chemical pollution.

The Earth is speculated to have survived for 4.6 billion years, but how long will it live? Scientists believe that if the Earth is allowed to move freely, it may exist forever, but if other external factors interfere with it, the Earth may have an end of life. The external factor is the sun in the first place, because it is the closest planet to the earth and can have a destiny on the right earth That is to say, all the energy and power on the earth come from the sun, and once the sun has three long and two short, it is bound to affect the earth.

Before the 30s of this century, people always thought that the sun would one day burn out, turn from white to orange and then to red, and finally become a dark star that was silent, but its brilliant life. In the 30s, when physicists learned the mystery of the sun's light, the situation was very different. It turns out that the Sun's energy comes from its thermonuclear reactions, and the Sun's lifetime will pass through the gravitational contraction phase, the main-sequence star phase, the red giant phase, and the compact star phase.

The main sequence phase is the period of stability of the Sun. This phase will last for 10 billion years. At present, the sun is only halfway through and is in middle age.

Once the Sun reaches the red giant stage, then the end of the Earth is coming. Of course, this is billions of years away. Are there any other factors besides the sun's interference with the earth?

Some scientists believe that the Sun may have a brother, a companion star of the Sun, which orbits the Sun day and night, and turns to the closest place to the Sun every 26 million years"Make waves"Its strong gravitational pull will cause a large disturbance of many comets, and 1 billion comets will be on a rampage in the solar system, and the Earth and other planets will become these comets"Target".If the mass of the comet that collides with the Earth is large enough, the consequences are unimaginable: the extinction of light organisms and the upheaval of ecology; Heavy landslides and earth cracks, the earth"Broken bones".

However, this solar companion star, which could bring misfortune to Earth, has not been discovered, although many scientists believe it exists. From which side of space will the Earth be destroyed by a blow from the space? When will the earth die?

However, the length of time human beings can survive on the earth depends on the changes in the earth's environment and whether the resources can sustain human needs.

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.
