First of all, from the perspective of our clothing, food, housing and transportation, brightly colored clothing needs to be chemically treated and dyed, and colorful synthetic fibers are a major contribution to chemistry. One of the keys to filling grain bags and enriching vegetable baskets is to develop the production of chemical fertilizers and pesticides. The processing and manufacture of food with good color and flavor are inseparable from various food additives, such as sweeteners, preservatives, spices, flavorings and pigments, etc., most of which are extracted from natural products by chemical synthesis or chemical separation.
Materials such as cement, lime, paint, glass, and plastic used in modern construction are all chemical products. All kinds of modern transportation used for transportation not only need gasoline and diesel power, but also various gasoline additives, antifreeze, and lubricants for mechanical parts, all of which are petrochemical products. In addition, the medicines that people need, as well as the essential items for daily life, such as detergents, beauty products, and cosmetics, are also chemical agents.

It can be seen that our clothing, food, housing and transportation are all related to chemistry, and everyone needs to use chemicals, so it can be said that we live in the chemical world.

The material of the society, the matter is composed of elementary particles, and different elementary particles form different substances through chemical reactions.
-
The world is made up of microscopic matter, and chemistry is a discipline that studies microscopic things.

1.Chemistry plays an important role in guaranteeing the survival of human beings and continuously improving the quality of life of human beings. Such as:
the use of chemicals to produce fertilizers and pesticides to increase food production; The use of chemical synthesis of drugs to inhibit bacteria and viruses to protect human health; the use of chemistry to develop new energy and new materials to improve the living conditions of human beings; The use of chemistry to comprehensively apply natural resources and protect the environment to make human life better.
2.Chemistry is a practical discipline, which, together with mathematics, physics and other disciplines, has become the foundation for the rapid development of natural sciences. The core knowledge of chemistry has been applied to all areas of the natural sciences, and chemistry is an important pillar of the powerful force that creates and transforms nature.
At present, chemists use the perspective of chemistry to observe and think about social problems, and use the knowledge of chemistry to analyze and solve social problems, such as energy problems, food problems, environmental problems, health problems, resources and sustainable development problems.
3.The intersection and penetration of chemistry and other disciplines have given rise to many marginal disciplines, such as biochemistry, geochemistry, cosmochemistry, ocean chemistry, atmospheric chemistry, etc., which have led to the rapid development of science and technology such as biology, electronics, aerospace, laser, geology, and oceanography.

1. Use chemicals to produce chemical fertilizers and pesticides to increase food production and solve the problem of human food and clothing. 2. The use of chemical synthesis of drugs to inhibit bacteria and viruses and protect human health. 3. Use chemistry to develop new energy and new materials, such as cement, lime, paint, glass, plastic, gasoline, diesel, antifreeze and lubricants, to improve human travel and living conditions.
4. Use chemistry to solve the problem of environmental pollution, so as to protect the environment and make human life better. 5. Use chemistry to develop various food additives, such as sweeteners, preservatives, spices, flavorings and pigments.
Chemistry is a type of natural science. Chemistry is a science that studies the composition, properties, structure and changes of matter at the molecular and atomic levels. As an important bridge between the microscopic and macroscopic material worlds, chemistry is one of the main methods and means for human beings to understand and transform the material world.

First, chemistry is more material**. The common ones are plastic, rubber, polyester, and these things are the basis of many modern products. The new popular ones are graphene, the use of titanium, which is the new darling of aerospace technology and superconducting technology.
Second, chemistry is the cornerstone of modern medicine, and how drugs work in the human body depends largely not on the knowledge of medicine and biology, but on chemistry.
To sum up, chemistry has played an important role in at least transportation, medicine, daily necessities, building materials, etc., so the development of chemistry is naturally the gospel of human social progress.
There will be a market for demand, and now with the influx of most people into the city caused by parking difficulties, and now stolen, stickers of various images have caused the parking space to be high.
Theory of Practice: Human production activities are the most basic practical activities.
Because although people are all the same species, but their environment, status, and economic strength are different, all of this is too realistic, too material, put aside all this, you can say that people live a simpler life, but you can't put these aside, these are the most basic in life, everyone disguises themselves, just like that sentence, men like beauty, women like love words, so men lie, women put on makeup, they all disguise themselves, make themselves complicated, and then get what they want, So there's no way around it.
Because many people maliciously vandalize vehicles, destroy the world, lock the shared bicycles, and smash the locks, the destroyed shared bicycles are everywhere, resulting in a great waste of resources.
These are the exact words of Marx in Capital. If A takes a hour and B an hour to produce a commodity, and the socially necessary labor time for the production of the commodity is c hours (the social average), then according to Marx's labor theory of value, the value of the commodity is determined by c hours, not by the individual labor time of A and B, when the labor time of his production of the commodity is lower than the socially necessary labor time, and the individual value of the commodity he produces is lower than the commodity value of the commodity determined by the socially necessary labor time, Then he will make a super profit by selling the commodity according to its value, and if he does not, he will lose money. Therefore, the practice of reducing the value of commodities to specific labor hours is absurd, because the formation of commodity value is a social process, and the understanding of commodity value cannot only stay on the surface, which is a common problem of anti-Marxists, because they cannot correctly understand and comprehend the essence of labor value, and lack the spirit of in-depth study of knowledge, so they often inflict their own mistakes on Marx, which is very ridiculous.
