Cities provide people with housing, jobs, opportunities for entertainment, and a comfortable life, but they have a bad effect on people's bodies and minds every minute in a silent way that is not noticed at all. At the very least, living and working in a building with open windows, where the sun never enters, can no longer receive the heat energy of the sun, which is the source of life, and is a source of vitamin deficiency and various diseases.

The air in big cities is polluted with dust, lead and other harmful substances with little oxygen. This can be determined by the above indicator being 100 times higher than the air temperature of 1 square kilometer of rural land. By breathing in such dirty air, we get several diseases such as respiratory diseases, bronchial asthma, colds, and allergies, and are exposed to hundreds of bacterial infections.

Big city sounds. We are used to accepting this noise as an integral part of the city. People do not know that this sound directly affects the human nervous system, brain and heart. Such infrasound, inaudible to the ear, can make people tired, chronic fatigue, anxiety, headaches, vision impairment, blindness, and even cardiac arrest.
Residents of big cities are constantly exposed to electromagnetic radiation. Sources of this radiation include power lines, antennas, high-frequency equipment in factories, household appliances, cell phones, and countless other devices. Scientists have determined that these have a very bad effect on the human body and create conditions for cancer, birth defects, and mutations.

Decreased birth rate. This is believed to be related to the stress, ecology, and urbanization of urban living conditions, which affect people living in large cities and make them less likely to give birth and procreate.

Stone fighting. It is considered that the visual information received by the residents of big cities is a stress factor. Monotonous squares, predominantly gray, and stereotyped houses with the same design create a feeling of perception of neighborhoods and cities as a stone war, and have a heavy impact on the psyche.

In addition, large cities have countless negative aspects, such as the high density of urban population, dangerous crime-prone areas, and tap water, the source of drinking water that comes through several kilometers of pipes. However, the strange thing is that the majority of the world's population does not think about any other life than aspiring to live in a big city. However, research has shown that wealthy people aspire to a life close to the countryside and nature.
