Everything in the world cannot be separated from air, sunlight and water. It is the air, sunlight and water that nourishes and warms the earth, so that plants can grow, animals can be found, and humans can be found. Human survival is also inseparable from air, sunlight and water. In the absence of air, lack of oxygen, people will soon die of suffocation; sunlight brings warmth to humans, humans live on the earth because the sun is not far from the average annual temperature of 17 °, there is a suitable temperature for the growth of everything, the snow is impossible to grow the food necessary to maintain life; blazing hot weather, will be a lot of evaporation of water, so that the land dry, sandy, also impossible to grow the food necessary to maintain life. It is also impossible to grow the food necessary to sustain life. The right temperature not only warms the earth and grows food for human survival, but also nourishes the animals and humans on earth. Nature’s various plants, because there is sufficient water nourishment, irrigation, in order to grow. Humans are not only inseparable from water, but also inseparable from the constant source of energy provided by plants and animals to the human body. With the progress of the times, high technology is widely used in life. Nowadays, people are constantly seeking for new and different things. People’s living environment, living environment and diet structure are undergoing many changes. Various media are constantly transmitting various information to everyone, and the ever-changing life represents fashion and high quality of life. People’s life is enjoying a high degree of modernization, but various diseases are rising, difficult and incurable diseases more and more, the age of onset is getting younger and younger, children now do not see the white and red face, young people now have no vitality, and how many middle-aged people are healthy and disease free? Now the elderly have put all their energy on health care, according to the media publicity of various health care methods, daily serious maintenance of their bodies, may be healthy to live to 100 years old and how many elderly people? Why in the rapid development of science and technology today, human diseases are not only not effectively controlled and cured, but the body’s physical fitness, physical fitness are declining, bent on the human determinism of the human should not reflect on it? The development of all things should be in accordance with the laws of natural development, such as air, sunlight and water is the fundamental growth of all things and human beings. Now people live in closed houses for a long time, can not breathe fresh air, but breathe high-tech to send you through the machine treatment, processing of air; sunlight brings us the appropriate temperature of the earth, the earth in the process of orbiting the sun in a year, due to the different distances, the temperature will change, spring, summer, autumn, winter different seasons have been accompanied by the earth for millions of years, but now people use High-tech, so that people live in the artificial environment of the four seasons, but also produced a variety of anti-seasonal food for human consumption; water is a necessity for human survival, high-tech has been simple rainwater, groundwater, river water, spring water and other kinds of natural water, with human ingenuity and wisdom, adding elements that they believe are essential to the human body, the production of thousands of various kinds of water, drinks; human survival of energy is larger than the natural The energy of human survival is more complex than the natural growth of plants, not only to eat plants that can be beneficial to the body, but also to raise a large number of animals for human consumption, smart people can eat all kinds of plants, animals, but put a lot of effort on high-tech production of pesticides, fertilizers, drugs, etc., with the concept of “more, faster, better, less” to produce We human survival food, so that our bodies, organs, blood are left with a variety of high-tech production of a variety of chemicals, poisoning our bodies. In modern times, the most basic conditions for survival: air, sunlight, water and food are all ruled by high technology. When high technology has separated natural people from nature, it is also far from the most basic conditions for human survival. Once, I saw a 12-year-old girl, her face was white and gray, the child did not even have the strength to stand, very weak. The mother of the child, she went to work in the field for two years, the child followed the father’s life, the father is busy, give the child money every day, let the child solve their own food problems, the child hungry snacks, instant noodles, thirsty drinks, as long as the child every day to fill the stomach, the parents are relieved. However, 2 years later, many lymph nodes appeared on the child’s head and neck, and the child was examined by the hospital for lymphoma. Whenever I go to the supermarket, I see a wide range of beautifully packaged food, I can’t resist the temptation, but every time I eat these foods with too many chemicals added, I always feel sick, it’s the discomfort that makes me honest. Whenever I see people buying all kinds of delicious food in big bags, I really worry about their health and the future of these children who eat snacks and drink drinks. Man is a product of nature, to be healthy and to keep humans away from diseases, we must follow the laws of natural development, return to nature, respect the body’s need for fresh air, clean water, pure food, respect the changes in temperature in all seasons, adapt to the changes in the seasons, and stay away from air conditioning, which is fundamental for humans to get healthy and stay away from diseases. People who love life and body, please go to nature more often to breathe fresh air, open the windows at home, keep the indoor air fresh, drink more plain water, try to drink less processed and treated water and drinks, try to choose safe and less polluted food, do the processing by yourself, do what your body needs most for yourself, your family and your children’s body, and it is not difficult to do all this, life Life will become easier, and the cost will be much less, while the body will be more and more healthy.
