Aloe vera can absorb large amounts of indoor formaldehyde and other pollutants, thereby eliminating and preventing indoor air pollution. Under 24-hour lighting conditions, aloe vera can remove 90% of formaldehyde contained in 1 cubic meter of air. Ordinary aloe vera can not only fight bacteria and other harmful substances brought from the street, but can even absorb dust that even a vacuum cleaner cannot absorb more than 80% of indoor harmful gases. In a 15 square meter room, planting two pots of Sansevieria can keep the air fresh and free from the harm of formaldehyde. Sansevieria can also release a large amount of oxygen during the day. Placing a pot of Sansevieria orchid in the study room, as cheerful as a thousand arrows shot, can relieve the fatigue of those who work in the office and stimulate creative enthusiasm and fanciful ideas. Cacti ManyPlants open their stomata during the day, while cacti open their stomata at night. Because cooler temperatures at night, lack of sunlight, and light breezes help cacti retain water. But at night, cacti can't use solar energy to convert carbon dioxide into the sugars they need. They must therefore store part of the carbon dioxide to use it the next day. Therefore, cacti can absorb carbon dioxide at night, which is beneficial for sleep. It also has a strong ability to absorb harmful gases or absorb smoke and dust. Dieffenbachia is an evergreen, shade-tolerant plant suitable for indoor planting and a pioneer in the fight against air pollution. It can effectively remove indoor pollution such as trichlorethylene, hydrosulfideene, benzene, phenol, hydrogen fluoride and ether. Put a pot of dieffenbachia in the bedroom to relax your body and mind and gradually fall asleep. Alocasia sylvestris has become one of the most popular indoor potted foliage plants. It uses its large, beautiful leaves to increase air humidity and absorb large amounts of formaldehyde and ammonia. The more leaves, the more powerful it is in filtering, purifying and hydrating the air. Chlorophytum is not only an excellent plant with hanging foliage in the room, but also a good indoor air purifying flower. Spider plants have a strong ability to absorb toxic gases and can purify toxic gases such as carbon monoxide, carbon dioxide and formaldehyde. Generally, if you keep 1-2 pots of spider plants in a room, they can absorb all the toxic gases near them.ents in the air. This is why spider plants are also known as “green purifiers”. The iron tree can decompose two harmful substances, namely formaldehyde found in carpets, insulation materials and plywood, and xylene hidden in wallpaper, which is harmful to the kidneys. Pothos is an evergreen plant that can eliminate several toxic chemicals inside buildings. Pothos can remove formaldehyde and benzene molecules in the room. ivy, chrysanthemumGerbera (Gerbera) flowers also have this effect. The money tree is evergreen all year round and can absorb toxic gases and release oxygen through photosynthesis. In addition, camellia, cyclamen, violet, tuberose, dianthus, gladiolus, etc. can absorb harmful gases through their leaves; jasmine, lilac, honeysuckle, the glory ofMorning and other flowers secrete fungicides that can kill bacteria in the air and inhibit growth. pathogens of tuberculosis, dysentery and typhoid bacteria, make the indoor air of the family clean and hygienic and prevent diseases; osmanthus, winter sweet, taro, red-backed osmanthus, etc. are natural dust collectors, and their cilia can intercept and absorb dust. in the air. Floating particles and smoke.
1. The sun is the origin of human life; the origin of life requires energy, and the maintenance and continuation of life also requires energy. Certain temperature conditions are also necessary for the survival and sustainability of organisms. At a minimum, the water should remain liquid. The sun brings us heat and light and provides the necessary energy. Sunlight can give people warmth, improve blood circulation and fpromote normal secretion of sweat and sebum. Sunlight can kill bacteria and maintain normal bacterial flora on the surface of human skin. Photosynthetic organisms form the basis of the food chain. Energy on earth is provided directly or indirectly by sunlight.
2. Many geological and meteorological disasters on earth are linked to solar activities, such as solar wind, sunspots, solar flares, etc.
3. Today, with scientific and technological equipment, people have expanded the direct or indirect use of solar energy. The simplest is solar water heaters, then solar power generation, which uses solar energy to run vehicles.
4. Food sources and material sources. Without the sun, there would be no animals or plants, and humans would have no food. OfMoreover, there would be no materials in which humans could wear and live.
The Sun is a huge nuclear fusion reactor, which mainly fuses hydrogen into helium and emits enormous energy. It illuminates our earth with its light and constitutes the main source of earth energy. Solar radiation consists mainly of visible light, but also includes infrared rays and ultraviolet rays. Visible light accounts for 50% of total solar radiation, infrared rays account for 43%, and the ultraviolet region accounts for only 7% of the energy. According to rough estimates, the thermal energy supplied by the sun to the earth every minute is about 25 billion calories, which is equivalent to the energy generated by burning 400 million tons of bituminous coal. At the average distance between the sun and the earth, the solar radiation energy received per unit areaperpendicular to solar radiation at the upper limit of the Earth's atmosphere is 1,353 watts per square meter, which is quite considerable. the surface of the Earth is due to the influence of the atmosphere and dust. Reflection and refraction exhibit some attenuation, which varies with latitude. Coal and oil are solar energy dating back hundreds of millions of years and preserved as biological fossils. Wind power and hydropower are ultimately forms of solar energy conversion.
