Indoor environmental protection, a new industry with a critical well blow-out, is a human tragedy of indoor pollution that is imminent. As the heat of urban renovations continues to rise, the problem of indoor environmental pollution caused by renovations (construction materials, furniture, furnishings, etc.) has become more acute, seriously affecting the physical and mental health of the population and even endangering life. At present, more than 70 per cent of the country's households are overstretched, and 34 per cent are seriously overstretched by 16-40 times. On the other hand, the household green product usage rate is less than 0. 03 per cent, and the total market size of our indoor environmental clean-up industry in 2006 was as high as 20 billion dollars. People say that life is good and new houses are available, but they dare not. Ninety per cent of the time is spent indoors, working, learning, resting, especially for the elderly and children, with low resistance and immunity, which can withstand the poison of harmful gases such as formaldehyde and benzene. Indoor environmental problems have become more serious, and we are willing to spend money and energy to address them. According to the expert, the concept of greening is gaining ground, with traditional governance focusing more on the outdoor environment and neglecting the indoors. It is now a warning and a reminder to the public that indoor environmental pollution is no less important and must now be addressed. Indoor pollution is a potentially new industry today, and demand is on the rise! As the merchants say: indoor pollution** is an effective business opportunity. Demand is strong and the market is larger with the number of houses. Policies encourage, support and, with these advantages, can be described as windy. New industries, lucrative, little risk, can quickly achieve the "found the first" bet in the short term: the amount of investment in the project, the number of union stores, the number of trade unions and the mode of business, subject to more recent advice!
