Write a paper about the advantages and disadvantages of disposable tableware.
Disposable tableware is hygienic and convenient, but in real life, we found through online investigation and field investigation that its hygiene is greatly reduced. According to the personnel of the National Quality Inspection Bureau, a large number of prohibited materials such as calcium carbonate, talcum powder, industrial paraffin and waste plastics are used in production, which will lead to the mutual dissolution of mineral additives added in lunch boxes and water, vinegar and oil contained in food, which will easily lead to indigestion, local pain and liver system diseases, affecting children's intelligence. Many people like to use disposable chopsticks, thinking that it is convenient and hygienic, and throw them away after use. However, it is this kind of thing that is thrown away after eating that accelerates the destruction of forests. Forests are converters of carbon dioxide, generators of rainfall, generators of floods, and protected areas of biodiversity. These functions can never be replaced by the benefits of producing disposable chopsticks. The large demand for disposable tableware in the market has brought huge profits, which makes the merchants pay close attention to disposable tableware. Merchants will carefully calculate whether it is unprofitable in production and sales, and calculate the size of benefits in order to seek greater benefits and maximize benefits. The blind use of consumers only aims at convenience and convenience, and never pays attention to the hygiene and safety of disposable tableware, which greatly urges merchants to do whatever it takes to squeeze more profits, and only achieve convenience and convenience in production, regardless of whether the hygiene of products meets the standards. Disposable chopsticks are really convenient, but it is an indisputable fact that the hygiene is not up to standard and forest resources are wasted. According to relevant data, China consumes 45 billion pairs of disposable chopsticks and 65.438+0.66 million cubic meters of wood every year, and needs to cut down about 25 million trees and reduce the forest area by 2 million cubic meters. The consumption of disposable foamed plastic tableware is also very large. According to statistics, the consumption of disposable foamed plastic tableware in China is more than 654.38+000 billion. At present, disposable plastics, which are widely used, have become one of the culprits of environmental pollution. According to experts, foaming agent was used in the production of disposable foamed plastic tableware, which destroyed the atmospheric ozone layer. When these tableware are used, once they encounter high temperature, they will produce substances harmful to human health, and after burning, they will produce carcinogenic dioxin, which will take about 200 years to degrade when buried in soil, polluting soil, atmosphere and groundwater, and it is difficult to decompose when buried in soil, resulting in a decrease in soil capacity.

Disposable tableware has many hidden dangers. First of all, about paper tableware. Some underground factories use non-food grade paper to process tableware; Paper tableware generally uses adhesives, and some underground factories often use impurities or toxic adhesives, and even use industrial adhesives; When printing words on tableware, the ink should be food-grade, but some underground factories often use industrial ink, which can easily penetrate into the inner wall of paper tableware and endanger health. Secondly, about plastic tableware. According to national regulations, the main materials for making plastic products that can hold food are polypropylene, polyethylene, polyvinyl chloride and polystyrene. These raw materials are below 85 degrees Celsius, and there is basically no problem. However, some dispersed substances will be produced at high temperature, and monomers such as benzene will dissolve. Third, about disposable chopsticks. Its materials mainly include composite materials, logs and bamboo. The composite material is made by processing some scraps into powder and then compounding, and its adhesive will release toxins when it meets high temperature. In Lanzhou alone, 6.5438+0.5 million pairs of disposable chopsticks are consumed every day, and 20,000 trees are "eaten" every year. Because it is cheap, middle and low-grade restaurants, hot pot restaurants and food stalls entering the city are very popular. Most tables are cheap disposable chopsticks. If consumers want to use slightly better quality chopsticks or sterilized chopsticks, they can only go to a few restaurants or high-end dining places. Each pair of chopsticks is only 0.02 yuan, but because the cost of chopsticks is included in the cost and provided to consumers free of charge, the price is the first. In order to make money, operators of course choose chopsticks that are shoddy but cheap. As we all know, one of the killers of disposable tableware entering the market is its low price. There are mainly three kinds of tableware: foamed lunch boxes, plastic bowls and cups, paper cups and paper bowls, and their wholesale prices are not much different: plastic bowls are 8 cents each, and the retail price is 1 cent each; Plastic cups, paper bowls and cups are fifty or sixty cents each, and the price is very low. For years, there has been a misunderstanding. In other words, the mass production of convenient chopsticks in China is a trampling on the environment and a disrespect for nature. Is the embodiment of quick success and instant benefit. Actually, this view is one-sided. The main raw material of disposable chopsticks is fast-growing wood such as fast-growing poplar. The plan of "Returning Farmland to Forests" vigorously promoted by China government is essentially the popularization of fast-growing tree species. Fast-growing tree species are chosen because their growth cycle is short and they can be planted in a large area in a short time. If ordinary tree species are used, the growth cycle will be long, which will not only fail to achieve the purpose of "afforestation", but also affect the economic interests of farmers in a short time. Many things have happened in many places because farmers can't get real benefits. It is conceivable that the effect of "returning forests" can not be achieved. From a macro point of view, the production of disposable tableware still has advantages and disadvantages.
