(1) There are many disposable items in our life. Such as disposable chopsticks, disposable shoe covers, disposable ballpoint pens, disposable lighters, disposable razors, disposable lunch boxes, disposable tablecloths, etc. Disposable articles have become an indispensable thing in our life.

Although disposable items are convenient, fast and hygienic to use, they are also quickly discarded. After being discarded, it has to spend a lot of manpower, material resources and financial resources to remove and deal with it, which will bring great crisis to human beings and nature.

According to relevant data, China's annual consumption of paper tableware is more than 654.38+0 billion, disposable cups are 20 billion, and disposable tablecloths, shopping bags and other plastic products reach hundreds of thousands of tons? In .................................................................................................................................................................................., China consumes 45 billion pairs of disposable chopsticks every year. If these chopsticks are connected end to end, it is equivalent to 330 laps around the equator of the earth.

Disposable wooden chopsticks account for 16.55% of the forest coverage in China, but China is a big exporter of disposable wooden chopsticks. The disposable chopsticks industry in northern China exports 654.38+0.5 billion Shuang Mu chopsticks to Japan and South Korea every year, with 65.438+0.3 million cubic meters of consumables, which is equivalent to reducing the forest reserves by 2 million cubic meters. Chopsticks are fumigated and bleached with sulfur dioxide during processing. The longer the fumigation time, the whiter the chopsticks and the more sour the smell. Manufacturers usually ignore the boiling step after sulfur dioxide fumigation and bleaching. Residual sulfur dioxide combined with other substances will become sulfite, which is considered to cause asthma in the medical field. At the same time, the transportation and wholesale procedures of disposable chopsticks are complicated, and the whole process is handled by different people many times. Moreover, in order to prevent moisture and insects, different drugs will be sprinkled during transportation and storage. Disposable chopsticks not only fail to meet the sensory and physical and chemical indicators, but also fail to meet the most basic health indicators such as bacterial content, which poses great health risks and is the medium leading to the occurrence and spread of various diseases.

It can be seen that disposable products not only destroy the environment, but also bring great harm to human survival. For the sake of our home, we should use less disposable items. Going to the hotel to bring your own necessities such as toothbrushes and towels will save a lot of energy and resources. Disposable articles do more harm than good. Please use less disposable goods. In essential industries, such as medicine, disposable products should be avoided in other industries. If so, our environment can be protected.

(2) Students, have you ever seen such a scene in your life: the floor of the restaurant is full of used disposable chopsticks; Used disposable lunch boxes are floating on the green water, and disposable plastic bags are flying in the wind ... Seeing these, maybe we are all numb. Yes, this phenomenon is everywhere. Who will be surprised?

In fact, disposable items are really convenient. Disposable chopsticks without washing; Disposable tablecloth, simple to use, no need to change and clean; Lightweight disposable lunch boxes ..... all these reflect the benefits of disposable items.

However, many people only see the benefits of disposable goods and ignore its disadvantages. Take disposable chopsticks as an example!

A big tree that has grown for 20 years can only be made into 3000-4000 pairs of chopsticks. However, China now produces about 45 billion pairs of disposable chopsticks every year and needs to cut down 25 million trees. The forest coverage rate of China is only 16.55%, but it is a big exporter of disposable wooden chopsticks. The disposable chopsticks industry in northern China exports 654.38+0.5 billion Japanese chopsticks to and South Korea every year, and the consumables are 65.438+0.3 million cubic meters, which is equivalent to reducing the forest stock by 2 million cubic meters. According to the survey, there are thousands of enterprises producing wooden chopsticks in China, which consume nearly 5 million cubic meters of forest resources every year. The annual forest harvesting in China is about 47.58 million cubic meters, and these chopsticks account for 10.5%. In the process of producing chopsticks, from logs to blocks to finished products, the effective utilization rate of wood is only 60%.

What amazing data!

As for disposable chopsticks, there is so much waste from production to utilization, not to mention others.

Yes, disposable goods do meet people's special needs to a certain extent, but they also waste a lot of energy and resources, create a lot of garbage, increase the burden on the environment, and even pollute the environment.

It can be seen that disposable products do more harm than good.

It is our bounden duty to protect the environment and save resources. If you consciously don't use disposable chopsticks, disposable fast food boxes and disposable plastic bags, try to use cloth bags when you go out shopping; When traveling, bring your own water bottle to drink, use less paper cups, paper plates and plastic wrap to reduce the garbage generated by plastic beverage bottles; Use towels instead of paper towels; Use less wooden pencils, choose mechanical pencil, use pens as much as possible, and use less disposable ballpoint pens ... How many natural resources and rubbish will the 65,438+30 million young pioneers in China save! Students, let's all take action, join the environmental protection team, take an active part in activities to protect the earth, take the initiative to remove white garbage, erect a small team flag, and carry out a variety of environmental protection activities, from refusing to use disposable goods to striving for a natural and harmonious living space with fresh air, clear water, lush trees and flowers everywhere, so as to be environmental protection masters in the new century.

negative impact

I once read a report that a person often feels stomachache, indigestion and even malnutrition. After going to the hospital for examination, I found a thick layer of wax attached to the inner wall of my stomach. Later, after analysis, he learned that the formation of wax layer originated from his irregular diet and eating a lot of barrel surface. In order to make the paper waterproof, the inner wall of the barrel surface was coated with a thick wax layer. After melting at high temperature, the wax is cooled to the curing temperature and solidified again.

In fact, many paper disposable articles we usually use need waxing. Disposable cups, disposable paper tray, etc. , the impact is not big, it is harmful for a long time, and it is very big. The disposable appearance should be said to have advantages and disadvantages. Too much resources and energy are wasted in the production of disposable goods, which is not only a great waste, but also a harmful injury. This kind of thing needs us to choose to use and develop. We should pay more attention to its harm or influence, and don't rely too much on those superficial conveniences. One-time injuries are not caused by one-time use, so don't spend more time and experience on superficial articles.

Plastic products made of polystyrene, polypropylene, polyvinyl chloride and other polymer compounds for disposable plastic tableware have the characteristics of low toxicity, high melting point, strong plasticity and simple manufacture, and become excellent materials for making disposable lunch boxes, with low price and disposable use. However, disposable plastic tableware not only brings us convenience, but also produces many side effects, which constitute direct pollution to human body and secondary pollution to the environment: disposable foamed tableware consumes a lot of foaming agent, a substance that consumes the ozone layer, thus endangering the earth's umbrella-the ozone layer; As our government has begun to restrict the production of disposable foamed tableware, there are many lunch boxes produced by illegal manufacturers on the market. As a result, product quality, especially hygiene, has also become a problem; Toxic and harmful substances (such as foaming agent) will be dissolved at high temperature and absorbed by food, thus causing trace pollution to human body and damaging health for a long time. If harmful substances exceed the standard, the harm is even greater; The degradation cycle of lunch boxes made of polystyrene is particularly long, which can reach about 200 years in ordinary environment. In other words, for a long time, it will "go its own way" and keep its polymer morphology unchanged. Therefore, it not only destroys the environment, but also brings great harm to human survival.

The forest coverage rate of disposable wooden chopsticks in China is only 16.55%, but it is a big exporter of disposable wooden chopsticks. The disposable chopsticks industry in northern China exports 654.38+0.5 billion Shuang Mu chopsticks to Japan and South Korea every year, with 65.438+0.3 million cubic meters of consumables, which is equivalent to reducing the forest stock by 2 million cubic meters.

Unqualified disposable articles will not only do harm to human body, but also cause waste and pollution. After disposable products are discarded, it usually needs a lot of manpower, material resources and financial resources to remove and deal with them. Ms. Li, the financial controller of a company. There are many disposable items in her family, and she often travels there. She pointed to a "six-in-one" suit with toothbrush, toothpaste, shower gel, shampoo, soap and comb. The chemical fiber hair on the white toothbrush is as hard as steel wire; Toothpaste looks similar to batter; Small square soap has a pungent smell ... She said that these unqualified things will certainly consume a lot of manpower and material resources when they are produced, but after they are produced, they have no use value, which is simply a waste, a waste.
