Plastic bags do bring convenience to our lives, but the convenience of this moment but bring long-term harm.
Plastic bags have a low recycling value, in the process of use, in addition to scattered in the city streets, tourist areas, bodies of water, highways and railroads on both sides of the pollution caused by "visual pollution" pollution, it also exists a potential hazard. The structure of plastic is stable, not easy to be degraded by natural microorganisms, in the natural environment for a long time without separation. This means that waste plastic waste, if not recycled, will become pollutants in the environment permanently exist and continue to accumulate, will cause great harm to the environment.
First, it affects agricultural development. Waste plastic products mixed in the soil continues to accumulate, will affect the crops to absorb nutrients and water, resulting in crop yield reduction.
Secondly, it poses a threat to the survival of animals. Abandoned on land or in the water body of waste plastic products, swallowed by animals as food, resulting in animal deaths. 2010 Qinghai Lake, 20 herdsmen *** have nearly a thousand sheep died as a result of this, the economic loss of about more than 300,000 yuan. Sheep like to eat plastic bags wrapped in oily residue, but often even plastic bags eaten together, due to eat plastic for a long time to stay in the stomach is difficult to digest, these sheep's stomach was crowded, no longer able to eat, and finally can only be alive and starve to death. Such things are common in zoos, pastoral areas, rural areas and oceans.
Thirdly, waste plastics landfilled with garbage will not only occupy a large amount of land, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. Into the domestic waste of waste plastic products if the landfill, 200 years of time does not degrade.
There is great harm to the land, changing its pH, affecting the absorption of nutrients and water by crops, leading to a reduction in agricultural
Industry, as for the abandonment of plastic products in the water or land, not only affects the environment, but also if swallowed by the passive, it will lead to death. This destroys the ecological balance.
Fourth, high temperature decomposition of toxic substances, plastic products are non-toxic substances, but because of its recycling and reuseuse of equipment is not perfect, poor technology, and many manufacturers do not have a legal business license, resulting in reproduction of
Plastic products at a temperature of 65 ° C, the poisonous substances will be precipitated and seeped into the food, then the liver, kidneys, reproductive system and central nervous system and other important parts of the human body, the liver, kidney and other important parts of the human body, the liver, kidney and central nervous system. and the central nervous system and other important parts of the human body to cause harm.
China recently by the State Council General Office of the People's Government of the provinces, autonomous regions and municipalities directly under the Central Government, the State Council ministries, commissions and agencies directly under the Central Government issued a "restriction on the production and sale of plastic shopping bags on the use of the notice". The notice pointed out that: in view of the shopping bag has become a "white pollution" the main source of the future of the people's governments around the world, ministries and commissions should be prohibited from the production, sale and use of ultra-thin plastic shopping bags, and will implement the system of paid use of plastic shopping bags. Since June 1, 2008 onwards, in all supermarkets, shopping malls, markets and other commodities retail places to implement the system of paid use of plastic shopping bags, shall not provide free plastic shopping bags.
Plastic bags play an indispensable role in our lives, our country every year to consume a large number of plastic bags. In our country, every day just to buy food to use up 1 billion plastic bags, as for other kinds of plastic bags in the amount of more than 2 billion every day. To the supermarket, the market shopping by the merchants to provide plastic bags, has long been a habit of our lives.
But plastic bags provide convenience for consumers at the same time, but also because of excessive use and recycling is not easy to deal with and other reasons, resulting in a serious waste of energy resources and environmental pollution. In particular, ultra-thin plastic bags are easy to break, coupled with our people's environmental awareness is weak, after the use of most of the randomly discarded, scattered in the city streets, tourist areas, water bodies, highways and railroads on both sides of the "visual pollution" and become "white pollution". It has become the main source of "white pollution". More and more countries and regions have restricted the production, sale and use of plastic shopping bags.
China's restriction on plastic bags means that our living habits will inevitably change, and we will have to return to the life of carrying a basket of food. So it triggered a lot of opinions and comments. Some of them may be accustomed to the convenience of plastic bags in life, ignoring the harm it causes and opposing views.
The plastic bag was invented on October 24, 1902 by Austrian scientist Max Schuschny. This kind of packaging is both lightweight and strong, loved by customers and merchants. Therefore, stores, food courts have to provide free plastic bags. But this invention has brought us serious environmental problems 100 years later.
Because most plastic bags are produced from non-renewable degradable materials, the plastic is structurally stable and not easily degraded by natural microorganisms that are difficult to separate in the natural environment. Handling these white trash can only dig landfill or high temperature incineration. These two methods are not conducive to environmental protection. The landfill of waste plastics will not only occupy a large amount of land, and the occupied land will not be restored for a long time. Plastic bags buried in the ground, it takes more than 200 years to decay, which is extremely harmful to the land, will change the pH of the land, seriously polluting the soil, affecting the absorption of nutrients and water by the crops, leading to a reduction in agricultural yields, and affecting the sustainable use of land. And incineration of harmful soot and toxic gases, the same will also cause pollution of the atmospheric environment. So now plastic bags have become the 20th century mankind's "worst invention".
The implementation of the plastic bag ban is aimed at solving or alleviating a series of environmental problems brought about by the excessive use of plastic bags. From June 1, 2008, everything will be different. Thickness of less than 0.025 millimeters of plastic bags that ultra-thin plastic bags will be banned from production, sale, use. In order to improve the service life of plastic bags, so that people use reasonable and economical use of plastic bags to reduce pollution. All supermarkets, shopping malls, markets and other commodity retail places will no longer provide free plastic bags, and promote consumers to pick up the cloth bag, heavy pay raise the food basket, reuse durable shopping bags, in order to reduce the use of plastic bags.
Environmental protection is not a person or two people's business but everyone's business, the country's business, the business of future generations, the need for the whole society to act together *** with the participation. We only have a planet, from the perspective of sustainable development, plastic restriction will be a measure to benefit future generations of children and grandchildren. Perhaps in the near future, plastic bags will disappear from our lives.
Everyone is responsible for caring for the environment! Let's free ourselves from the confinement of using plastic bags!
Correction fluid as long as the component: paraxylene, long-term use can be on the liver, kidneys and so on to cause long-term chronic harm, and even a few children will cause like leukemia and other symptoms. Next is a variety of halogenated hydrocarbons. Including dichloroethane, trichloroethane, tetrachloroethane, etc., these compounds have a very obvious eye irritation, frequent use will cause tearing, eye redness, individual will also cause nausea, vomiting, body discomfort, and even cause some more serious long-term harm, dry quickly is a merit of the correction fluid, because it contains volatile organic hydrocarbon substances, and because of this, it will cause more obvious harm to the child's five senses. The child's five senses will cause more obvious damage, reinforcing its toxicity penetration.
