With the improvement of people's living standards and the growth of population, more and more waste products are abandoned to nature by human beings, and nature has been scarred. Untreated factory waste, waste residue and domestic garbage are simply piled up in the open air, occupying land and destroying the landscape. Moreover, the harmful components in the garbage drift with the wind and enter the soil, rivers or underground water sources after the rain, which brings serious pollution to the urban environment and seriously endangers human life and health.
Garbage is a misplaced resource and a raw material mine that will be used one day. However, the substance content in recycled raw materials or wastes is a key factor, because the value of recycled wastes depends on its substance content. If the material content in the recycled resources is too low, the collection cost will be too high, such as the sorting of waste steel and waste plastics, and the transportation cost will be higher. Mixed into garbage, divided into resources, a lot of garbage can not be reused because there is no classification.
Under the guidance of the teacher, I made a survey of the communities where our classmates and parents lived. Some problems were found as follows.
Ignorant behavior, shame!
I made a survey among my classmates and found that many behaviors in our lives are very environmentally unfriendly. For example, 95% people mix recyclable garbage with non-recyclable garbage. "Mixed", so this is the main reason for paper pollution! If people sort and recycle garbage, white pollution will greatly reduce the natural environment, and our living environment will be very different. In life, for convenience, many seemingly ordinary things have done harm to our nature to varying degrees. In modern life, disposable articles are easy to use, but there are also problems that cannot be ignored. Disposable articles waste resources and pollute the environment. For example, in our daily life, drinking cups are essential. But how to choose a cup to drink water? For convenience, almost every household uses disposable paper cups. Everyone says it's convenient and cheap. But it is precisely because of the emergence of disposable paper cups that the environment around us has been greatly damaged. Citizens use disposable paper cups and throw them around, causing serious environmental pollution.
The price of waste products has dropped, which is sad!
It turns out that the garbage collection station in our life plays a very important role in garbage classification, which not only saves resources, reduces the harm of garbage to the environment, but also mobilizes us to classify useful resources consciously. But now garbage collection faces a difficult problem. According to my mother, she used to sell waste paper boards, waste glass, waste metal and waste plastics to waste recycling stations, but now the price of waste products is very cheap, which makes her flinch. Waste newspapers dropped from 2 yuan to 0.8 yuan per kilogram1. The cans were reduced from 0. 1 yuan per can to 0.03 yuan; The number of mineral water bottles decreased from 1 angle to 1 angle. As a result, my mother sometimes refuses to pick up the waste bottles when she sees them. The price of waste recycling has plummeted all the way, which has led to a decline in consumers' enthusiasm for trading, and recycling companies are afraid to continue recycling waste. Such a vicious circle will inevitably lead to a new round of environmental pollution.
Born victim, poor guy!
"Fish swimming in Qinglingling River" is out of sight, and the water has been seriously polluted. Maybe you will say, isn't there bottled drinking water? But drinking bottled water is not the best way to solve water pollution, and drinking bottled water also needs water resources. And drinking bottled drinking water is not very healthy for people's health. The river is turbid, and there is a lot of plastic garbage floating on the water surface, which has an unpleasant smell from time to time. Because people throw garbage into the river at will, the factories along the river have not passed the qualified filtration, and wastewater and waste products are discharged into the river, and the originally clear river water has become "Heilongjiang".
Toxic waste, terrible!
In the past, due to the relatively small population and low productivity, the amount of waste produced was not much, and highly toxic waste was not common. With the chemical revolution in 1930s and the nuclear industry after it, more and more toxic wastes were produced and manufactured. Among them, the main toxins are: dioxins, which come from plastic products and industrial waste, seriously damage the nervous system of people and animals, leading to cancer and other diseases; Mercury from waste batteries makes people osteoporosis, deform and destroy the nervous system; Organic chemicals come from wastewater discharged from chemical, pharmaceutical and paper mills, which can seriously deteriorate water quality, kill aquatic organisms, enrich in animals and plants, and lead to chronic poisoning of human beings. Waste building materials and home decoration waste also contain such substances; Other garbage, such as fluorescent tubes, contains a variety of heavy metals and organic substances, such as lead, mercury, cadmium, etc., which cause diseases of nervous system, digestion, circulation and other physiological systems. The danger of nuclear waste can be maintained for thousands of years, and it is the most threatening toxic waste. In addition, garbage can produce many toxic compounds twice, which seriously endangers the safety of animals, plants and human beings in nature. Therefore, we advocate garbage classification, reduce toxins, reduce the amount of garbage and reuse it.
Environmental action can!
Some simple changes can reduce energy consumption. For example, office workers who are close to home can commute by bike without driving; Choose trains instead of planes for short trips; When it is not necessary to continue charging, unplug the charger from the socket; If you don't use the computer within an hour, turn off the host and monitor conveniently; Taking a shower instead of bathing every day can reduce carbon dioxide emissions by about 0. 1 ton per person throughout the year. ...
Garbage sorting can recycle valuable resources and reduce the energy consumed by landfill and incineration. For example, waste paper is sent directly to a paper mill to produce recycled paper; Beverage bottles, cans and plastics can also be sent to related factories to become renewable resources; Household appliances can be sent to specialized manufacturers for decomposition and recycling. Different garbage bags can be prepared at home to collect waste paper, plastic, packaging boxes, kitchen waste and so on.
Shopping malls are full of disposable items: disposable tableware, disposable toothbrushes, disposable signature pens ... disposable items bring temporary convenience to people, but bring disasters to the ecological environment. They accelerate the depletion of the earth's resources, and produce a large amount of garbage that causes environmental pollution.
Environmental quality can be improved!
Active environmental publicity and education plays a very important role in improving the environment and promoting environmental protection. 1992, "Agenda 2 1 Century" published by the United Nations Conference on Environment and Development pointed out: "Environmental education is very important for promoting sustainable development and making effective reference for the public." The agenda suggests "adjusting the direction of education to adapt to sustainable development, raising public awareness and promoting training". At present, in China, people's understanding of the internal relationship between human activities and the environment is still quite poor. Because of the special resources, environment and population situation in China, environmental publicity and education is more important. Through active environmental protection propaganda, people can realize the harmfulness of environmental damage and the importance of environmental protection, and then further understand and care about the interdependence of economy, society, politics and ecology, enhance everyone's sense of responsibility, and acquire knowledge and skills to protect and improve the environment and support sustainable development.
