The purpose and significance of the study:
Today, with the rapid development of science and technology, nature is polluted, the environment is destroyed, the earth is sighing, the earth is crying, and our lovely home is polluted everywhere. Therefore, environmental problems have become a global problem, and "white pollution", as one of environmental pollution, has also become a hot spot of increasing concern. In order to further understand the harm and formation of "white pollution", I consulted relevant books, collected materials, and conducted a series of investigations and observations under the guidance of teachers, and made a preliminary study on the harm of "white pollution" and its control methods.
Process of carrying out activities:
First of all, make clear what is "white pollution"
When it comes to white pollution, there may be no one who doesn't know them. In our daily life, all kinds of discarded plastic bags, disposable lunch boxes and films in agricultural plastic greenhouses belong to the category of white pollution. But if you ask its exact definition, I'm afraid few people can say it. So, what is white pollution? The so-called white pollution refers to the environmental pollution caused by plastic products made of polyethylene and polystyrene being discarded after use. They are not all white, just because most of the "typical" disposable plastic lunch boxes and plastic packaging bags are white, so they have such a "good name".
Second, what are the hazards of "white pollution"
The first is to destroy the beauty of the environment and produce visual pollution. White plastic bags, lunch boxes, foam packaging materials and other disposable plastic items can be seen everywhere in Longtian Town. Sometimes, walking on the wide road, a gust of wind blows, and I see the plastic bags on the roadside blown into the sky, like a kite with a broken line. "White pollution" decorated rivers, fields and cities with unique landscapes.
Because "white pollution" is difficult to decompose, it will become a killer of animals. I read such a report in the newspaper. Someone found a dead whale in the sea. When dissecting the dead whale, it was found that the whale was stuffed with plastic bags, as well as marine animals such as dolphins and turtles, which were also caused by eating plastic bags by mistake. ...
Third, grasp the reason why white pollution is so rampant.
This mainly comes from our life. In China, disposable items are increasing day by day, and the most common one is fast food box lunch. To this end, we conducted a survey and statistics on the use of fast food boxes in some fast food restaurants in Longtian. Each fast food restaurant uses an average of 50 fast food boxes every day. In some schools, there are about 20 fast food restaurants, which use 65,438+0,000 fast food boxes every day. Then in 1 month, I wonder how many disposable fast food boxes will become the chief culprit of "white pollution" in fast food restaurants in the whole city and town. Now, whether buying vegetables, fruits or other commodities, sellers are packed in plastic bags.
Fourth, our actions.
1, collecting data
These are the "white pollution" on the streets that we photographed in Longtian. During the investigation, all members of our team went to Longtian Street to take photos of white pollution on March 24th, 2005. These are three of them that we selected. In the street, we saw a large number of plastic products circulating in the market. In the bustling crowd, shining silver plastic belts are demonstrating to us. Let's take a quick snapshot and never let go of a clue. We also saw many smelly garbage dumps in the street. Among them, white is dominant, and people passing by all bow to its unbearable smell! But who is not the maker of this smell?
2. Interviews and surveys
In the process of researching the subject, we interviewed the supermarkets near Longtian Town, focusing on the number of plastic belts they use every day.
Venue: Lerongrong Supermarket
Shop assistant: Miss Lin.
Problem: under normal circumstances, the number of plastic belts is about 300, and it can reach 500~600 when it is busy.
The bigger supermarkets in Longtian Town are: happy, profitable, profitable …
After investigation, the usage of their plastic belts is similar to that of Le Rong Rong, among which the benefits are the most. According to statistics, only these supermarkets can use more than one thousand a day, which is equivalent to the usage of 600~700 households.
It can be seen from this small survey that the degree of white pollution in other places should be more serious. Therefore, it is urgent to stop the spread and development of the white devils.
In addition, we also interviewed passers-by, mainly focusing on the following questions.
(1) Do you know what white pollution includes?
Do you think it is right to use plastic products?
⑶ What do you think is the harm of white pollutants?
In view of the above problems, we were going to interview 50 passers-by, and only 40 people were interviewed. According to statistics, 60% of them are familiar with white pollution, 30% are familiar with it, and 10% hardly know it. As for whether to use plastic products, 100% people are using them, and 89% people think that plastic products should be used.
3. Active publicity
As can be seen from the above survey, the knowledge of white pollution is not universal, and a large number of people do not know it very well. Therefore, we should intensify propaganda, instill relevant knowledge into people, and make people realize the urgency of controlling white pollution. We should start from ourselves, start from the small things around us, do not use or use less things that will cause white pollution, and wish our home a better place.
Verb (abbreviation for verb) Our suggestion:
How can we reduce and control "white pollution"? After investigation and study, we put forward the following suggestions:
First of all, reduce the consumption in life, and use less or no plastic bags at ordinary times. Everyone should take active actions, starting from me, starting from the side, taking a cloth bag or basket when shopping, and eating a bowl of fast food … these are all very simple for us. If everyone uses one less plastic bag every day, the city will reduce 630 thousand plastic bag garbage every day.
Secondly, it is suggested that manufacturers of plastic products should use new biodegradable materials when making disposable plastic packaging, which will be decomposed by microorganisms in a short time and have little impact on the environment.
Thirdly, it is suggested that the environmental protection department should separate plastic products from garbage in addition to classifying garbage; We should also strengthen the recycling of waste plastics and concentrate them for unified treatment. The raw material of plastics is petroleum, and modern technology has been able to reduce plastics into petroleum, so this technology should be popularized and applied quickly.
What should we do as teenagers:
1. Try not to use or use less disposable tableware when the existing ban is not effectively implemented; You can bring your own shopping bag when you visit the supermarket.
2. Don't throw white garbage, improve the utilization rate of plastic products, and try your best to let others use less disposable plastic products.
We believe that with the attention of relevant departments, we in Qi Xin will work together to turn our good wishes into concrete actions. In the near future, the deadly enemy of the environment-"white pollution" will be reduced or even completely eliminated.
In order to have a clean and beautiful home, please act!
Finally, I hope more people of insight will embark on the long journey of eliminating "white pollution" and jointly draw a clean and beautiful new world.
