Investigation report on the use of plastic bags in the big age vegetable market

In life, plastic bags are widely used by people, from vegetable markets to shops, plastic bags are almost everywhere. In order to understand the use of plastic bags and their harm to the environment, I conducted an investigation with Tian.

First, the survey method.

1, went into the vegetable market and made a field survey on the use of plastic bags.

2. Check online to find out the harm of plastic bags to the environment.

Second, market research and data collation

1, time: 9: 00-9: 30 am on May 9, 2009.

2. Survey place: Big Times Vegetable Market; 3. Survey content: the use of plastic bags.

4. Survey results: * * The seven businesses surveyed use about 1.050 plastic bags every day, with an average of about 1.50 plastic bags every day. Two of them are selling vegetables, which cost about 540 a day; Three fruit sellers spend about 290 a day; Two companies selling cooked meat spend about 220 a day.

There are more than 40 people selling vegetables, fruits and cooked meat in the big times vegetable market. About 150× 40 = 6000 plastic bags are used every day, and about 6000× 365 = 2 190000 plastic bags are used every year.

Third, the network data survey

1, survey method: Internet search.

2. Investigation content: the harm of plastic bags to the environment.

3. Investigation results: Plastic bags are not conducive to recycling, and incineration will produce a lot of toxic gases and pollute the atmosphere; Landfill will pollute water and soil, and it will take nearly 200 years to decompose.

Four. conclusion

1. The use of plastic bags in the big times vegetable market is extremely serious. I don't know, but I am shocked. A vegetable market consumes about 2190 thousand plastic bags a year. I dare not count how many vegetable markets there are in China and how many plastic bags are needed.

Plastic bags are very harmful to the environment. The accumulation of waste plastic bags will make mosquitoes and flies multiply and endanger people's health. There are plastic bags in the soil, which will affect the absorption of water and nutrients by crops and inhibit the growth and development of crops. If burned with fire, a large number of toxic gases will appear, polluting the atmosphere and causing immeasurable harm to the environment.

Verb (abbreviation of verb) In view of the above hazards, we make the following suggestions:

1. Carry out publicity in residential areas to publicize the harm of "white pollution" and educate people to care for the environment. 2. Students usually find plastic bags, so they should immediately pick them up and put them in the designated trash can to be an environmental guardian.

Guide residents to use baskets or paper bags instead of disposable plastic bags when shopping. The earth is my home, and protection depends on everyone. Let's work together to protect the global environment and make the world a better place!

Attachment: Environmental Song-How are you, Earth? (Click the "△" in the video with the mouse to start playing. )

April 22nd is Earth Day every year. At present, the world's environmental problems are increasingly prominent, and soil erosion, land desertification and pollution of fresh water resources have seriously affected the life of human society. In addition, with the continuous development of global industry, the excessive emission of carbon dioxide makes the concentration of greenhouse gases in the atmosphere increase continuously, which leads to the destruction of the "protective umbrella" of earth life-the atmospheric ozone layer, and the resulting abnormal global climate change is becoming a worldwide problem that directly threatens human survival. The purpose of holding "Earth Day" is to arouse people's awareness of caring for the earth and protecting their homes, and to promote the coordinated development of resource exploitation and environmental protection. Although there is no unified specific theme for the annual "Earth Day", "There is only one earth" will always be its general theme. In order to better protect the earth. Since the 1990s, China has held the "Earth Day" publicity activity on April 22nd every year, and determined the theme of the activity according to the current situation. In 2008, the theme of "Earth Day" determined by China is the same as the propaganda slogan of "International Year of Earth" in China, that is, "Understanding the Earth and Harmonious Development". Its purpose is to popularize geoscience knowledge to the public, strengthen the understanding and effective utilization of geoscience by the whole society, improve the public's understanding of the national conditions of resources, and realize the harmonious development between man and nature. How are you, Earth (environmental song)
