The more political proposals in junior middle schools (such as those on protecting the environment and saving resources), the better. ...

I. Prevention of air pollution

1, the construction site garbage residue in a timely manner to clean up the scene. When high-rise buildings and multi-storey buildings clean up construction waste, they must set up closed special garbage passages, use containers for lifting or use permanent garbage passages for removal, and it is strictly forbidden to throw them into the air at will.

2. The construction road adopts graded sand or concrete pavement, combined with permanent road layout, and regularly sprinkles water for cleaning to prevent road dust.

3, bagged cement, lime, fly ash and other fine-grained materials, should be stored in the warehouse. When stored outdoors, you must cover it to prevent dust. Bulk cement, lime and fly ash fine particle materials should be stored in fixed containers. If there is no fixed container, it should be stored in a closed special warehouse, and reliable dustproof measures should be taken. Transport fine-grained materials such as cement, lime and fly ash, and take covering measures to prevent scattering and dust along the way. When unloading, take measures to reduce dust.

4, vehicles without muck field measures. Spread a section of gravel at the gate, screen and clean it regularly, and make a ditch to wash the wheels; Manually pat the soil, clean the wheels and help the car; Digging and loading are not overloaded. Pay attention to close the door after unloading, and arrange people to clean and sprinkle water outside the site to avoid scattering soil or dust.

5, it is strictly prohibited to burn linoleum, rubber, leather, leaves, hay and other substances that will produce toxic and harmful smoke and malodorous gases.

6. Motor vehicles should be equipped with PVC valves, and vehicles with excessive exhaust emissions should be equipped with purification silencers to ensure no smoke.

7, site tea stove goods, boilers as far as possible to use smoke and dust removal type, smoke and dust reduced to allow emissions.

8. The common mixing station should be adopted at the site, and the mixing station should be sealed first to avoid dust leakage.

9, demolition of old buildings, should be appropriate sprinkler, to prevent dust.

Second, prevent water pollution.

1. It is forbidden to backfill toxic and harmful wastes with earthwork.

2. The wastewater from the mixing station on the construction site and the wastewater from the terrazzo on the site are discharged into urban sewage pipes or rivers after precipitation.

3. When the oil is stored at the site, the warehouse must be impervious. Measures should be taken to prevent oil from escaping, leaking, dripping and polluting the water body.

4. A grease trap shall be set for sewage discharge in the canteen, and oil and sundries shall be removed regularly to prevent pollution.

5. Anti-seepage measures shall be taken for temporary toilets and septic tanks on the construction site, and flushing toilets shall be adopted in the central city to disinfect, kill flies and mosquitoes regularly.

6. Chemicals and additives should be properly kept and stored in the warehouse.

Third, prevent noise pollution.

1, in densely populated areas, the operation time must be strictly controlled. Under special circumstances, if construction must be carried out around the clock, it must coordinate with the construction unit and the local neighborhood Committee to obtain understanding.

2, strictly control the man-made noise, enter the construction site shall not be loud, without knocking on the template, etc. , restrict the use of loudspeakers.

3. Try to choose low-noise mechanical equipment and technology to reduce noise.

Fourth, protect trees.

1. Apply lime at the bottom of the trunk near the ground about 1 m to prevent pests from climbing along the trunk and damaging trees;

2. Build nests in trees to attract birds to prevent pests;

3. In addition to man-made logging, fire damage to trees is also very great, and it takes a long time to recover itself;

I remember reading a book that it is best to mix tall trees and shrubs. Because shrubs are an excellent place for birds to live, if shrubs are cut down just for beauty, trees will be destroyed by insects as soon as birds leave.

Best answer

Sinful human beings:

Although today's developed earth environment looks optimistic, there are very serious hidden dangers, which are all man-made: cutting down trees at will, setting up chemical plants, and discharging harmful liquids at will. "The annual emissions of gases that pose a greater threat to mankind in the world exceed 600 million tons ...; It is estimated that by the middle of the next century, one third of the earth's surface will be in danger of desertification, and 6 square kilometers of land will be desertification every year, threatening more than 60 countries ... "What do people think of these shocking figures? From 23 million years ago to the appearance of forest apes180 thousand years ago, and then to the highly developed civilization era of human beings, nature has always been "responsive" to everyone, which has further bred human greed.

For example, the Mulan River in China was originally a crystal clear river in the early 1950s, but now it has become a polluted river, and fish and shrimps have disappeared, adding another scar to our mother earth. Isn't this a wake-up call for mankind?

Therefore, I solemnly suggest to people who haven't realized it:

First, if human beings want to conquer the terrible nature, they must respect it. We should not only be cautious about transforming nature, but also boldly practice and improve it, so as to control nature and make our own interests develop harmoniously with nature. We must never repeat the mistake of "polluting first, then managing" in western developed countries.

Second, starting from me, first choose a lifestyle that is conducive to protecting the environment. Be kind to our home and the earth and create a beautiful living environment.

1, saving resources and reducing pollution.

(1) Be proud of saving water. Turn off the tap at any time to prevent dripping.

(2) Use detergent carefully and use soap as much as possible to reduce the pollution of chemicals in detergent to water quality.

2. Green consumption and environmental protection choice

(1) Use unleaded gasoline, cadmium-free lead batteries and phosphorus-free detergents to reduce water and air pollution.

(2) Buy low-priced household refrigeration appliances and mousse that doesn't hurt hair, so as to reduce the pollution to the ozone layer.

3. Repeated use for many times

Try to use disposable goods less and use durable goods more. If disposable plastics and lunch boxes are not used, white pollution will be reduced; Do not use disposable chopsticks; Bring your own shopping bag or basket.

4. Classified recovery and reuse

Do not throw waste batteries, waste plastics and other garbage and waste; Classify garbage, turn waste into treasure, recycle resources and benefit mankind.

5. Protect the existence of all things in nature.

Do not hunt and use rare animals and protect animals, and cherish and protect wild animals and plants; Afforestation, care for every inch of green space, every flower and every tree around you.

6. Pay attention to hygiene and protect the environment

No spitting, no littering, no smoking and no noise in public places.

As a primary school student in the new era, I advocate students to improve their awareness of environmental protection, and also suggest that uncles and aunts join our team to contribute to environmental protection and benefit future generations. Because: protecting the environment is urgent.

Environmental protection suggestions

In the new century, we are eager for a clean earth, a healthy earth, an environmentally friendly home, and a green, healthy and hygienic community to blossom everywhere ... grandparents, uncles and aunts, let's act at once! In order to protect the green of the earth, for future generations, eliminate pollution and protect the development environment. Here, we launched an initiative:

1, using phosphorus-free detergent. When using phosphorus-containing detergent, a large amount of phosphorus will enter the urban water body, causing the water quality to decline and the water body to turn black and stink. We can choose "phosphorus-free" detergent to reduce pollution.

Please turn off the faucet at hand and advocate multi-purpose of one water. A faucet that can't be turned off tightly can drain 1-6 tons of water a month. It's easy to turn off the tap conveniently, and multi-use of one water is the concrete embodiment of saving water.

Please classify and recycle the renewable resources, and pay attention to recycling the waste plastic products in time.

Please use less disposable products. Disposable products bring us convenience, but also waste a lot of valuable resources. "disposable" items, we really can't afford to consume!

5. Please choose environmentally friendly building materials to decorate the living room. Many people will feel headache and nausea after living in the newly renovated house, which is caused by the pollution produced during the decoration process. (If materials containing benzene and other harmful substances exceed the standard are used) Therefore, I would like to remind everyone to use environmentally friendly materials as much as possible when decorating.

6. Refuse to use wildlife products. If you don't wear rare animal fur clothing, try to wear natural fabrics; Refuse to eat wild animals; Traveling in the wild, not poaching wild animals and so on.

7. Promote the purchase of green food.

We believe that one day, green environmental protection will shine intoxicating starlight in every corner of us.
