Environmental protection tips. Slogans. Stories, hurry, hurry! ! !

, (1) Global warming refers to the increase in global temperature. In the past 100 years, the global average temperature has experienced two fluctuations: cold-warm-cold-warm, which can always be seen as an upward trend. After entering the 1980s, global temperatures have increased significantly. From 1981 to 1990, the global average temperature increased by 0.48°C compared with 100 years ago. The main cause of global warming is mankind's extensive use of fossil fuels (such as coal, oil, etc.) over the past century, which has emitted large amounts of CO2 and other greenhouse gases. Because these greenhouse gases are highly permeable to short-wave radiation from the sun, and highly absorbent to long-wave radiation reflected from the earth, which is often called the greenhouse effect, it leads to global climate warming. Global warming The consequences will be redistribution of global precipitation, melting of glaciers and permafrost, and rising sea levels, which will not only endanger the balance of natural ecosystems, but also threaten human food supply and living environment.

2) Destruction of the ozone layer. There is an ozone layer in the stratosphere about 20 to 30 kilometers near the ground. The ozone content accounts for one hundred thousandth of the total gas at this altitude. Although the ozone content is extremely small, it has a strong ability to absorb ultraviolet rays. , therefore, it can block the damage caused by the sun's ultraviolet radiation to the earth's organisms and protect all life on the earth. However, some pollutants are emitted from human production and life, such as chlorofluorocarbons and other refrigerants in refrigerators and air conditioners. Compounds such as fluorobromohydrocarbons are used. They can be inflamed after being irradiated by ultraviolet rays, forming highly active atoms that interact with ozone (O3) in the ozone layer, turning them into oxygen molecules (O2). This interaction occurs in a chain-like manner. The ozone layer in Antarctica is depleted rapidly and the ozone layer is destroyed. By 1994, the area of ??ozone layer destruction in Antarctica had reached 24 million square kilometers. It was formed over 2 billion years, but was destroyed by 60% in just one century. The ozone layer over the Northern Hemisphere is also thinner than ever before. The ozone layer over Europe and North America has decreased by 10 to 15% on average, and it has even decreased over Siberia. 35%. Therefore, scientists warn that the degree of destruction of the ozone layer above the earth is much more serious than most people imagine.

(3) Acid rain Acid rain is caused by sulfur dioxide (SO2) and nitrogen oxides (nitrogen oxides) in the air. Acidic precipitation with a pH value less than 5.6 caused by acidic pollutants such as NOx) has caused acidification of soil and lakes in areas affected by acid rain, damage to vegetation and ecosystems, and corrosion of building materials, metal structures, and cultural relics. environmental problems. Acid rain first appeared in Northern Europe and Central Europe in the 1950s and 1960s. At that time, acid rain in Northern Europe was caused by the migration of acidic waste gases from industries in central Europe. Since the 1970s, many industrialized countries have taken various measures to prevent and control the atmosphere in cities and industries. Pollution, one of the important measures is to increase the height of the chimney. Although this measure effectively changes the quality of the atmospheric environment in the emission area, the problem of long-distance migration of air pollutants is more serious. The pollutants cross national boundaries and enter neighboring countries, and even Floating long distances, it creates a wider range of transnational acid rain. In addition, the use of fossil fuels around the world has continued to increase, which has further expanded the areas affected by acid rain. Europe, North America and East Asia are seriously affected by acid rain. region.

In my country, acid rain mainly occurred in the southwest region. By the mid-1990s, it had spread to the south of the Yangtze River, east of the Qinghai-Tibet Plateau and the Sichuan Basin.

Two, 1. Turn off the faucet

When washing hands and applying soap, turn off the faucet. Do not wash dishes or wash clothes with the faucet running. If you see a leaking faucet, be sure to tighten it.

2. Use one water for multiple purposes

Use secondary water as much as possible. For example, the water used for washing rice or washing vegetables can be used to water flowers; the water used for washing faces and laundry can be retained for wiping floors and flushing toilets. Shower often, bathing saves water and is more hygienic.

3. Put a Coke bottle in the toilet tank.

If your flush toilet has a large capacity, you can put a Coke bottle filled with water in the water tank. This small action of yours can save 1.25 liters of water each time.

4. Use less detergent.

Most detergents are chemical products and will pollute water sources. If there is too much grease when washing dishes, you can pour out the remaining grease first, and then wash it with hot noodle soup or hot soapy water, so that too much grease will not be discharged into the waterway.

Kitchen utensils with heavy oil stains can also be cleaned with soda and hot water.

5. Do not leave the TV in standby mode for a long time

Standby mode means that it is only turned off by remote control, but the power is not actually completely cut off. Each color TV consumes about 1.2 watts/hour in standby mode.

6. Use warm water to cook rice

Using warm water to cook rice can save 30% of electricity. The inner pot and electric hot plate of the rice cooker should be cleaned in time. Unplug the rice cooker immediately after use, which can save energy and extend its service life.

7. Strive to become a public transportation person or a bicycle person

Use more public transportation such as buses, subways, and trams, which can not only save gasoline but also reduce vehicle exhaust emissions. It can also reduce air pollution and alleviate traffic congestion. People with private cars should try to use unleaded gasoline because lead can seriously damage people's health and intelligence.

Environmentally friendly shopping, turning banknotes into votes

If we can check whether it is marked with the "China Environmental Label" before purchasing a product, the banknotes in our hands will become It has become a "green vote" - if a product meets environmental protection requirements, we will buy it and let it occupy an increasing share in the market; if a product does not meet environmental protection requirements, we will not buy it. At the same time, it also mobilizes others not to buy it, so that it will be gradually eliminated or forced to convert into green food that meets environmental protection requirements.

8 Buy green food

Many vegetables and fruits have been sprayed with pesticides and chemical fertilizers, and many foods use additives. Such food is harmful to health and intelligence. Therefore, it is necessary to buy fresh fruits and vegetables that do not use pesticides and chemical fertilizers, and eat less convenient fast food containing preservatives, drinks with pigments, and crispy snacks with additives. Or you can look for the “green food” sign when purchasing food.

9. Choose phosphorus-free laundry detergent

When phosphorus-containing laundry detergent enters the water source, it will cause algae to grow wildly in the water, the oxygen content in the water will decrease, and aquatic organisms will die due to lack of oxygen. The water body has thus become stagnant and smelly water.

10. Buy rechargeable batteries

The batteries we use every day rely on chemical action, or, in layman’s terms, corrosion to produce electrical energy. When they are abandoned in nature, these substances slowly overflow from the battery, enter the soil or water sources, and then enter the human food chain through crops. After the used dry batteries reach 30 kilograms, you can contact the local garbage recycling center for recycling.

11. Refuse excessive packaging

The packaging fees of many products such as cosmetics and health care products have accounted for 30% to 50% of the cost. Excessive packaging increases the economic burden on consumers, increases the amount of garbage, and pollutes the environment.

12. Bring your own vegetable basket to buy groceries

Reduce the use of plastic shopping bags when shopping, and bring cloth bags or vegetable baskets with you when shopping.

13. Use less disposable tableware

When eating out, bring your own chopsticks and spoons. Use less fast food boxes, paper cups, paper plates, etc., and especially use chopsticks less often. Disposable chopsticks were invented by the Japanese. Japan's forest coverage rate is as high as 65%, but their disposable chopsticks are all imported. my country's forest coverage rate is less than 14%, but it is a big country exporting disposable chopsticks.

14. Use less wooden pencils and more mechanical pencils.

Some developed countries have regarded the manufacturing of wooden pencils as a "sunset industry" and have begun to only produce automatic pencils.

15. Make full use of white paper and try to use recycled paper

The paper that has been used on one side can be turned over to make scratch paper and note paper. Refuse to accept those propaganda materials that are distributed everywhere. The production of these propaganda materials will not only waste a lot of paper, but also destroy the city appearance and hygiene by distributing and posting them everywhere. Recycled paper is produced from recycled waste paper. One ton of waste paper = 800 kilograms of recycled paper = 17 big trees.

The use of recycled paper has become fashionable in many countries, and people take it as an honor to produce slogans printed with "Made from Recycled Paper" to show their environmental awareness and civilized upbringing.

Classification and recycling, regaining the old tradition of waste recycling

“Recycling” is not unfamiliar to us. I remember when I was a child, I could save three toothpaste peels and exchange them for a piece of sugar cake; dried orange peels could be sold to pharmacies; waste cloth scraps, waste ink bottles, etc. could all be reused. Not only does garbage not cause environmental disasters, it also provides raw materials for society. Now, we all regard mixing garbage as a habit.

You must know that mixed garbage treats garbage as waste, while garbage packaging treats garbage as resources; mixed garbage is sent to landfills, occupying a large amount of land, and separated garbage It is distributed to various recycling departments and does not occupy land; whether mixed garbage is landfilled or incinerated, it will pollute the land and atmosphere, while separate garbage will promote harmless treatment; mixed garbage increases the work of sanitation and environmental protection departments , sorting garbage only requires a little effort from us.

16. Set up three classified garbage baskets at home

Household garbage can usually be divided into: 1. Recyclables, including waste paper, waste plastic, waste glass, scrap metal, etc. ; 2. Non-recyclable materials, including kitchen residues such as dust, vegetable leaves, melon and fruit peels and cores; 3. Hazardous materials, including batteries and fluorescent lamps. By setting up three garbage baskets at home, you can separate the garbage while generating it.

17. Sell waste plastic waste, waste paper, waste glass, and metal once a month

Many waste plastics can be reduced to recycled plastics, and all waste lunch boxes and food bags , textile bags, flexible packaging boxes, etc. can all be recycled into fuel.

1 ton of waste plastic = 600 kilograms of gasoline

Each piece of paper can be recycled at least twice. After the first recycling of office paper, old letter paper, notebooks, books, newspapers, advertising paper, cartons, paper tableware, etc., the paper can be recycled into books, manuscript paper, business cards, note paper, etc. After the second recycling, it can also be made into toilet paper.

Remaking aluminum from aluminum cans consumes 71% less energy than extracting aluminum from bauxite; the energy saved by recycling a glass bottle can make a light bulb shine for 4 hours.

18. Exchange, donate, and transform redundant items

You may have some useless things at home that are a pity to throw away. Have you ever thought about exchanging and donating them? So that it can be reused by someone else?

Many old things can be reused. You might as well try to turn some originally useless things into useful household furnishings and supplies. For example, use white foam plastic to make photo frames, use cloth or outdated clothes to collage bedspreads or wall hangings, use plastic juice bottles to make various decorations, and use waste paper to make postcards, New Year's cards, etc. With just a little thought, you can turn many useless things into your own creations, which are both leisurely and environmentally friendly, killing two birds with one stone.

To protect nature is to protect ourselves

On the earth, humans are not the only animals, there are many other creatures. Like humans, they are all citizens of nature. The extinction of any species will affect the balance of the entire biological chain. To protect biological diversity is to protect the species itself. Let us build a nature reserve in everyone's heart.

19. Refuse to eat wild animals and refuse to use wild animal products

Do not eat in restaurants that eat wild animals. Do not wear rare animal fur clothing, and do not use wild animal and plant products, such as ivory, tiger bones, mahogany furniture, etc.

20. Adopt a tree or be an environmental volunteer for a day

Participate in tree adoption activities, hang a small sign on the tree, write your name on it, and water it regularly Water, cultivate the soil, take care of it to grow, and let it become a member of your family.

A 50-year-old tree produces oxygen worth about 250,000 yuan; absorbs toxic gases and prevents air pollution is worth about 500,000 yuan; increases soil fertility is worth about 250,000 yuan; and conserves water sources is worth 35 Ten thousand yuan; providing a breeding place for birds and other animals is worth about 250,000 yuan; and producing protein is worth 20,000 yuan. Excluding the value of flowers, fruits and wood, the total value is approximately 1.5 million yuan.

How to reduce the impact of television on health?

The flame retardant material in the TV will fission at high temperatures, thus producing brominated dioxin, which is harmful to human health. So what should we pay attention to when watching TV?

When watching TV, it is best to ventilate for 10 minutes every hour to effectively reduce the concentration of respirable particulate matter and bromodioin in the room. In addition, do not eat while watching TV, because bromodiamine has a strong adsorption ability to food.

When watching TV, you should sit directly in front of the TV. The optimal distance is 6-8 times the diagonal of the TV screen. After watching TV, wash exposed skin with warm water.

After the TV has been used for a period of time, it is best to ask professionals to clean it. You can also use a small vacuum cleaner to simply clean the heat dissipation holes.

Opening windows in traffic jams is useless

Traffic jams are common in cities. When encountering traffic jams, many people will roll down their windows to get some air, or turn off the air conditioner and open their windows to save fuel. As everyone knows, it is best not to open the windows when there is a traffic jam.

Experts said that places with serious traffic jams are narrow, crowded, and have poor air circulation, and the content of benzopyrene is high. Benzopyrene is a gas with a special smell. This substance can be produced when burning gasoline, coal or smoking. It not only irritates the respiratory tract, but is also a carcinogen. In addition, due to incomplete combustion in the engine, other harmful substances will be produced in the air, such as benzene, toluene, xylene, suspended particulate matter, etc.

Generally speaking, pollution on main highways and traffic light intersections is very serious. Main roads are prone to form strip-shaped pollution zones. The pollution level is centered on the main road and gradually weakens from the middle to both sides. At traffic light intersections, poisonous gases are released mainly when the engine starts when the light turns green.

In fact, many people who encounter traffic jams open their windows to get some air because they are irritated. At this time, you might as well listen to music or chat to relieve your mood. You can also think about dinner recipes or plan your work for the week, so that you won't find it difficult to be stuck in traffic.

How to remove and reduce air pollution in new cars

With the improvement of people’s living standards, some consumers have bought their beloved new cars, but the air pollution in new cars has also become more and more serious. The more people are worried about it, experts remind car buyers to pay attention:

1. Within six months of driving a new car, do not close the windows tightly while driving, and use the air conditioner as little as possible to enhance ventilation and ventilation in the car. to release harmful substances in the car as soon as possible;

8. If the car owner drives the new car for a while After a while, physical symptoms are discovered, such as feeling smokey in the eyes, respiratory irritation or even dizziness. If the smell cannot be completely dissipated within three months or even six months, the air quality in the car should be tested to detect and eliminate it as soon as possible. Internal pollution sources;

9. Four categories of people should pay special attention to the hazards of pollutants in new cars: people with weak constitutions, women, children and people with allergic constitutions. These people should try to avoid driving and riding for long periods of time. New car. Studies have shown that women are particularly sensitive to the inhalation of benzene and formaldehyde. Especially long-term inhalation of benzene in pregnant women can lead to fetal development abnormalities and miscarriage.
