Multi-purpose of one water
70% of the earth's surface is covered with water, which is about 65.438+0.4 billion cubic meters, of which 96.5% is seawater. Although the rest is fresh water, more than 1/2 of it is ice, and the water resources that can be directly utilized such as rivers and lakes only account for about 0.003% of the total water.
Use detergent carefully.
Detergents are mostly chemical products, and a large amount of wastewater with high detergent content will be discharged into rivers, which will worsen the water quality. Improper use of detergents for a long time will damage people's central system, hinder people's intellectual development, reduce their thinking and analytical abilities, and even cause mental disorders. Detergent residue on clothes will irritate the skin and cause allergic dermatitis. If the detergent with high concentration is used for a long time, carcinogens in the detergent will enter the human body from the skin and mouth, which will damage health.
Don't forget that you are breathing all the time.
The monitoring results of the Global Atmospheric Monitoring Network show that the daily average concentration of total suspended particulate matter in the atmosphere of Beijing, Shenyang, Xi, Shanghai and Guangzhou is 200~500 micrograms per cubic meter, which is 3~9 times higher than the standard of the World Health Organization, and is listed as one of the top ten polluted cities in the world.
Save one degree of electricity and less pollution.
China is a country with thermal power generation as the main energy source and coal as the main energy source. Coal accounts for more than 70% of the disposable energy structure. If it develops in the conventional way, it needs at least 654.38+000 billion tons of coal equivalent energy consumption to reach the level of developed countries, which is equivalent to the sum of global energy consumption. When coal burns, it will release a lot of harmful gases, seriously pollute the atmosphere, form acid rain and cause greenhouse effect.
Power saving
A large number of coal, natural gas and petroleum fuels are used in industry, commerce, housing and transportation. The excessive carbon dioxide produced by burning these fuels is like a glass cover, which blocks the radiation of ground heat to outer space and leaves hot gas in the atmosphere, forming a "greenhouse effect". The "greenhouse effect" leads to global meteorological changes, disastrous droughts and floods, melting icebergs in the Arctic and Antarctic, and rising sea levels. Scientists estimate that if the trend of climate warming continues, low-lying areas such as Bengal, Holland, Egypt, China and some island countries will be in danger of being swallowed up by seawater.
Reduce energy consumption
Fuels such as coal will release carbon and nitrogen oxides in gaseous form when burned. These oxides combine with water vapor in the air to form highly corrosive sulfuric acid and nitric acid, and then fall back to the ground with rain, snow and fog. This is called "death in the air" acid rain. There are three major acid rain areas in the world: the United States and Canada, Northern Europe and South China. Acid rain can not only strongly corrode buildings, but also acidify the soil, leading to the death of trees, crop reduction, acidification of lake water quality and death of fish and shrimp. Due to the extensive use of coal fuel in China, the annual economic loss caused by acid rain pollution is about 20 billion yuan. At present, the acidity of precipitation in acid rain areas in China is still rising and the area is still expanding.
Everyone uses energy-saving lamps.
"China Green Lighting Project" is one of the key points of energy saving in China. Energy-saving and efficient lighting lamps will be popularized throughout the country, which can save coal burning in corresponding power plants and reduce the emissions of sulfur dioxide, nitrogen oxides, dust, ash and carbon dioxide.
Utilize renewable resources
At present, 90% of the energy used by human beings is oil, natural gas and coal. The formation process of these fuels takes hundreds of millions of years and is a non-renewable resource. Solar energy, wind energy, tidal energy and geothermal energy are renewable and are called renewable energy. People call those energy sources that do not pollute the environment "clean energy".
Take pride in taking the bus.
There are nearly1.2000 motor vehicles in Beijing, the capital of China, only 1/6 in Tokyo and new york. However, the concentration of pollutants emitted by each vehicle is 3~ 10 times higher than that of similar foreign vehicles. 73% of hydrocarbons, 63% of carbon monoxide and 37% of nitrogen oxides in Beijing's atmosphere come from motor vehicle emissions. Therefore, citizens are encouraged to travel by bus.
Protecting the atmosphere starts from the first step.
In Europe, in order to reduce air pollution caused by driving, many people are willing to go to work by bike. Such people are respected as environmental defenders. American newspapers often mobilize people to buy as many necessities as possible when shopping in supermarkets to save gasoline and reduce air pollution. The influential American Bicycle Association has been calling on the government to build bicycle lanes when building roads. In Germany, many families like to go out in the same car with their neighbors to reduce the emission of automobile exhaust. In order to purify the urban air, Tehran, the capital of Iran, has stipulated "selfless car day". On this day, the Iranian president also went to work by bus with the citizens. In China and Shanghai, employees of some companies often share a taxi, which is called "fighting".
Reduce tail gas emissions
The Law of People's Republic of China (PRC) on the Prevention and Control of Air Pollution stipulates that motor vehicles and ships shall not discharge pollutants into the atmosphere beyond the prescribed emission standards, and control measures shall be taken for motor vehicles and ships that exceed the prescribed emission standards. Vehicles with pollutant emissions exceeding the national emission standards shall not be manufactured, sold or imported.
Use unleaded gasoline
Cars that use leaded gasoline will emit lead through exhaust gas. After these lead particles enter the human body with breathing, they will cause damage to the human nervous system and accumulate in human bones; If it falls into soil or rivers, it will be absorbed by various animals and plants and enter the human food chain. Lead accumulation in the human body to a certain extent will cause anemia, hepatitis, pneumonia, emphysema, angina pectoris, neurasthenia and other diseases.
Cherish paper
The soaring demand for paper is one of the reasons for the increase in wood consumption. The annual consumption of wood for papermaking in China is100000 cubic meters, including 65438+300000 tons of imported wood pulp and 4 million tons of imported paper. How many trees will be cut down here! The large consumption of paper not only causes the destruction of forests, but also seriously pollutes rivers and lakes because of the sewage discharged from pulp production (the pollution caused by paper industry accounts for more than 30% of the total water pollution).
Use recycled paper
The forest coverage rate in China is only 1/4 of the world average. According to statistics, during the period of 10, the forest in China decreased by 23% and the logging volume decreased by 50%. Since 1950s, the natural forests in Xishuangbanna, Yunnan Province are disappearing at a rate of about 65,438+600,000 hectares per year. At that time, 55% of the original forest area has been reduced 1/2.
Reduce cards to save trees
In recent years, Japanese people with various manners are also changing the habit of giving a large number of New Year cards. Some big companies advertise that they will no longer send greeting cards. Chinese college students organize the activity of "saving cards to save trees" and advocate saving money to buy greeting cards and plant trees to protect nature.
Grain warning line
China has1.300 million hectares of cultivated land, accounting for 7% of the world's cultivated land. The per capita arable land is less than 47% of the world average, and the per capita arable land in more than 600 counties (districts) in the east is below the warning line of 0.05 hectares set by FAO.
Control noise pollution
Noise will interfere with the normal life of residents and damage people's hearing. Noise has obvious influence on human nervous system and cardiovascular system. People who have been exposed to noise for a long time will have symptoms such as headache, brain swelling, palpitation, memory loss and fatigue. Noise can also affect the digestive system, leading to coronary heart disease and arteriosclerosis.
Maintain a peaceful environment
According to German regulations, when using audio equipment indoors, the volume should be clearly audible indoors. American law requires schools to offer noise courses. According to British regulations, audio equipment is not allowed to be used in advertising, entertainment and business activities, and it is not allowed to be used in public places at night. In Japan, it is stipulated to control the noise generated by night operation of catering industry and publicity with audio equipment. Vehicles shall not produce unnecessary noise that affects others, and unnecessary idling of vehicles is prohibited.
Identify "environmental signs"
Environmental protection products certified by China Green Label Certification Committee include low-fluorine household refrigeration appliances, fluorine-free hair gel and styling hair gel, lead-free gasoline, cadmium-free mercury-lead rechargeable battery, phosphorus-free fabric detergent, low-noise washing machine and energy-saving fluorescent lamp. These environmental label products are all marked with "China Environmental Label". The central structure of the logo is green mountains, green waters and the sun, indicating the environment on which human beings depend, and the external 10 ring indicates public participation in environmental protection.
Use fluorine-free products
Chlorine atoms in Freon have a great destructive effect on the ozone layer, which can decompose ozone that absorbs ultraviolet rays and make the ozone layer thinner. Intense ultraviolet radiation will damage the immune function of people and animals, induce skin cancer and cataracts, and destroy the ecosystem on the earth. From 65438 to 0994, the largest ozone hole was observed in Antarctica, covering an area of 2,400 square kilometers. According to relevant data, in southern Chile, which is located on the edge of Antarctic ozone layer, crops are damaged and pasture animals are blind. The ozone layer over the Arctic is also thinning. At present, the first 24 developed countries to use CFCs have signed the Montreal Protocol to restrict the use of CFCs, and the amendment 1990 sets the time for developed countries to ban the use of CFCs in 2000. 1993 in February, the China municipal government approved the China ozone-depleting substances elimination program, and decided to completely eliminate ozone-depleting substances in 20 10.
Choose phosphorus-free washing powder
Most washing powders produced in China contain phosphorus. The annual output of washing powder in China is 2 million tons. According to the average phosphorus content 15%, more than 70 thousand tons of phosphorus are discharged into surface water every year, which has a great impact on rivers and lakes. According to the investigation, the total phosphorus levels in Dianchi Lake, Erhai Lake and Xuanwu Lake are quite high, and the phosphorus brought by washing powder in Kunming domestic sewage exceeds 50% of the total phosphorus load. After a large amount of phosphorus-containing sewage enters the water body, algae will grow wildly in the water body, make the water body eutrophic, reduce the oxygen content in the water, and die of hypoxia. Therefore, water has become stagnant water and smelly water.
Buy environmentally friendly batteries
The batteries we use every day rely on chemical action, also known as corrosion, to generate electricity. Moreover, its corrosion contains a lot of heavy metal pollutants-cadmium, mercury, manganese and so on. When it is abandoned in nature, these toxic substances slowly overflow from the battery, enter the soil or water source, and then enter the human food chain through crops. These toxic substances will accumulate in the human body for a long time, which is difficult to eliminate, damaging the nervous system, hematopoietic function, kidneys and bones, and some will cause cancer. Batteries can be said to be scrapped as much as they are produced; Centralized production and decentralized pollution; Short-term use, long-term pollution
Choose green packaging
Ecological Environment The annual output of garbage in Beijing is 4.3 million tons, and the daily output of garbage is10.2 million tons. On average, each person throws out about 1 kg of garbage every day, which is equivalent to piling up two Jingshan mountains every year. At present, China's garbage output is four times that of 1989, and a large part of it is caused by over-packaging. The packaging cost of many commodities, especially cosmetics and health products, has accounted for 30%~50% of the cost. Overpackaging not only causes great waste, but also increases the economic burden of consumers. At the same time, it also increases the amount of garbage and pollutes the environment.
Identify green food
At present, there are more than 300 green food production enterprises in China, and there are more than 700 kinds of green food developed and produced according to green food standards. Products involved in various food categories, such as beverages, alcohol, fruits, dairy products, cereals and aquaculture. Other green foods, such as whole wheat bread, fresh whole grains, beans and mushrooms, are also very beneficial to human health.
