Save resources and reduce pollution

Human beings only have one earth. The earth is facing an ecological crisis. As long as we change our wasteful and polluting lifestyle, we can improve the environment and reduce the burden on the earth. Uncontrolled consumption of the earth's resources will make human existence unsustainable.

No matter what profession you are engaged in, you have the responsibility to advocate and implement a resource-saving lifestyle; no matter how rich you are, you have no right to squander the earth's resources, because the earth is borrowed from future generations. The economic scale of contemporary people simply cannot reflect the true value of ecological and environmental resources.

Thrifting is not just an economic behavior here, but also an environmentally friendly fashion. You will be respected for caring about the planet and caring about the future. Spending is no longer about dignity and glory, but selfishness and indifference, because you are willing to destroy the foundation of survival for future generations for your own enjoyment.

Start with "Reduce" - save resources and reduce pollution, and start your green life!

1. Take pride in saving water and turn off the faucet at any time, don’t let the water flow empty

Our country is one of the 12 water-poor countries in the world, and its freshwater resources are less than the world’s per capita water supply. 1/4. More than half of the country's more than 600 cities are short of water, and 108 of them are seriously short of water. The scarcity of surface water resources has led to excessive exploitation of groundwater. In the 1950s, wells in Beijing could produce water about 5 meters below the surface. Now the average depth of 40,000 wells in Beijing is 49 meters, and groundwater resources are nearly exhausted.

2. Use water for multiple purposes and reuse water

70% of the earth’s surface is covered by water, with about 1.4 billion cubic meters of water, 96.5% of which is seawater. Although the rest is fresh water, more than half of it is directly usable water resources such as ice, rivers and lakes, accounting for only about 0.003% of the entire water volume.

3. Stop dripping, check and repair faucets

The "Law of the People's Republic of China on the Prevention and Control of Water Pollution" stipulates: All units and individuals have the responsibility to protect water resources and have the right to Supervise and report behaviors that pollute and harm the water environment.

4. Guard water sources. Protecting water sources means protecting life.

According to environmental monitoring, about 100 million tons of sewage are discharged directly into water bodies across the country every day. The water quality of more than half of the seven major river systems in the country is polluted. Among the 35 key lakes, 17 are seriously polluted, and one-third of the country's water bodies are not suitable for irrigation. More than 90% of urban waters are seriously polluted, more than 50% of urban water sources do not meet drinking water standards, and 40% of water sources are no longer drinkable. 60%-70% of the total water shortage in southern cities is caused by water source pollution.

5. Use detergents with caution and use soap as much as possible to reduce water pollution

Most detergents are chemical products. When wastewater with high detergent content is discharged into rivers in large quantities, it will cause Water quality deteriorates. Improper use of detergents for a long time will damage the central system of people, hinder their intellectual development, reduce their thinking and analysis abilities, and even cause mental disorders in severe cases. Remaining detergents on clothes can irritate the skin and cause allergic dermatitis. If detergents with higher concentrations are used for a long time, the carcinogens in the detergents will enter the human body from the skin and mouth, harming health.

6. When caring about air quality, don’t forget that you are breathing all the time

The monitoring results of the Global Atmosphere Monitoring Network show that the five cities of Beijing, Shenyang, Xi’an, Shanghai and Guangzhou have The daily average concentration of total suspended particulate matter in the atmosphere is 200-500 micrograms per cubic meter, 3-9 times higher than the World Health Organization standard, and it is listed among the top ten most polluted cities in the world.

7. Turn off the lights to save electricity and reduce pollution.

my country is a country dominated by thermal power generation and coal as the main energy source. Coal accounts for more than 70% of the primary energy structure. If developed in a conventional way, reaching the level of developed countries will require at least 10 billion tons of coal-equivalent energy consumption, which will be equivalent to the total global energy consumption. When coal is burned, it will release a large amount of harmful gases and seriously pollute the atmosphere. And form acid rain and cause the greenhouse effect.

8. Energy-saving appliances contribute to slowing global warming

A large amount of coal, natural gas and petroleum fuels are used in industry, commerce, housing and transportation. These fuels The excess carbon dioxide produced during combustion acts like a glass cover, blocking the heat from the ground from radiating to outer space, trapping heat in the atmosphere, forming a "greenhouse effect". The "greenhouse effect" causes global climate variability, causing catastrophic droughts and floods. , causing icebergs in the Arctic and Antarctic to melt, causing sea levels to rise. Scientists estimate that if the trend of climate warming continues, lower-altitude places such as Bangladesh, the Netherlands, Egypt, low-lying deltas in China, and several island countries will be in danger of being engulfed by seawater.

9. Turn on less air conditioning to reduce energy consumption

When coal and other fuels are burned, carbon and nitrogen oxides are emitted in the form of gases. These oxides combine with water vapor in the air. Highly corrosive sulfuric acid and nitric acid are formed, and then fall back to the ground together with rain, snow, and fog. This is acid rain known as the "airborne death". There are three major acid rain regions in the world: the United States and Canada, the Nordic region, and southern China. Acid rain can not only strongly corrode buildings, but also acidify the soil, causing trees to die, crop yields to decrease, lake water quality to become acidic, and fish and shrimp to die. Due to the extensive use of coal fuel in our country, economic losses caused by acid rain pollution amount to about 20 billion yuan every year. The acidity of precipitation in acid rain areas in my country is still increasing and the area is still expanding.

10. Support green lighting and everyone should use energy-saving lamps

The "China Green Lighting Project" is one of the key points of energy conservation in our country. According to the project implementation plan, energy-saving and efficient lighting fixtures will be promoted throughout the country during the "Ninth Five-Year Plan" period. By the year 2000, we will strive to save 22 billion kilowatt-hours of lighting electricity, save coal in corresponding power plants, and reduce emissions of sulfur dioxide, nitrogen oxides, dust, ash and carbon dioxide.

11. Use renewable resources and don’t wait until the day when energy is exhausted

90% of the energy currently used by humans 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 sources. People call energy that does not pollute the environment "clean energy".

12. Be a "bus person" and take pride in taking public transportation

There are nearly 1.2 million motor vehicles in Beijing, the capital of our country, which is only the number of motor vehicles in cities such as Tokyo and New York. 1/6 of the total number of motor vehicles. However, the concentration of pollutants emitted by each vehicle is 3-10 times higher than similar foreign motor vehicles. 73% of hydrocarbons, 63% of carbon monoxide, and 37% of nitrogen oxides in Beijing's atmosphere come from vehicle emissions.

13. When "Bicycle Heroes" Protecting the atmosphere starts with a single step

In Europe, many people are willing to ride bicycles to work in order to reduce the air pollution caused by driving. Such people Be respected as a champion of the environment. American newspapers often mobilize people to buy as many necessities as possible when going to supermarkets and reduce the number of trips to supermarkets in order to save gasoline and reduce air pollution. The influential American Bicyclists Association has been calling on the government to build bike lanes when building roads. In Germany, many families like to go out in the same car as their neighbors to reduce vehicle exhaust emissions. In order to clean the city's air, Tehran, the capital of Iran, has designated a "Car-Free Day". On this day, the President of Iran also takes a bus to work with citizens. In Shanghai, my country, some company employees often share a taxi called "fighting".

14. Responsibilities of drivers to reduce exhaust emissions

The "Law of the People's Republic of China on the Prevention and Control of Air Pollution" stipulates: Motor vehicles and ships shall not emit pollutants into the atmosphere exceeding the prescribed limit. Emission standards: Control measures must be taken for motor vehicles and ships that exceed the prescribed emission standards. Cars whose pollutant emissions exceed the national emission standards must not be manufactured, sold or imported.

15. Driver’s choice when using unleaded gasoline

Cars using leaded gasoline will emit lead through the exhaust. After these lead particles enter the human body through breathing, they will damage the human nervous system and accumulate in human bones. If they fall into the soil or rivers, they will be absorbed by various animals and plants and enter the human food chain. When lead accumulates in the human body to a certain extent, people will suffer from anemia, hepatitis, pneumonia, emphysema, angina, neurasthenia and other diseases.

16. Cherishing paper means cherishing forests and rivers

The surge in demand for paper is one of the reasons for the growth in wood consumption. The country’s annual paper production consumes 10 million cubic meters of wood, and imported wood More than 1.3 million tons of pulp and more than 4 million tons of paper are imported. How many trees will be cut down? The massive consumption of paper not only causes forest destruction, but also severely pollutes rivers and lakes due to the discharge of sewage from pulp production (the pollution caused by the paper industry accounts for more than 30% of the entire water pollution).

17. Use recycled paper to reduce deforestation

my country’s forest coverage rate is only 1/4 of the world average. According to statistics, my country's forests have dropped sharply by 23% in 10 years, and the harvestable stock volume has decreased by 50%. The natural forests in Xishuangbanna, Yunnan, have been disappearing at a rate of about 16,000 hectares every year since the 1950s. The original forest cover of 55% at that time has now been reduced by half.

18. Replace New Year's cards to reduce the burden on the earth

The Japanese, who have a lot of etiquette, have also changed their habit of giving a large number of New Year's cards in recent years. Some large companies have advertised that they will no longer send greetings by mailing New Year's cards. College students in my country organized the "Reduce Cards to Save Trees" campaign, advocating saving money on greeting cards to plant trees and protect nature.

19. The new fashion of food saving turns frugality into glory

my country has more than 130 million hectares of arable land, accounting for 7% of the world's arable land. The per capita cultivated land is less than 47% of the world average, and the per capita cultivated land in more than 600 counties (districts) in the east is lower than the warning line of 0.05 hectares set by the Food and Agriculture Organization of the United Nations.

20. Control noise. Pollution allows us to supervise each other.

Noise will interfere with the normal life of residents and cause damage to people's hearing. Noise has a significant impact on the human nervous system and cardiovascular system. People who are exposed to noise for a long time will develop symptoms such as headache, brain swelling, palpitation, memory loss and fatigue. Low-frequency noise makes people feel chest tight and nauseated. Noise can also affect the digestive system and can lead to coronary heart disease and arteriosclerosis.

21. To maintain a peaceful environment, let us start from ourselves

Germany stipulates that when using audio equipment indoors, the volume must be audible indoors. American law stipulates that noise should be set in schools. courses. British regulations prohibit the use of audio equipment in advertising, entertainment and commercial activities, and audio equipment must not be used in public places at night. Japan stipulates that the noise generated by night operations in the catering industry and the noise generated by the use of audio equipment for publicity is limited to limits; vehicles must not produce unnecessary noise that affects others, and unnecessary idling of cars is prohibited.
