Greenhouse gases make the earth fever. Over the past 200 years, with the deepening of industrialization, a large number of greenhouse gases, mainly carbon dioxide, have been emitted, resulting in global temperature rise and climate change.
The necessity of choosing low carbon life habits of low carbon life
The necessity of choosing low carbon life
It means lower (lower) greenhouse gas emissions (mainly carbon dioxide). As a way of life, low-carbon life first rose from abroad. It can be understood as: reducing carbon dioxide emissions is a way of life with low energy, low consumption and low expenditure. Nowadays, this trend is gradually rising in some big cities in China, which has imperceptibly changed people's lives. Low carbon life represents a healthier, more natural and safer way to carry out the activities between man and nature. Some people advocate to change the details of life from the three links of energy saving and recycling, so as to be as close to low-carbon life as possible.
Nowadays, this way of life has quietly entered China. Many low-carbon websites have begun to popular a kind of special calculator for calculating individual carbon emissions. For example, the low-carbon calculator of China City low-carbon economy network can not only calculate the carbon emissions of daily life, but also show different lifestyle, housing structure and new technology on carbon The impact of emissions.
For ordinary people, it is a kind of attitude towards life, and at the same time, it has become a new way for people to promote the trend. We should pay attention to the low-carbon solar term and put forward the problem of low-carbon in our life. Start with these little things. In addition to planting trees, there are also people who buy goods with short transportation mileage. Some people insist on climbing stairs. Some of them are very interesting, others are not immune to some troubles. Low carbon life can be understood as: reducing carbon dioxide emissions is a life of low energy, low consumption and low expenditure. But the premise is to do its best to save energy and reduce emissions without reducing the quality of life. Energy saving and emission reduction is not only a buzzword in today's society, but also a strategic choice related to the future of mankind. It is of great significance to improve the awareness of energy conservation and emission reduction, to make simple and easy changes to their own lifestyle or consumption habits, and to reduce global greenhouse gas (mainly carbon dioxide) emissions. Low carbon life, energy conservation and environmental protection, is conducive to slowing down the global warming and environmental degradation. Reducing carbon dioxide emissions and choosing a low-carbon life is the responsibility of every citizen, and it is also the obligation of every citizen.
The harm of greenhouse gases
Greenhouse gases make the earth fever. Over the past 200 years, with the deepening of industrialization, a large number of greenhouse gases, mainly carbon dioxide, have led to global temperature rise and climate change, which is an indisputable fact. The 2009 global climate report released by the World Meteorological Organization (WMO) on December 8 pointed out that the past 10 years have been the hottest in the world on record. In addition, global warming also makes Antarctic glaciers begin to melt, resulting in sea level rise. According to the latest survey released by Finnish and German scholars, sea level may rise by 1-9 meters by the end of this century, far exceeding previous expectations. If this continues, Tuvalu, an island country in the South Pacific, will probably be the first one to disappear in the ocean.
A study published by American media on December 5, 2009 pointed out that the earth's fever has also caused a great crisis to human health.
First, allergy aggravation. Studies have shown that with the gradual increase of carbon dioxide level and temperature, the flowering period comes ahead of time, which increases pollen production and aggravates allergy in spring.
Second: species are becoming smaller and smaller as global temperatures rise, as evidenced by Scottish sheep.
Third, kidney stones are increasing. Due to the increase of temperature and dehydration, researchers predict that by 2050, there will be 2.2 million new patients with urinary calculi.
Fourth, the spread of foreign infections, the rise of water environment temperature will make mosquitoes and plankton multiply in large numbers, causing outbreaks of dengue fever, malaria and encephalitis from time to time.
Fifth: the summer temperature rises, the cool wind reduces, will aggravate the ozone pollution, extremely easy to cause the lung infection.
Sixth: algae flooding causes diseases, and the rising water temperature leads to the rapid proliferation of cyanobacteria. From municipal water supply system to natural lakes, pollution will lead to diseases of digestive system, nervous system, liver and skin. Low carbon life has become an urgent way of life for human beings.
Carbon dioxide can aggravate the greenhouse effect, so it is one of the air pollutants. However, under normal conditions, the concentration of carbon dioxide is not reported in the air quality forecast. In addition, when the concentration of carbon dioxide in the air exceeds 50%, it will cause asphyxia. Therefore, it is necessary to avoid going to places with high concentration of carbon dioxide (such as the cellar where vegetables are stored). Ventilation should be conducted before going to these places.
Habits of low carbon life
1. The daily rice washing water can be used to wash hands, wash faces, wash off oily tableware, clean furniture, water flowers, etc. Clean and healthy, natural moisture;
2. It can not only absorb the moisture, but also absorb the peculiar smell in the wardrobe; it can also wipe the glass, reduce the use of environmental glass cleaner;
3, do not throw away the mask paper, use it to wipe the jewelry, wipe the surface of the furniture or wipe the belt, not only rub bright, but also leave the fragrance of mask paper.
4. After drinking tea residue, dry it in the sun to make a tea pillow, which is not only comfortable, but also can help improve sleep; it can also be used for washing dishes, raw materials for Hand-made Soap, and can absorb peculiar smell after drying;
5. Go shopping, try to bring your own environmental protection bags, whether it is free or charged plastic bags, reduce the use of protection of the earth - low carbon life.
6. Bring your own drinking cup when you go out, reduce the use of disposable cup.
7. Use permanent chopsticks and lunch boxes, bring your own tableware as far as possible, and avoid using disposable tableware;
8. Develop the habit of turning off the power supply of electrical appliances at will to avoid wasting electricity.
9. Try not to use refrigerator, air conditioner and electric fan. When hot, you can use fan made of Pu fan or other materials.
10, before opening the air conditioner in summer, the windows should be opened first, so that the indoor air will be changed naturally. The fan can be used to cool the room first, and the air conditioner will be adjusted to room temperature between 25~26 degrees (preferably 26 degrees above).
11. Used plastic bottles can be used to hold various liquid substances (or beans) after washing them.
12. Food waste and residue can be used as fertilizer.
Choose to live a low carbon life
Household electrical equipment
Refrigerator
The amount of food stored in the refrigerator should account for 80% of the volume. If it is too much or too little, it will cost electricity. There should be a gap of more than 10 mm between food and refrigerator. Several plastic boxes are used to hold water. Ice is made in the freezer and then put into the freezer. This can prolong the downtime and reduce the startup time.
air conditioner
The current of the air conditioner is large at the moment of start-up, and the frequent switch of the air conditioner consumes electricity and damages the compressor easily. Put the fan under the internal unit of the air conditioner, and use the wind power of the fan to improve the cooling effect. Turn on the fan immediately after the air conditioner is turned on. In the evening, you don't have to turn on the air conditioner all night, saving nearly 90% of the electricity. Set the air conditioner in dehumidification mode, even if the room temperature is slightly higher, it can also make people feel cool, and save electricity than refrigeration mode.
computer
When the computer is not used for a short time, the energy consumption can be reduced to less than 60% by using the sleep mode of the computer. The unused programs, speakers, printers and other peripheral devices should be turned off. The hard disk, floppy disk and CD-ROM should not work at the same time. The brightness of the display should be appropriately reduced. Special attention should be paid to the use of notebook computer: completely discharge the battery; try not to use external devices; close the devices and interfaces not used temporarily; close the screen saver; select a reasonable shutdown mode: when you need to recover immediately, use standby mode; when using battery, use SpeedStep technology and CPU automatically Frequency reduction, power consumption can be reduced by 40%.
Washing machine
In the same long washing time, when the weak gear works, the motor starts more times. That is to say, using the strong gear can save power than the weak gear, and can prolong the life of the washing machine. The dehydration rate can reach 55% when the speed is 1680 RPM (turbine type only) for 1 minute. Generally, dehydration does not exceed 3 minutes. It is of little significance to extend the dehydration time.
Microwave Oven
Dry food should be mixed evenly after adding water. Before heating, it should be covered or wrapped with polypropylene film, or heated with a covered heat-resistant glassware. The food that is heated or cooked each time should not exceed 0 or 5 kg. It is better to cut it into small pieces. When the amount is large, it should be heated in different periods and stirred in the middle. Use high fire as much as possible. In order to reduce the frequency of switching on and off the microwave oven when thawing food, the food can be moved from the freezer to the freezer in advance, and the cold energy in the frozen food can be fully utilized.
Gas
Cooking time is shorter with high fire than with low heat, which can reduce heat loss. However, the fire should not be allowed to exceed the bottom of the pot to avoid waste of gas. When the temperature is high in summer, do not cover the water before boiling water, let the water with lower temperature than air exchange heat with air, and then cover the water when the natural temperature rises to the air temperature, which can save gas. Before cooking, wipe off the water drops outside the pot. The food that can be cooked should not be cooked by steaming as much as possible. The food that is not easy to be boiled can be cooked in a high-pressure cooker or a stainless steel pan without cooking fume, and cooked in a microwave oven, etc., which can also help to save gas. Holding a short meeting is also a kind of economy, which can save electricity for lighting, air conditioning and sound reinforcement. Expired perfume can be sprayed in dry flowers stuffed into pillows, laundry water and trailing floors. Pull out the plug of any electrical appliance as soon as it is not in use.
Means of transportation
Try to use public transportation. When you go shopping by car, you should have a shopping plan and buy enough at one time. More walking, cycling, more buses, more light rail, less driving.
Energy saving in driving: avoid cold start, reduce idle time, avoid sudden speed change, select appropriate gear, avoid low gear running at high speed, change oil regularly, do not open windows at high speed, and tire pressure should be appropriate.
Use more instant messaging tools such as email, MSN, QQ, etc., use less fax printers and plant more trees.
Carbon dioxide from transportation accounts for more than 30% of greenhouse gas emissions. One of the best ways to reduce such emissions is by bus. Public transportation saves nearly 5.3 billion liters of natural gas a year, which means reducing carbon dioxide emissions by 1.5 million tons, according to the Public Transport Federation of America.
Drive less cars and ride more electric bicycles
The biggest advantage of electric bicycle or the coming electric vehicle is zero emission, low noise, no pollution, energy saving and environmental protection. According to the European electric bicycle safety standard en15194 "electric assisted bicycle", the definition of electric bicycle is: the bicycle with auxiliary motor and pedal, but it can not be driven by the auxiliary motor alone. The standard covers the range of electric bicycles: the voltage does not exceed 48VDC, the maximum continuous rated power is 0, 25kW, and the output power gradually reduces to zero when the speed reaches 25km / h or stops pedaling. However, China's GB17761-1999 "general technical conditions for electric bicycles" has added a controversial clause, and the mass (weight) of electric vehicles should not be greater than 40 kg.
