Harm of carbon pollution to life

Formaldehyde is a highly toxic substance, ranking second in the priority control list of toxic chemicals in China. Formaldehyde has been identified as a carcinogen and teratogenic substance by the World Health Organization. It is considered as an allergen and one of the potential strong mutagens. Studies have shown that formaldehyde has a strong carcinogenic and cancer-promoting effect. According to a large number of documents, the effects of formaldehyde on human health are mainly manifested in abnormal smell, irritation, allergy, abnormal lung function, abnormal liver function and abnormal immune function. When its concentration reaches 0.06 -0.07 mg/m3 per m3 of air, children will have mild asthma. When the formaldehyde content in indoor air is 0. 1 mg/m3, there will be odor and discomfort; When it reaches 0.5 mg/m3, it can irritate eyes and cause tears; Up to 0.6 mg/m3 may cause throat discomfort or pain. When the concentration is high, it can cause nausea and vomiting, cough and chest tightness, asthma and even pulmonary edema; When it reaches 30 mg/m3, it will immediately lead to death. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal carcinoma, colon cancer, brain tumor, menstrual disorder, gene mutation in the nucleus, DNA single-strand cross-linking and DNA-protein cross-linking, inhibition of DNA damage repair, pregnancy syndrome, chromosomal abnormalities in newborns, leukemia, and memory and intelligence decline in adolescents. Among all the contacts, children and pregnant women are particularly sensitive to formaldehyde, which is more harmful. It is the main pollutant of decoration and furniture. Its release period is as long as 3- 15 years, and it will volatilize from the deep layer of the material when exposed to heat and moisture, which will seriously pollute the environment and become a worldwide problem that is difficult to solve. It is most harmful to the elderly, children and pregnant women.

Low-carbon economy is an economic model based on low energy consumption, low emission and low pollution, and it is another great progress of human society after primitive civilization, agricultural civilization and industrial civilization. Its essence is to improve energy utilization efficiency and create a clean energy structure, and its core is technological innovation, institutional innovation and the change of development concept. Developing low-carbon economy is a global revolution, involving production mode, lifestyle, values and national rights and interests.

Low-carbon economy is an economic model based on low energy consumption, low pollution and low emission, and it is another great progress of human society after agricultural civilization and industrial civilization. The essence of low-carbon economy is to use energy efficiently, develop clean energy and pursue green GDP. The core is the innovation of energy technology and emission reduction technology, the innovation of industrial structure and system, and the fundamental change of human survival and development concept.

The background of "low-carbon economy" is the severe challenge of global warming to human survival and development. With the continuous growth of global population and economic scale, the environmental problems caused by energy use and their causes are constantly recognized by people. Not only the harm of smog, photochemical smog and acid rain, but also the global climate change caused by the increase of carbon dioxide (CO2) concentration in the atmosphere has been confirmed as an indisputable fact.

In this context, a series of new concepts and policies have emerged, such as carbon footprint, low-carbon economy, low-carbon technology, low-carbon development, low-carbon lifestyle, low-carbon society, low-carbon city and low-carbon world. The result of great changes in energy, economy and even values may be a new way to gradually move towards ecological civilization, that is, abandoning the traditional growth model of the 20th century, directly applying innovative technologies and mechanisms in the new century, and realizing social sustainable development through a low-carbon economic model and a low-carbon lifestyle.

As a frontier economic concept with extensive sociality, low-carbon economy has no conventional definition. Low-carbon economy also involves a wide range of industrial fields and management fields.

How does China develop a low-carbon economy?

Looking at the actions of countries around the world to deal with the development of low-carbon economy, technological innovation and institutional innovation are the key factors, and government-led and enterprise participation are the main forms of implementation. For China, the development of low-carbon economy can start from the following aspects:

First, according to the needs of building a resource-saving and environment-friendly society and energy conservation and emission reduction in China, the national low-carbon economic development strategy is formulated, and the carbon emission intensity evaluation of social and economic development is carried out to guide and lead the direction and behavior of the government, enterprises and residents.

Second, enhance the ability of independent innovation and develop low-carbon technologies and products. Attach great importance to research and development and pay attention to the reserve of medium and long-term strategic technology; Integrate the existing low-carbon technologies in the market and quickly promote their application; Straighten out the enterprise risk investment and financing system and encourage enterprises to develop advanced technologies such as low carbon; Strengthen international exchanges and cooperation, and promote technology transfer from developed countries to China.

Third, levying carbon tax and promoting carbon trading are considered as effective economic policy means. Make full use of the policy synergy of energy conservation and emission reduction and the development of low-carbon economy, and establish a market system and policy system that supports low-carbon economy and adapts to China's national conditions.

Four, pilot demonstration first, sum up experience, and gradually promote. Pilot projects in high energy consumption and heavy pollution industries such as electric power, transportation, construction, metallurgy, chemical industry and petrochemical industry are the key areas for China to explore and develop low-carbon economy. At the same time, actively build a "low-carbon economic development zone", select typical cities and national key energy bases in eastern developed areas for pilot projects, and seek the road of low-carbon economic development in China.

What are the misunderstandings in understanding low carbon?

In understanding the low-carbon economy, we must also clarify some misunderstandings-

First, low carbon does not mean poverty, poverty is not a low-carbon economy, and the goal of low-carbon economy is low-carbon and high-growth; Second, the development of low-carbon economy will not limit the introduction and development of high-energy industries, as long as the technical level of these industries is leading in China, it will meet the development needs of low-carbon economy; Third, a low-carbon economy is not necessarily costly, and a large part of the potential for reducing greenhouse gas emissions is negative, and high-cost technology is not needed, but some policy obstacles need to be overcome; Fourth, low-carbon economy is not something that needs to be done in the future, but should start from now; Fifth, developing a low-carbon economy concerns everyone. Preventing global warming requires international cooperation, which concerns every country and region on earth and everyone.

Expert: The theory of "20 12 doomsday" holds that an unfounded low-carbon life is human self-help.

Respond positively and plan ahead.

Enhance the ability to defend against meteorological disasters

Reporter: In the face of global warming and frequent extreme weather events, how should government functional departments respond?

Shi Yuguang: Under the background of global warming, extreme weather is increasing, that is to say, extreme heat, extreme cold, extreme dryness and extreme humidity are all increasing. Blizzard and rainy weather occurred in northern Xinjiang, and severe drought continued in southern Xinjiang. In the face of change, we should not worry too much, but do something.

In the face of frequent natural disasters, human beings should take the initiative to deal with them. At present, governments at all levels, from central to local, attach great importance to the work of coping with climate change, and cope with and mitigate the losses caused by climate change. Especially when extreme weather and disasters occur frequently, it is very important to improve our defense ability.

As a meteorological department, there are two main tasks: one is to deal with climate change, and the other is to do a good job in disaster prevention and mitigation. Disaster prevention and mitigation work is how to improve human understanding of nature and how to improve the defense ability against bad weather and various meteorological disasters. This requires not only the joint efforts of the government and society, but also the improvement of popular science knowledge and defense ability. To sum up, it is necessary to strengthen the ability and level of human beings to cope with and defend against natural disasters.

In addition, it is necessary to strengthen the ability of monitoring, forecasting and forecasting extreme weather, and improve the accuracy and timeliness of forecasting major meteorological disasters. At the same time, improve the meteorological emergency system and promote the capacity building of meteorological disasters and extreme weather early warning information release. Seriously study the impact of climate warming on the productivity and volatility of major grain crops in Xinjiang. Strengthen agricultural climate zoning and agricultural productivity distribution in Xinjiang under the background of global warming.

Reporter: The Regulations on Meteorological Disaster Prevention will be implemented soon. What has the meteorological department of the autonomous region done in publicizing and implementing the Regulations, especially what measures have been taken in meteorological disaster prevention?

Shi Yuguang: Organize the implementation of meteorological monitoring and disaster early warning project in Xinjiang, and prepare the emergency plan for meteorological disasters in the autonomous region; The meteorological bureau of the autonomous region organized a symposium on multi-sectoral meteorological disaster prevention and emergency management to lay the foundation for promoting the establishment of a multi-sectoral linkage mechanism for meteorological disaster prevention; Efforts should be made to improve the coverage of rural meteorological disaster early warning information and fully understand the problem that meteorological information reaches the "last mile" in rural areas. At present, more than 900 sets of rural meteorological information speaker systems have been established in Xinjiang, with 45 meteorological information officers19. Strengthen the propaganda work of climate change and meteorological disaster prevention, so that the public can objectively and scientifically understand the laws of global warming and regional climate response, adapt to and minimize the impact and losses caused by extreme weather events; Strengthen the assessment of the impact of climate change on Xinjiang and the research on the causes and mechanisms of extreme weather and climate events under the background of climate warming.

Energy saving and emission reduction, low-carbon life

Reporter: Climate change will have a great impact on the global economy and the lives of people in various regions. As ordinary citizens, what can we do to deal with climate change?

Shi Yuguang: Many people are thinking about the same question. What can we leave to the next generation? Is it a green ecological world or a disaster-prone earth? What can you do as an ordinary citizen? It's actually quite simple. To save energy and reduce emissions and live a low-carbon life, we should start with these small things of daily clothing, food, shelter and transportation.

For example, buy less clothes; Stay in a hotel to reduce the number of times to change sheets; Washing clothes in an energy-saving way; Reduce the consumption of livestock products; Moderate drinking; Reduce smoking; Energy-saving decoration; Reasonable use of air conditioners and fans; Reasonable heating; Energy-saving lighting is used in homes and public places; Driving less than one day a month; Use cloth bags instead of plastic bags; Reduce the use of disposable chopsticks; Use elevators as little as possible; Pay attention to energy saving when using refrigerator; Turn off the electrical appliances at the right time; Rational use of water; Reasonable use of paper; Rational recycling of municipal solid waste; Put out the outdoor landscape lights in time at night.

For every citizen in society, it should be every citizen's responsibility and obligation to adapt to and slow down global changes, which requires the participation of the whole society.
