Grasp the primary and secondary contradictions. On the new journey of promoting ecological civilization construction, it is necessary to handle five major relationships well, analyze important contradictions in ecological civilization construction with a clear problem orientation and strong problem awareness, and then clarify effective methods and approaches to resolve contradictions. For example, high-quality development and high-level protection are a dialectical unity that complements and complements each other. To handle the relationship between high-quality development and high-level protection, it is necessary to plan development from the perspective of harmonious coexistence between humans and nature, firmly abandon development models that damage or even destroy the ecological environment, and firmly abandon the practice of sacrificing the ecological environment for temporary economic growth. To this end, we must firmly establish the concept that green mountains and clear waters are as valuable as gold and silver, consciously limit economic activities and human behavior within the limits that natural resources and ecological environment can bear, promote development to achieve effective improvement in quality and reasonable growth in quantity through green and low-carbon transformation, and continuously shape new driving forces and advantages for development through high-level environmental protection. Adhere to a systematic concept. At the same time, it is also important to note that overall coordination is not about evenly applying force to one's eyebrows and beard, but about adhering to the unity of "two point theory" and "key theory", using key breakthroughs to drive overall progress and achieving key breakthroughs in overall progress. Practice has proven that only by adhering to key breakthroughs and taking effective measures to address prominent ecological and environmental issues can we drive overall work improvement through key breakthroughs. The five major relationships that need to be handled well in promoting ecological civilization construction on the new journey are to integrate the system concept into all aspects and processes of ecological environment protection work, providing a scientific methodology for promoting ecological civilization construction. Coordinate internal and external factors. Fundamentally solving ecological and environmental problems cannot be achieved without strong external constraints, but also by stimulating the internal driving force of the whole society to jointly care for the ecological environment. In the new era, we use the strictest system and strictest rule of law to protect the ecological environment, with strong supervision, strict law enforcement, and serious accountability, making the system an untouchable high-voltage line. Formulate and revise laws and regulations such as the Environmental Protection Law and the Air Pollution Prevention and Control Law, and issue the "Notice on Accelerating the Promotion of Environmental Protection Law and Air Pollution Prevention and Control Law"
