The environment is the people's livelihood, the green mountains are beautiful, and the blue sky is happiness. A good ecological environment is the most equitable public product and the most universal welfare for the people. He stressed that the concept of green development should be applied to all aspects of ecological protection, environmental construction, production and manufacturing, urban development, and people's life, so as to accelerate the construction of a beautiful China. Under the guidance of this important thought, from Sanjiangyuan to Qilian Mountain, from Shennongjia in Hubei to qianjiangyuan in Zhejiang, from Wuyi Mountain in Fujian to Pudacuo in Yunnan... The land of China is blooming with beautiful scenery of poetry and painting, showing a living animation of the harmonious development of man and nature. Building a green home is not only China's goal, but also the common dream of mankind. This year marks the 50th anniversary of the Declaration on the human environment. In June 1972, the United Nations held the first human environment conference in Stockholm, the capital of Sweden, and adopted the famous "Declaration on the human environment" and the "action plan" for protecting the global environment, which had a far-reaching impact on the environmental governance of countries around the world. For half a century, China has been alerted by the environmental problems of western countries. With a clear understanding of not following the detour of "pollution first and treatment later" of western countries, China has started the process of modern environmental protection and legislation with the world and participated in international environmental governance. In the process of promoting the construction of ecological civilization, China has always been committed to promoting the construction of ecological civilization and global sustainable development to complement each other and advance together, promoting the transformation of global environmental governance system to achieve ecological civilization, and contributing Chinese solutions and wisdom to global sustainable development with the governance of China. From proposing that "man and nature are a community of life", to stating that "mountains, rivers, forests, fields, lakes, grasses and sands are inseparable ecosystems", and then to proposing "jointly building a community of life on earth", China has been deeply involved in global environmental governance with an open mind, and has provided financial and technical support within its capacity for developing countries to improve their environmental governance capabilities. While building a "beautiful China", China is committed to making contributions to the "beautiful world". China has won wide recognition and appreciation from all over the world for its broad mind. As pointed out by the British scholar Martin Jacques, China has provided a "new possibility" and opened up a new path of civilization development featuring win-win cooperation, co construction and sharing. China actively participates in international cooperation on climate change, promotes the joint construction of green "the Belt and Road", and makes the solemn commitment of "carbon peak and carbon neutrality"
