The outbreak of COVID-19 from regional level to global level has caused wide criticism and reflec? tion from multiple perspectives among scholars at home and abroad, among which reflection on the relationship between man and nature has become one of the hottest. In order to make the thinking more scientific and practi? cal, the dialectical unity between mankind and nature contained in Marxist view of nature must be reaffirmed in the context of COVID-19. We should advocate the concept of harmonious development between man and na? ture, strengthen the value of harmonious coexistence between man and nature, make it clear that the community of life is the foundation of a community of a shared future for mankind, and deepen the development principle that“lucid waters and lush mountains are invaluable assets”. We should adhere to the practice direction of sus? tainable development between man and nature, realize the unity of ecological content and exchanging form of green production mode, advocate the“de-aristocratic”and“pro-ecological”green consumption mode, improve the ability of ecological governance and system of ecological governance.
