In July 2020, the Supreme People's Procuratorate deployed a three-year special supervision activity on "safeguarding a better life through public interest litigation" to procuratorial organs nationwide. System governance that highlights issues. On August 17th, the Supreme Procuratorate held a press conference to report on the special supervision activities and released typical cases, allowing the people to test the effectiveness of case handling. The press conference has responded one by one to public concerns about cross administrative environmental public interest litigation and food safety issues. With the continuous acceleration of the top-level design and institutional system of ecological civilization in China, the field of ecological environment and resource protection has become the most important field of public interest litigation procuratorial work, with the largest number of cases handled, the richest types of cases, the widest coverage, and the greatest social impact. The value of the system is increasingly receiving attention and recognition from all sectors of society. It is understood that the proportion of public interest litigation cases in the fields of ecological environment and resource protection to the total number of public interest litigation cases has always been maintained at around 50%. In the past three years, there have been some changes in the handling of public interest litigation cases in the field of ecological environment and resource protection by procuratorial organs. Faced with the constantly evolving situation of handling cases, how can procuratorial organs adjust their work strategies and methods? Hu Weilie, Director of the Eighth Procuratorate of the Supreme People's Procuratorate, introduced that in the past three years of carrying out special supervision activities, the procuratorial organs have handled public interest litigation cases in the fields of ecological environment and resource protection.

In addition to traditional environmental factors such as atmosphere, water, and soil, it also involves forest diseases and pests, rare birds, endangered plants, wetlands, nature reserves, cultural relics, and natural relics, presenting diverse characteristics. In the past three years, the quality and efficiency of handling public interest litigation cases have been continuously improved, and the procuratorial organs have successfully handled a large number of influential cases such as the "Wanfeng Lake Case" and the "Nansi Lake Case". From handling individual cases to supervising similar cases, thereby promoting the governance of litigation sources and systems. In addition, we will explore the punitive compensation system for ecological environment infringement, continuously enrich the use of carbon sequestration as a substitute for restorative judicial methods such as ecological environment restoration, and develop a big data legal supervision model to empower environmental resource prosecution and case handling. Ecological environment and resource protection are one of the "four legal fields" initially established in the public interest litigation and prosecution system, and the damaged social public interests in this field often have characteristics that cross regions and departments. Cross regional and cross departmental collaborative protection is an essential issue in the field of ecological environment and resource protection, and also a difficult point that cannot be avoided. "In the press conference, Zhang Xueqiao, Deputy Prosecutor General of the Supreme People's Procuratorate, specifically mentioned major cross regional cases such as the Yangtze River Basin Ship Pollution Control Project.
