Introduced the theme of the 20th World Conference on Soil Science and delivered speeches on two subjects, namely, soil and peace and soil safety, in response to the important issues of soil science on soil and environment, soil and human activities. In the topic of soil and peace, the two professors in the United States introduced the discussion on the relationship between soil and peace. A professor from South Korea introduced the positive efforts by South and North Korea to gradually move toward reunification of the Korean Peninsula through soil science research cooperation. In the topic of soil safety, the contents of the report on the concepts of soil safety and the meanings of five levels introduced by scholars from Australia, the Netherlands, Indonesia and other countries were introduced. Through the introduction, it is expected to expand readers’ innovative thinking on some important issues related to soil science, provide new perspectives for relevant research fields, and further raise awareness of the role of soil in the ecological environment and the development of human society.
