וַתִּטְמָ֣א הָאָ֔רֶץ וָאֶפְקֹ֥ד עֲוֺנָ֖הּ עָלֶ֑יהָ וַתָּקִ֥א הָאָ֖רֶץ אֶת־יֹשְׁבֶֽיהָ׃
그 땅도 더러워졌으므로 내가 그 악을 인하여 벌하고 그 땅도 스스로 그 거민을 토하여 내느니라
Zohar
Rabbi Yitzchak was visiting Rabbi Shimon, and he asked him about the verse that states: "And the earth was corrupt before the Elohim" (Gen. 6:11). Now, if it was man who sinned and was corrupt, what was the earth's sin? Rabbi Shimon answered, as it is written: "for all flesh had corrupted his way upon the earth" (Ibid.) and, also, "And the land was defiled, therefore I do punish its iniquity upon it" (Vayikra 18:25). So it is mankind that sins. But if you ask what is the sin of the earth, you should know that mankind constitutes the essence of the earth. If mankind corrupts it, it becomes corrupted. This is proven by the verse: "And Elohim looked on the earth, and, beheld it was corrupt, for all flesh had corrupted its way upon the earth."
