In Judaism, the natural world plays a central role in Jewish law, literature, and liturgical and other practices. Within the diverse arena of Jewish thought, beliefs vary widely about the human relation to the environment, though the rabbinic tradition has put Judaism primarily on an anthropocentric trajectory. However, a few contemporary Jewish thinkers and rabbis in the US and Israel emphasized that a central belief in Judaism is that the Man (Ha Adam - האדם whose root comes from Haadama (earth) - האדמה, in Hebrew language), should keep the Earth in the same state as he received it from God, its eternal and actual "owner" (especially for the land of Israel), thus the people today should avoid polluting it and keep it clean for the future generations. According to this opinion, Judaism is clearly in line with the principles of environmental protection and sustainable development.
