An inter-connectedness of its own

They call them 'raw materials' and 'natural resources'. Both terminologies conceal the fund-service character of the value of what God has granted. 

The terminologies emphasize their value as stock-flows. 'Natural capital' says it better because it conveys the notion that what occurs in Nature is happening (and must be happening) in a sustainable way. That is to say that what is happening in nature has a logic and an inter-connectedness of its own, which inter-connectedness results in that sustainability, and which we, mankind, must respect. The respecting of that inter-connectedness is a manifestation of our covenant with our divine partner whose on-going work our covenant asks us to honor. 

Here sheviit differs from Shabbos. Sheviit recognizes His on-going work while Shabbos recognizes our imitating the work that He had done but from which on the seventh day of Creation He desisted.  As such, in a sense, sheviit is more immediate a manifestation of the covenant with the divine whereas Shabbos is only a sign, an 'ot' of that covenant.
