Box 5.2 Basic notation for network environ analysis
Flows: fj = within system flow directed from j to i, comprise a set of transactive flows.
Boundary transfers: zj = input to j, yt = output from i. Storages: Xj represent n storage compartments (nodes). Throughflow: T^ = zt + Z f
Non-dimensional, intercompartmental flows are given by g j = fj /Tj Non-dimensional, intercompartmental utilities are given by d j = ("f-j/T. Non-dimensional, storage-specific, intercompartmental flows are given by pj = Cj A^ wtei-e for i#j, Cij =fj/xp and for i =j, pii = 1 + c an where Cii = -Ti/xi.
Non-dimensionless integral flow, storage, and utility intensity matrices, N, Q, and U, respectively can be computed as the convergent power series:
N = G0 + G1 + G2 + G3 + K + Gm +... = (I - G)-1 Q = P0 + P1 + P2 + P3 + ... + Pm +K = (I - P)-1 (1)
The mth order terms, m = 1,2, k, account for interflows over all pathways in the system of lengths m.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
