  A small number of (perhaps only 6) broken-symmetries, marked by the edges of
a hierarchical series of physical {\em subsystem-types}, underlie the delicate
correlation-based complexity of life on our planet's surface. Order-parameters
associated with these broken symmetries might in the future help us broaden our
definitions of community health. For instance we show that a model of metazoan
attention-focus, on correlation-layers that look in/out from the 3 boundaries
of skin, family & culture, predicts that behaviorally-diverse communities
require a characteristic task layer-multiplicity {\em per individual} of only
about $4 \frac14$ of the six correlation layers that comprise that community.
The model may facilitate explorations of task-layer diversity, go beyond GDP &
body count in quantifying the impact of policy-changes & disasters, and help
manage electronic idea-streams in ways that strengthen community networks.
Empirical methods for acquiring task-layer multiplicity data are in their
infancy, although experience-sampling via cell-phone button-clicks might be one
place to start.
