Ecological health or ecological integrity or ecological damage is used to refer to symptoms of an
ecosystem's pending loss of
carrying capacity, its ability to perform
nature's services, or a pending ecocide, due to cumulative causes such as
pollution. The term health is intended to evoke human
environmental health concerns, which are often closely related (but as a part of
medicine not
ecology). As with ecocide, that term assumes that ecosystems can be said to be alive (see also
Gaia philosophy on this issue). While the term integrity or damage seems to take no position on this, it does assume that there is a definition of
integrity that can be said to apply to
ecosystems. The more political term
ecological wisdom refers not only to recognition of a level of health, integrity or potential damage, but also, to a decision to do nothing (more) to harm that ecosystem or its dependents.

A living system exhibits integrity if, when subjected to disturbance, it sustains and organizes self-correcting ability to recover toward a biomass end-state that is normal for that system. End-states other than the pristine or naturally whole may be accepted as normal and good.
