The purpose of this section is to provide for the voluntary
and involuntary termination of the parent-child relationship and for
the substitution of parental care and supervision by judicial process.
This article will be construed in a manner consistent with the philosophy
that the family unit is of significant value to the community, and
will preserve the family whenever possible. When the breakup of a
family is required to ensure the health, safety and well-being of
a child and it has been clearly demonstrated that those charged with
the rights and responsibilities of parenthood are unable to adequately
provide a safe and nurturing environment in which children may grow
into functioning and contributing adults, those rights of parenthood
will be terminated and the responsibilities vested in those persons
or entities who may adequately provide for children. Termination of
the parent-child relationship should be used only as a last resort
when, in the opinion of the court, all efforts have failed to avoid
termination and it is in the best interests of the child concerned
to proceed under this section.
