Perhaps you mean "energy conservation", or equivalently, "conservation of energy". That refers to the fact that there is a quantity called energy, which can't be increased or decreased (in a closed system).
There are 20,330 forest and conservation workers receiving a mean yearly wage of $24,670.
Not "change", but "charge". Conservation of charge means that the total charge in a closed system can't change.
There are several laws of conservation; please clarify which one you mean. For example, there is the law of conservation of mass, of energy, of momentum, of rotational momentum, of electrical charge, and others.
