Protection is any measure taken to guard a thing against
damage Damage is any change in a thing, often a physical object, that degrades it away from its initial state. It can broadly be defined as "changes introduced into a system that adversely affect its current or future performance".Farrar, C.R., Sohn, H., ...
caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like
civil and political rights Civil and political rights are a class of rights that protect individuals' freedom from infringement by governments, social organizations, and private individuals. They ensure one's entitlement to participate in the civil and political life o ...
. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as
ultraviolet light Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30  PHz) to 400 nm (750  THz), shorter than that of visible light, but longer than X-rays. UV radiation i ...

anti-predator adaptation Anti-predator adaptations are mechanisms developed through evolution that assist prey organisms in their constant struggle against predators. Throughout the animal kingdom, adaptations have evolved for every stage of this struggle, namely by avo ...

or otherwise adopting habitats or behaviors that insulate them from potential sources of harm. Humans originally began wearing clothing and building shelters in prehistoric times for protection from the elements. Both humans and animals are also often concerned with the protection of others, with adult animals being particularly inclined to seek to protect their young from elements of nature and from predators. In the human sphere of activity, the concept of protection has been extended to nonliving objects, including technological systems such as computers, and to intangible things such as intellectual property, beliefs, and economic systems. Humans seek to protect locations of historical and cultural significance through
historic preservation Historic preservation (US), built heritage preservation or built heritage conservation (UK), is an endeavor that seeks to preserve, conserve and protect buildings, objects, landscapes or other artifacts of historical significance. It is a philos ...
