natural environment

Untouched wild spaces

The natural environment encompasses the physical world as it exists without human modification—ecosystems, wildlife, climate, landforms, water systems, and atmosphere.

It contrasts with built or artificial environments: We need to protect the natural environment from industrial pollution.

The phrase often appears in environmental policy and conservation contexts, emphasizing what humans inherit rather than create.
