The document defines the environment as our surrounding world, including both natural and human-made elements that support life. It describes the environment as consisting of three main components: the natural environment of land, water, plants and animals; the human environment; and the human-made environment of objects created by humans. The natural environment can be further broken down into four domains: the lithosphere of Earth's crust, the hydrosphere of water, the atmosphere of air, and the biosphere where all life exists at the interface of land, air and water.
