The environment includes natural systems and the human-made and human components that shape life. Air, water, land, plants, animals, institutions, settlements, and technology interact. Understanding these relationships helps explain both environmental opportunities and human impacts.
Learning Objectives
- •Distinguish natural, human-made, and human components
- •Explain interdependence within an ecosystem
- •Relate technology and institutions to environments
- •Identify responsible ways to use shared resources
Key Concepts
Environment is interconnected
Changes in one component can affect soil, water, organisms, livelihoods, and settlements.
Ecosystems include living and non-living parts
Energy, water, nutrients, and relationships connect organisms with their physical surroundings.
People are both dependent and influential
Human choices use resources and transform landscapes, so responsibility includes understanding consequences.
Terminology
