The nature of environmental systems and cycles. How environmental scientists use and portray these concepts with models. Central case: chapter 3 the plight of the st. lawrence belugas.

Leaf, tree, whole forest, mountain range, or the planet all types of systems, smallest to largest) Environmental entities are complex systems that interact with each other. Network of relationships among components that interact with and influence one another. To solve environmental problems, all appropriate systems must be considered. Major earth spheres: geosphere, atmosphere, hydrosphere, biosphere. However, boundaries overlap, systems and subsystems interact. So we have to consider the system as an interacting whole.
