Energy Transfer: Energy conversions underlie all ecological processes. Energy cannot be created; it must come from somewhere. As energy flows through systems, at each step, more of it becomes unusable.
Interactions between Earth Systems: Earth is one interconnected system. Natural systems change over time & space. Biogeochemical systems vary in ability to recover from disturbances.
Interactions between different species & the environment: Humans alter natural systems & have had an impact on the environment for millions of years. Technology & population growth have enabled humans to increase the rate & scale of their impact on the environment.
Sustainability: Human survival depends on developing practices that will achieve sustainable systems. A suitable combination of conservation & development is required. The management of resources is essential. Understanding the role of cultural, social, & economic factors is vital to the development of solutions.
