Three aspects of every ecological problem are:
Mercury is an elemental and compound problem that requires understanding of how nature works.
We are a sentient creature that symbolically represents the world so that we may compare an impression with other people's perceptions.... Our skillfully articulate creation of language requires humans to think with a rich symbolic imagery about the world we encounter. Expressing the depth of that encounter with the world and its various living things is one purpose of telling one another stories about nature. Yet we must be careful to use symbols that adequately reflect the conditions of nature or we run the risk of making mistakes. Adaptive management is a means of testing our assumptions before we make serious errors that entail costly outcomes.
Land as country
Models for seeing relationships among parts.
The biodynamics of the natural world complicates the ability of human policies to restore the natural world. The biological features and functions of the world sustain human civilization in terms of forests, wetlands, ecosystem services and symbiotic associations.
Evolution and natural selection
Laws of ecology
Cosmos as physical reality
We are faced with distinguishing the actual condition from the appearances. This is difficult, to say the least.
Real versus ideal
Rachel Carson's the Edge of the Sea, combines all three ideas in her book.
Museums as sources for solving problems.
Ecological planning method as a means.
The Seashore as contested ground.
