Humans as natural agents alter or disturb, but can restore.

 

ecological vs. chemical cycles, biogeochemical nutrient cycles, laws of the minimum and optimum, thermodynamics & entropy, ecosystems, biosphere, loss, rates, biomass, net vs. gross primary production, radiant vs. geothermal energy, capacity.

 

Dividing the world in two in order to analyze and know its three part-harmonics.

habitat + biotic community = ecological system

Why study ecology?

 

The habitatĐor geographical setting of any place that has a defined areaĐis the foundation of any measure of the influence of inorganic factors on the eventual quality of living conditions:

 

The A , B , Cs of habitats. Acid and alkaline, Bearings for bearing, Conservation. Such a study can protect you, redirect you, and motivate you to act.

 

More details.

Acid rain, fog and snow physically affects east & west, United States.

 

 

Bearing means 1) the direction 2) the relation 3) the content of places; an essential alignment among points that are directly connected, or tangential to one's destination.

 

̉the uneven distribution of mineral resources.Ó P. 172

 

Bristol Bay Alaska where a mining development conflicts with habitats that facilitate five kinds of salmon migration, feeding & serves as a gateway to spawning grounds.

 

Conservation

 

The initial condition of effective development is conservation of resources for continuing future use.

Dialectic: not one or the other but both must be present!

 

            As a method the dialectical means

can be used to analyze the complexity of ecological systems and human input and output as impact.

Ecosystems are functional necessities of all life, dominance rests precariously on the capacity of ecological systems to operate while recovering from intrusions.

SummaTION

A study of limits:

̉relatively stable ecosystem functioning depends on a vast diversity of organisms [and functional living units or guilds] , and that human beings are unlikely to be capable of assembling reasonably stable  large-scale ecosystems –especially ones able to adjust to constantly changing conditions.Ó
