So what is it?
An ecological imagination apprehends and understands the integrity of forms, functions and participants inhabiting an area or coexisting in any place, in order to protect the natural systems on which life and human society together depend.
Developing an ecological imagination means we learn to see reality coherently in what can be described as a place's ecological integrity because the structure and function of the assembled living organisms are understood as working together to form a functional unit.
The effective functioning of the whole nourishes each member according to an elaborate system of interdependent services or feeding relations among all of the participants.
Ecological integrity is understood as a series of interdependent ways of thinking and describing the consistent qualities in the world we observe.
Thus, an imaginative faculty is used for conceptualizing the functionally necessary interplay of physical elements and biological processes that are co-dependent factors contributing to the nourishing conditions of existence.

Glacier National Park, valley on the Idaho and Montana boundary:
An Idaho mountain valley's geographical and vegetational relationships are based, in part, on complex links among water, wildlife, fisheries and human recreation.
Complex relations that contribute to ecological integrity: functional and structural necessity of water, sunlight, temperature, climate, chemical nutrient cycles, moderate acidity and alkalinity (or pH), and the geographical access of living creatures to and from adjacent ecosystems. Each link in the chain of being ties each and every creature to the functional necessity of water, energy, air and landscape. This chain of being is no stronger than its weakest links.
Nature is a problem for humans because we, in our ignorance, avarice, and insecurity, believe we can have something for nothing; cheat the system and get away with biocide.

Environmental factors in cancer
Receptors in the body, cells & tissues alert glands & trigger responses in hormonal secretion.
certain other related responses in glands, organs & metabolism.
Endocrine disrupters are estrogen, androgen and thyroxin mimics (femaleness, maleness, metabolism)
Environmental factors in cancer
Epidemiological studies .... Comparison of the incidence of various cancers among Japanese citizens, American citizens and Japanese who have emigrated to the United States shows quite convincingly that most cancers are attributable to environmental factors.

LOCATION OF CANCER
Recent experiments have shown that a chemical in cigarette smoke is converted in cells into a chemical that is able to activate certain oncogenes.
Somatic-cell mutations trigger the onset of most cancerous diseases. These mutations are caused by environmental agents and, because the affected cells are somatic, the defective genes can not be inherited, However, some rare heritable human disorders may predispose their victims to the development of cancer.
