• The health of the “context” and the interaction of the “context” with human health
- the physical, social, economic and political environment

Spiritual Health - Aboriginal
The Earth is our Mother, the female giver of Life to all her children, some of whom are human beings.
Decisions must respect 7 generations of our ancestors and 7 generations of our children to come

Alternative Security
Security is better achieved by trying to establish equityrather than dominating

Let’s describe Health inits widest sense:

Health Care
• NOT a determinant of health
• “The majority of the health care dollar is spent in the last 6 months of one’s life” - 1993
• Average health expenditures on people who are in their last year of life is between 50 and 100 times more than expenditures on those who are not. - Health Canada -2005

Uncertaintynot part of our vocabulary
• Obsession with certainty– Double blind trials, critical appraisal– Evidenced based medicine
• The present scientific method is about reductionism– Inclusion, exclusion criteria, controls
![Page 36: Ecosystem Health Restoring the Health in Health Care Healing the Planet - PGS](https://reader038.vdocuments.us/reader038/viewer/2022103100/56813afa550346895da38959/html5/thumbnails/36.jpg)
Uncertainty - not part of our vocabulary
• EH - Can’t find appropriate controls, system has many interactions, etc.– Don’t study it– Absence of data implies no effect
• Complexity ≡ Uncertainty
• Complexity ≠ Complicated
![Page 37: Ecosystem Health Restoring the Health in Health Care Healing the Planet - PGS](https://reader038.vdocuments.us/reader038/viewer/2022103100/56813afa550346895da38959/html5/thumbnails/37.jpg)
Which is the More Important Question?
• Have pesticides used on land been proven to lead to illness in humans?
• Might pesticides cause illness in humans?
Or both!

Accountability
• Meet minimal standards – Health care:
• Single use instruments• Insurance issues, legal departments
– Much $$ spent on non-medical issues
• Limits boundaries
• One-way accountability
• Focus on practices
![Page 46: Ecosystem Health Restoring the Health in Health Care Healing the Planet - PGS](https://reader038.vdocuments.us/reader038/viewer/2022103100/56813afa550346895da38959/html5/thumbnails/46.jpg)
Responsibility
• Striving for excellence– Health Care-responsible for health
• Health in its greatest sense– Single use recyclable /Multiple use– Decisions to improve health
– Bidirectional• Public has a responsibility – behaviour,
resources
– Focus on Values
