Making the Problem Local
Problem is too big for most people.
 Break it down to the village.

6,000 deaths in Ontario from Asthma
caused by US smog.

◦ Of 92,000 total deaths per year.
Making the Problem Global

Why?

How?
Glacier runoff yearround
Glaciers
Causes productive ecosystems that
would otherwise be less productive.
Abundant
Ecosystems cause
high density of
population.
1/3 of world
population!

What is going to
happen to 1/3 of the

That’s why
The world is one living organism.
•All organisms share the same
DNA structure. We are the same
organism just divided, changed, and
recombined.

Recycling / Composting
Trash trucks get 2 mpg.
 1.5 lbs of air pollution (smoke & carbon
monoxide & carbon dioxide) to haul away
and bury 1.0 lbs of trash.


No immediate economic payback to
congregation, unless you pay for trash by
weight.

Unique Strategies
Variation in use patterns.
Sanctuary use.
Office use.
 Climate regions
 Building age

Avoiding Mistakes
Insulating the wrong way can cause mold
growth.
 Putting in the wrong product can cost you
more.
 Look past product claims that “may save
up to 50%.”
 Environmental Problems: Radon

Use Patterns
Programmable Thermostats:
 Can control days by day and hour by hr.
 If building is unoccupied during night:
Turn back at night by 10-15 degrees.
Savings: 10%
 If building is unoccupied during week:
Savings: 20-30%
Use Patterns
Zoning:
 Controls split forced air or steam to
needed areas only.
