9. Perspectives on the Environment Engaging the Congregation Urban Context Making the Problem Local Making the Problem Global

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

11. Urban Context tennessee.gov

12. Health 6,000 deaths in Ontario from Asthma caused by US smog. Ontario CAN 13 M people Of 92,000 total deaths per year.

13. Making the Problem Global Why? How?

14. Glaciers Glacier runoff year- round Causes productive ecosystems that would otherwise be less productive.

15. GlaciersEcosystems Abundant Ecosystems cause high density of population. 1/3 of world population!

16. GlaciersEcosystemsPopulation.

17. GlaciersEcosystemsPopulation. Global Climate change is partial cause of the glaciers melting. No longer a year long supply of water.

18. GlaciersEcosystemsPopulation. What is going to happen to 1/3 of the world population?

19. Thats why The world is one living organism. All organisms share the same DNA structure. We are the same organism just divided, changed, and recombined.

21. Engaging the congregation Generation Y Start small? Sewing a seed

22. Starting small forms

23. 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.

76. Prioritizing based on unique situation

77. Your unique situation See provided sheet. Building use Climate High wind or solar region?

78. Find the bills What is the annual heating cost and all- inclusive rate? (by month) What is the annual electrical cost and all- inclusive rate? (by month) What is the annual water & sewer cost and all-inclusive rate? (by month)
