Remembrance Day and reducing consumption

Msgr. Don Clement gave the benediction at the City of Kingston's Remembrance Day service today and he provided, I'm glad to note, a wise exhortation. To paraphrase Msgr. Clement, he called on us to use the liberty won by the sacrifices of our soldiers to ensure that the resources of the world be utilized for the benefit of all people, in all nations, now and in the future.
How can the average Canadian support our troops overseas?
The more I learn about the economic drivers of conflict around the world, the more I appreciate the contribution of the consumption of material goods by people in developed countries. As an example, most recently in the news, the humanitarian crisis in eastern Congo has, as an underlying cause, a struggle to control valuable mines.
So I would venture to say, one way of supporting our troops is by making a personal sacrifice. Cut your personal consumption of "stuff". You'll be making a small but real contribution to peace around the world and making future peacekeeping efforts a tiny bit easier.
