Gus,
Didn't mean to hijack your thread.............I find that if I think about big issues like Global Warming, it helps me to think about my personal behavior and it's impact.
The catch phrase "Think Globally, Act Locally" comes to mind. What can one person do?.........alot.
Do I recycle everything I can?
Do I turn lights, TV, stereo, whatever off when I leave the room?
Do I consolidate trips when possible?
Do I turn the thermostat up or down when leaving the house?
Do I turn my amp off when I finish practicing (maybe I should buy an acoustic)?
The little stuff really adds up with many people over time.
Just sayin'...........
