When I'm talking about a developing world, I also look at clean-water access - women who are more vulnerable to sexual violence when they're fetching water. And talking about what we have going on here, with our carbon footprints and our emissions, is just as important to me as figuring out how to provide clean water to people who need it in regions around the world.
You cannot see faith, but you can see the footprints of the faithful. We must leave behind "faithful footprints" for others to follow.
Take only memories, leave only footprints.
