$25 = water for life for one person. Seriously. Skip just 1 family movie night or fast food dinner out. Stay home, have some at home family activity time, and provide a lifetime of water for someone.
Things are very tight for many people right now, so if you can't donate money, donate your voice! Visit Water.org.
BTW, I've added a category called 'Decreasing World Suck' which is where you'll find posts & links like this going forward. DFTBA!
