Are you familiar with the MDGs?
I hope that they have become so familiar that everyone knows about them, and about the goal to achieve these eight goals by 2015 - just seven years from now.
It's possible. It only requires each country to increase foreign giving by 0.7% - that's "point seven percent." Less than one percent. Non-profit organizations, communities of faith, and individuals can participate by committing 0.7% of their income to achieving these goals. My support is going to the Dominican Republic right now, to a community that I got to know several years ago through a church mission trip.
There are lots of places to learn more about the MDGs, like the UN MDG website, or at at the ONE Campaign site. And here's a video I just saw on youTube which I think is excellent.
