One of the blogs I enjoy reading is Mark Sayers' blog. Mark is one of the most insightful yet down to earth people around and a profoundly deep thinker - particularly in regards to culture. I highly recommend you subscribe to his feed if you're interested in the impact of culture, particularly in regards to following Jesus (he has also just started a weekly podcast, too, so get onto his site and check it out).
In one of his previous entries, Mark made mention of a some of the resources on the World Vision resource page, Learn About Poverty. I was perusing it today, and was blown away by this clip...
I can't see how anyone could not use that in their youth/young adult ministry - so many helpful discussions that could come out of it. Please go to the site and check out the rest of their resources.
