What are you gonna do?

Spoor said something in calss as we were all getting ready to leave. He said something along the lines of, "The rest of the world is living in poverty, what can you do besides worry about how you can get your next pair of Ugg boots?" Spoor is right, most of the world can live on less then a dollar a day, the cost of a pair of Ugg boots could feed someone for 160 days! The question we need to ask ourselves is "As high school students, what can we do?" Everyone always tells us we could make the differnce, but its a big world and the bubble of Palatine Illinois really isnt that big. So how can a few little high school kids change the world? I really don't know. I metioned in class that over spring break I am going to South Africa for ten days, I cant wait to see the world more up close. I know that going for ten days might not change the world but at least its a start, but there has to be something more we can do. Any ideas?
