I'd like to know about the geo-socio-economic backgrounds of the volunteers. Were they all from the USA? Europe? or Peru?

We also need to move on from the word 'race'. It doesn't matter how its used, it still serves to divide us into 'us and them'. It doesn't matter what hue people's skin is we are all human, the same race. This is why racism is the dumbest most illogical belief a person can have and anyone who is racist should be ashamed of themselves.
