This seems like a good idea, although I am not confident that the goal will be achieved because 40% of the world's population are without proper sanitation, which was about 2.5 billion people I think - so quite a challenge.  But then again, if enough people supported them then who knows?  I think we as a school should offer some support, for example, a non uniform day.  People who have facebook or twitter can help because the End Poverty Website is there on these sites.  I think we could have an assembly on this topic though because not many people seem to be aware of it, I personally have never heard of it in my life before I saw it on the VLE.
