Learning about water shortage

Olivia is learning about water at the moment, especially the problems in Africa. She watched a video in class today showing how children sometimes had to walk for three hours in one direction just to collect water. She was horrified and wanted to share her new knowledge with us. She is now behaving like the water mafia watching to see if we waste water at home.
Later in the month she is doing a sponsored walk to raise money for a village in Africa. The money raised will go towards better sanitation and a toilet block.
