One year on from the adoption of the UN's new Sustainable Development Goals, they look something akin to a Rubik's Cube. The 17 Goals, and 169 targets within those, applicable to 193 countries, are a colourful and immensely challenging combination puzzle. One cannot be solved without the others; they are inter-dependent.
I recently returned from a trip to visit rural villages in Angola to look at the impact that Unicef's sanitation partnership with Andrex is having on children and families there. It's incredible to think that seven out of ten people living in rural Angola do not have a clean, safe toilet to use. This has a huge impact on the health of Angola's children and one of the reasons the country has the highest rate of child mortality in the world.
