How do you improve the lives of the very poorest people? Sometimes it\u2019s just a question of doing the simple things.
In Greece, where an economic downturn has left thousands of people homeless on the streets, three friends have found a way to provide them with a basic need \u2013 clean clothes. They bought a van and fitted it with washing machines, so they can do the washing wherever it\u2019s needed.
In Malawi, the problem-solvers have turned their minds to another basic need \u2013 vision. They are building a network of new opticians and wire-frame glasses-makers which aim to improve the eyesight of even the poorest in society.
