It has been argued that the early years have the greatest potential to impact on lifelong learning with regard to equality for sustainability (UNESCO, 2008). This study demonstrates how very young children may develop behaviours, attitudes and habits that can have a long-term influence on their actions with regard to sustainability. This research project investigated ways of thinking about poverty and food security with children in a low-income community. Fifty two children, aged six-seven years, attending a Western Australian public primary school were invited to share their ideas about families' access to food from a perspective of wealth and poverty. The single case study method demonstrated how sustainable development in broader terms may be addressed with young children to enable them to express their points of view on economic and social as well as environmental issues. Project findings indicated that the children understood the relationship between work, money and the capacity to access food. They also had an optimistic outlook on how to remove inequality, or 'how to make things fair'.
