As we come to the end of the decade declared as United Nations Decade for Biodiversity 2011-2020, the impact humans are having our planet is clear. The current primary school children are the future decision makers, consumers and electors; therefore, they must be exposed to approaches that can assist development that is sustainable and that will prevent further degradation of our planet. A key way to achieve this is to transform the education current and future generations of children will receive. Education must address sustainable development to support the formation of responsible citizens, eager to actively engage in decision-making processes, environmental issues and societal matters. This can be assisted through a focus on a specific approach to Education for Sustainable Development, Biodiversity Education. To add to current research about this approach to ESD, I investigated the effect biodiversity education had on the sustainability consciousness of primary school children. I chose a qualitative method of data collection and analysis through focus group, semi-structured interviews with 5th class students. The results showed that the participants' sustainability awareness, regarding two of the three dimensions of sustainable development, was highly developed; the environmental dimension and the social dimension. There was less evidence of a consciousness for the economic dimension of SD. Therefore, biodiversity education had a positive influence on the participants' sustainability consciousness, making them more aware of sustainability issues and action-oriented to address these issues. However, they lacked one dimension of sustainability; therefore, their sustainability consciousness was not fully developed. Further research is needed to analysis and interpret the rationale as to why the economic dimension was less developed in these participants who attended a school that promotes biodiversity education.
