A fresh approach to economics which considers the principles relating to the major areas of economic study. It takes as its basic assumption that, in practice, economics should have a just and equitable outcome for all those participating in, or affected by, the economy. Economics is approached as a social study, involving all of humanity, but with humanity seen in the context of its place in nature and the universe. The role of nature as the source of wealth and sustainer of life is emphasised. Importing considerations of justice, equality and nature's laws into the study of economics opens up a much brighter prospect for planetary health and prosperity. No previous knowledge of economics is required.
