The idea behind The Unity of Nature is a strong theoretical theme in a number of scientific and environmental fields from ecosystems ecology, through quantum physics to environmental philosophy and ecopolitics giving rise to an inspiring, optimistic, socially-responsive and environment-friendly worldview. The fields of science and environmentalism have inherited this theme of natural unity through an intellectual lineage that encompasses many non-scientific and non-environmental fields such as sociology, theology and political philosophy. Many of these fields have used natural unity in a way which is in stark opposition to the metaphysical and political desires of those who promulgate the unity of nature for progressive social change.
