Arthur Dahl presents on "Systems Science Beyond Diversity" discussing how diversity alone is not enough and a systems perspective is needed. He provides examples from nature like coral reefs that have high diversity due to cooperation and symbiosis between species. For human societies, diversity is only productive when different groups contribute to governance within a framework of unity and integration guided by justice. True prosperity requires an economic system that embraces diversity and incorporates a moral dimension where wealth serves humanity according to spiritual principles of generosity and justice.
