The theme of the joint 14th World Congress of Bioethics and 7th National Bioethics Conference Congress "Health for all in an unequal world: Obligations of global bioethics" is of critical relevance in the present global context. Although the world is better off in terms of improved health status of people by many measures than before, there exist colossal gaps across and within populations. Much needs to be done to respond to the lack of access to healthcare, poor quality of living and working conditions, and deteriorating quality of overall environment which affects more adversely the already deprived. We take this opportunity to make a few observations about the current status of affairs on this front, and offer brief analytical insights into the complex origins of the global health scenario characterised by disparities. We revisit the original conception of bioethics and suggest that it is well placed to respond to the current global crisis of inexorably widening disparities in health and wealth, and that global bioethics has an obligation to engage with this crisis.
