The question of environmental justice is pertinent now more than ever. With rising air quality index (AQI) levels, rapid urbanisation, and, in turn, mindless deforestation in India, there is an urgent need to revisit the ethical concepts of care towards the cosmos in Indian religious traditions. The recent unrest among environmentalists in India to protect the Aravalli hills from mining and construction not only arises from concern for the ecological damage it would cause, but also from a reverential care imbued in the culture and religion of the Indian landscape. This paper will revisit the Hindu mythological stories of the Purāṇas and the kathās, and the Jain cosmology and ecological philosophy as described in the Tattvārtha-sūtra, which form the basis for respect, worship, and care for the cosmos in these religious traditions. It will reflect on the continuance of these traditional practices in dialogue and also examine them in juxtaposition with environmental ethics in contemporary times. This analysis will contribute to the existing discourse on Hindu-Jain environmental ethics by responding to the complexity of dialogue among ritualistic, ethical, and scientific approaches to sustainable living.
