This study investigated the relationship between animism and environmentalism in an upland rural community in Labo, Camarines Norte, Philippines. A survey of 136 adults identified prevalent animistic customs and practices, moderate attribution of animistic essence to various objects, and high levels of environmental concern and action. Significant positive correlations emerged between some customs and practices and environmentalism, suggesting that certain practices may promote concern and action for ecology. However, the strength of these correlations was generally weak. This could be due to external factors like commercialization, dominant religion, and secularization, which weaken the connection between customs and practices and environmentalism. The attribution of animistic essence to animals and plants displayed a positive relationship with environmentalism, suggesting a link between valuing living things and pro-environmental behavior. Conversely, attributing essence to most of the object categories did not yield significant relationships. These findings highlight the complex relationship between animism and environmentalism. While some animistic beliefs cultivate ecological responsibility, others have a more nuanced influence. Strengthening specific customs and practices and fostering the attribution of animistic essence to living things could be avenues for promoting environmental stewardship within animistic communities. Further research is needed to explore the factors that influence the animism-environmentalism relationship. Understanding these complexities can help develop strategies for nurturing animistic values and empowering environmental movements.
