<p>Myths and cultural traditions have historically influenced human relationships with the natural world, occasionally leading to harm but frequently fostering conservation. However, some members of the scientific community remained less vocal about certain myths and beliefs due to the ostensible positive outcomes. Myths and superstitions, at times, contributed to the destruction of natural systems, including the killing of animals or even humans to appease the deity or to prepare medicine. In these cases, conservation biologists try to prevent the incidence by explaining the science behind it. Contradictorily, in some cases, numerous communities around the world protect various natural resources, such as sacred groves, sacred animals, and sacred ponds, due to taboos and fears associated with certain myths or superstitions. Sacred groves, sacred ponds, and other culturally protected sites illustrate the role of belief systems as informal conservation strategies, safeguarding biodiversity and ecosystem services across generations. In the context of globalisation, consumerism, and developmental pressures, these systems are experiencing rapid deterioration. This review examines the historical origins and global presence of sacred groves, evaluates their ecological and cultural significance, and critically analyses the ethical dilemmas associated with belief-driven conservation. It emphasises that myths and taboos, although impactful historically, cannot alone sustain biodiversity under contemporary challenges. The future should focus on merging the ecological insights of traditional practices with management models that are both scientifically grounded and rooted in the community. Reframing sacred groves as dynamic entities of sustainability allows societies to enhance their cultural identity while strengthening ecological resilience. This approach provides valuable insights for developing inclusive, ethically responsible, and scientifically robust conservation strategies in a rapidly evolving environment.</p>
