Implement practices to mitigate light pollution

Rationale: Limiting glare and light trespass from artificial light at night by implementing interventions such as light shields and automated timers helps preserve biodiversity and regulate circadian rhythm of those in the surrounding area, contributing to improved sleep quality, a strengthened immune system, lower stress levels, and decreased risk of cancers.
