World Ranger Day is observed every July 31st to raise awareness and funds for the vital work of park rangers who protect natural heritage and cultural treasures worldwide. Established by the International Ranger Federation, this day honors rangers who have been injured or killed in the line of duty, while also celebrating their contributions to environmental conservation. Activities on this day may include fundraising events, guided walks, and screenings of documentaries like "The Thin Green Line." Participants are encouraged to pause and reflect on the sacrifices made by rangers and to spread awareness through social media and community events. With over 100,000 reserves and parks globally, the role of rangers is crucial, as they often face significant dangers, including assaults at an alarming rate.
