Introduction

PHOTO

Celebrate the chance to make a change on Earth Overshoot Day, falling on July 25! This impactful day, first established in 2006 by the sustainability think tank Global Footprint Network, marks an opportunity to deepen our awareness and understanding of our planet's resources. This is the estimated date when humanity's demand for ecological resources in a given year exceeds what Earth can regenerate over that same year. Instead of a gloomy outlook, we view Earth Overshoot Day as an annual wake-up call, a moment for us to galvanize action toward sustainability, an enthusiastic call to "move the date". We are committed to shifting our habits, embracing innovative solutions, and advocating for a world where we live within our planet's means. Let's push for progress and thrive while preserving our precious Earth!
