Earth Day 2026
Wie entstand unser Planet, und wie entwickelte sich das Leben? Wie hängt alles voneinander ab? Wir erwandern 18 Meilensteine der Erdgeschichte entlang einer 4,6 km langen Strecke – jeder gelaufene Meter steht für eine Million Jahre! Mit jedem Schritt erleben wir die unvorstellbaren Dimensionen der Zeit und die entscheidenden Ereignisse und Wendepunkte, die unsere Welt geformt haben.
EARTHDAY.ORG’s mission is to broaden, educate and activate the environmental movement worldwide. Growing out of the first Earth Day in 1970, EARTHDAY.ORG is the world’s largest recruiter to the environmental movement, working with more than 150,000 partners in over 192 countries to drive positive action for our planet. Our world needs transformational change. It’s time for the world to hold sectors accountable for their role in our environmental crisis while also calling for bold, creative, and innovative solutions. This will require action at all levels, from business and investment to city and national government. That’s where you come in: As an individual, you yield real power and influence as a consumer, a voter, and a member of a community that can unite for change. Don’t underestimate your power. When your voice and your actions are united with thousands or millions of others around the world, we create a movement that is inclusive, impactful, and impossible to ignore. Every Earth Day can drive a year of energy, enthusiasm, and commitment to create a new plan of action for our planet.
