🍀Chicago's tradition of dyeing the Chicago River green for St. Patrick's Day started in the 60s by plumbers.
🌍The tradition has become iconic, attracting thousands of people from around the world to witness the green river.
🌿While the exact ingredients of the green dye are a secret, it is considered safe and vegetable-based.
🌊Environmental groups question the transparency of the dye and its potential impact on the river ecosystem.
💚The green dye flows from the Chicago River to the Mississippi River, the Gulf, and eventually the Atlantic Ocean, symbolizing a green path from Chicago to Ireland.
