The Great Wall. Times Square. The Eiffel Tower.
Many of the worlds greatest, and most illuminated, monuments will go dark for an hour on Saturday for the eightth annual Earth Hour. More than 150 countries and millions of people will engage in a crowd-sourced conservation effort from 8:30 to 9:30 p.m. local time, highlighting a growing need to protect the environment, while encouraging global action.
"It is always extraordinary to see cities and landmarks involved in Earth Hour, but in 2014 it is the stories and activities happening beyond the hour that show this event has evolved into a movement driven by the power of the crowd,” Andy Ridley, the co-founder of Earth Hour, said in a press release.
This year's event has a heroic partner to help spur people into action as Spider-Man became the first superhero ambassador to join with the World Wildlife Fund-backed project.
