at 8:430 P.M on 28th March, all the people will switch off their light and get darkness to sow their curiosity regarding climatic changes.

“Coming off the warmest year on record, more than ever Earth Hour arrives at a critical time to ignite climate action,” said Lou Leonard, vice president for climate change, World Wildlife Fund. “Just as the nations of the world are preparing their commitments for the UN climate talks in Paris, millions of people across the globe will celebrate Earth Hour and send an inspiring call for strong climate action.”

This Saturday will mark the largest Earth Hour celebration ever, with 172 countries and territories and more than 7,000 cities participating. From Sydney to San Francisco, millions of people and more than 1,200 iconic landmarks, including One Times Square in New York, the Gateway Arch in St. Louis, and many bright lights along the Las Vegas strip will go dark, shedding light on a global movement to protect our planet.

“The world is facing a climate crisis. Without action, humanity, wildlife and the planet we know and love will suffer,” said Jared Leto, WWF Global Ambassador. “Join people around the world for Earth Hour, and turn off your lights for one hour on March 28th at 8:30 p.m. to show your commitment to climate change action. It’s our time to speak up and demand a better future for our planet.”

Each year, Earth Hour supporters come together to show their commitment to protecting wildlife, forests and communities impacted by climate change. While turning off the lights for an hour serves as a symbolic gesture, everyone is encouraged to go beyond the hour to demonstrate each person’s power to fight climate change. Simple individual actions, from lowering the thermostat on the hot water heater, to switching to renewable energy, or even simply biking, walking or taking public transportation to work, all have a global impact.
