Earth Hour, the world’s greatest event for the fight against climate change is back on Saturday March 26, 2022, In Paris, like in some 7,000 cities in 188 countries, millions of people and emblematic monuments turn off their lights to raise awareness.

This year, let us not forget about Earth Hour 2022 taking place this Saturday March 26, from 8:30 p.m. to 9:30 p.m.. This event that makes thousands of peoples’ and thousands of iconic monument’s lights go off. As it happens every year, the event gives Nature pride of place. And this year, the 16th edition of Earth Hour is devoted to world's eco-citizen acts.

Everywhere throughout the world, WWF asks the entire civil society, from citizens to companies without forgetting the local collectivities and governments, to think about how precious our planet is and that it is vital to protect it. For one hour, Paris will turn off the exterior light of over 300 public buildings including the Arc de Triomphe, the Sacred Heart, the Opéra Bastille and the City Hall.

Major gathorings are also planned around national monuments to celebrate nature. The Eiffel Tower will turn its lamps off around 8:30 p.m. to mark the capital city's commitment to fighting against global warming.

Initiated in 2007 by WWF to raise awareness, especially those of the decision-makers, Earth Hour first took Sydney into the dark. In 2012, hundreds of million people in about 4000 cities and 126 countries turned off their lights for one hour. This year, we count 154 countries joining the movement. Across the world, lights will be turned off: the Eiffel Tower, like the Empire State Building, the Gizeh pyramids, Rome’s Coliseum, Rio’s Christ the Redeemer, Athena’s Acropolis, the Burj Khalifa tower in Dubai, the Forbidden City… Thousands of prestigious monuments will be turned off for this event.

Beyond the symbolic gesture that turning lights off for sixty minutes is, Earth Hour participants are also invited to join the movement launched by WWF in the world to reduce their greenhouse gas emissions. You need to know that by adopting simple and automatic gestures, like thousands of other people, you can save energy while preserving the environment. And this without harming your daily comfort!

This global event simply aims at raise awareness so that each and everyone of us can ensure one’s future. The goal is not to switch electricity off but simply turn the light off (or the ones not vital: goodbye red lights and other street lights…) to be seen.

Did you know that between 1970 and 2014, vertebrate populations - fishes, birds, mammals, amphibians and reptiles - dropped by 60% on the world scale? This decrease equals 89% in tropics, South America and Central Americal. If we were paying for fresh air, drinkable water, food, the cost would be about 125,000 billion dollars per year, which is more than the world GDP (80,000 billion dollars a year). Intensive farming, soil deterioration, intensive fishing, climate change, plastic pollution: the main threats weighing today on biodiversity - degradation and lost of their environments, excessive exploitation - are related to human activities.
