Every year, millions of people around the world turn off the lights for one hour to celebrate Earth Hour, a global event that seeks to raise awareness about the urgency of action against climate change. This symbolic action, promoted by the WWF organization, normally takes place on the last Saturday of March, between 8:30 p.m. and 9:30 p.m., and aims to demonstrate that together and with the smallest actions we can make a difference.
Earth Hour was born in Sydney (Australia) in 2007 and has since become one of the largest environmental movements in the world. Emblematic cities such as Madrid, Barcelona, Paris, London or Buenos Aires turn off their public buildings and their most representative monuments, such as the Puerta de Alcalá, the Eiffel Tower or Big Ben, joining this collective gesture.
In addition to the lights out, Earth Hour invites citizens to reflect on their consumption habits and adopt measures that contribute to sustainability, such as reducing the use of plastics, saving energy and opting for public transport or sustainable mobility. Many organizations and companies take advantage of this moment to organize activities, workshops and talks that encourage participation and environmental commitment.
The main message is clear, every small gesture counts. Earth Hour is an opportunity to join forces and demonstrate that the sum of individual actions can have a great impact. This year, the event remembers the importance of protecting our environment and building a greener future for future generations.
