Yesterday, March 28, from 8.30 pm to 9.30 pm local time, hundreds of millions of people around the world switched their lights off to show global leaders they want strong action to tackle climate change.
This global event, called Earth Hour, is organized by the World Wide Fund for Nature (WWF) and is held on the last Saturday of March annually. People are asked to turn off their non-essential lights for one hour to raise awareness towards the need to take action on climate change.
Spain was one of the participants. Madrid, Sevilla, Barcelona and Bilbao are some of the Spanish cities that switched off their lights for an hour.
