Earth Hour is a global action of solidarity, vision, and unification in the face of the ongoing climate crisis and loss of biodiversity. With the effects of climate change and global threats affecting more and more people, there has never been a more necessary time for us to come together to restore our rich biodiversity for a sustainable future for all. Earth Hour is a worldwide movement established by the World Wide Fund for Nature (WWF) which has taken place annually since 2007. The event is held every year to encourage individuals, communities, and businesses to switch off non-essential electric lights for one hour as a commitment to protect and respect the planet. So turn off your electric lights at 8:30 tonight.
