The most significant landscapes around the world switched their definitive lights off celebrating the "Earth Hour" on Saturday.
Celebrated for the first time in 2007, the aim of this hour is to raise public awareness for the environmental issues the Earth is facing such as pollution, climate change, and global warming.
Millions around the world were asked to switch the unnecessary lights in their homes for an hour starting from 8:30 pm to 9:30 pm in local time in a call for respecting nature.
