Over 170 countries went dark for "Earth Hour" on Saturday.
The World Wide Fund for Nature (WWF)-sponsored campaign encouraged people and businesses to turn off non-essential lights from 8:30 to 9:30 p.m.
The campaign ― the world's biggest environmental event ― celebrated its 10th anniversary this year. It started in 2007 as the first global plan to curb climate change.
"We started Earth Hour to show leaders that climate change was an issue people cared about," said Siddarth Das, director of Earth Hour at WWF. "For that symbolic gesture to turn into the global movement it is today, we thank the powerful role of the people who participated in the event."

The campaign has helped protect the waters of Russia and Argentina and raised funds for conservation projects in Southeast Asia and the Amazon for the past 10 years. In Uganda, the campaign has led to a new forest called Earth Hour.
"It would not have been possible if we had not joined together," Das said. "Our enthusiasm has laid the groundwork for protecting the one and only earth in which the whole world lives."
Korea celebrated Earth Hour at major landmarks such as N Seoul Tower and Sungnyemun Gate in Seoul, Hwaseong Fortress in Suwon and the Harbor Bridge in Busan.
