About 90 cities and towns in Kazakhstan will join the global Earth Hour campaign by switching off the lights for an hour, the local branch of World Wide Fund for Nature (WWF) said Friday, Xinhua reported.
Saturday will be the third annual Earth Hour observance, which is sponsored by the WWF.
In the capital of Astana, some landmark buildings, such as the Astana-Baiterek Monument, the Presidential Palace, the Supreme Court building and the Independence Palace, will turn off the lights between 20:30 and 21:30 local time.
In Almaty, the largest city of Kazakhstan, the city hall building, the television tower and many other buildings will also join the action.
Major cities in Kazakhstan participating in Earth Hour include Uralskaya, Atyrau, Aktau, Aktobe, Petropavlovsk, Aksu, Chaimey, Karaganda, Shymkent, and Taraz.
In addition, the WWF also called on local people to voluntarily join the global action by turning off their own lights on Saturday night.
The Earth Hour initiative began in 2007 in Sydney, Australia, when 2.2 million people switched their lights off for an hour.
