The lights of the Eiffel Tower in Paris, France's best-known symbol, were switched off for five minutes at 1930 GMT and the Burj Khalifa tower in Dubai, the world's tallest building, went dark for an hour.
It was lights out in about 170 countries on Saturday as millions of people and thousands of cities took part in Earth Hour, a global effort to draw attention to climate change.
On Saturday, almost all countries, including India, will be switching off their non-essential lights for an hour, from 8.30 pm to 9.30 pm, local time, in support of people's commitment towards energy conservation, proper utilisation of energy sources and awareness about climate change.
According to the WWF, the United Nations family will join the thousands of homes, offices, skylines and monuments that will go dark on Earth Hour's tenth anniversary to put the spotlight on the issues facing the planet, and to inspire millions across the world to live more sustainably.
Earth Hour is scheduled 8:30 p.m.to 9:30 p.m., local time, around the globe because it is the closest hour to sunset in both hemispheres, allowing for the biggest visual impact of lights out everywhere.
At 8:30 p.m. today, you can make a statement about the climate change and environmental impact by celebrating Earth Hour and turning off your lights for one hour. Meanwhile, Chairman Senate Mian Raza Rabbani said Pakistan will play its due role to boost the national climate change resilience, protect lives and livelihoods of the people. The campaign has grown in the past decade from the kick-off event in Sydney, Australia in 2007. The event is a movement millions of people participate in each year.
Anyone staying at the Delta Prince Edward or having a meal in its restaurant Saturday night will have to do so by candlelight, but only for one hour. Be sure to share with friends via social media and use the hashtag #changeclimatechange when sharing your Earth Hour 2017 celebrations!
Abella said the Filipino people's observance of the event signifies that the Philippines is "an Earth Hour hero country".
