Turn off lights for one hour on Saturday

Earth Hour returns on Saturday. This year's theme is "Reduce, Reuse, Change the Way We Live". Reduce the use of plastic which causes heavy pollution and causes deaths and reuse recyclable waste like paper. In its 12th year, the annual global initiative - recognized as "the world's largest grassroots movement for the environment" - sees millions of individuals and businesses turning off their nonessential electric lights for one hour, to raise awareness about energy consumption and its impact on the planet.
