Lights out! On Saturday, March 25 at 8:30 p.m. local time, 180+ countries and territories will dim their lights to honour Earth Hour as a way to raise awareness, and demand action on biodiversity loss and climate change.

For 15 years, households around the world have unplugged and switched off their lights at home for 60 minutes as a symbol of commitment to our planet in need.
