Each year, thousands of cities around the world recognize Earth Hour by having landmarks go dark and asking residents to turn off their lights.
Earth Hour, an event that encourages participation in fighting climate change, will look different in 2020 as the world faces an unprecedented battle against the coronavirus pandemic.
Instead, the World Wildlife Fund, which organizes the event, is advising that Earth Hour is celebrated digitally on Saturday.
"Now is not the time to pause our collective work, but a time to respond more creatively, work more collaboratively, and listen and adapt more effectively," the Earth Hour website reads.
WWF offers plenty of ways for individuals to participate online.
Earth Hour takes place at 8:30 p.m. local time.
