Cities around the world were turning their lights off Saturday as part of Earth Hour, with this year's theme highlighting the link between the destruction of nature and increasing outbreaks of diseases like COVID-19.
The big picture: From Australia, to America, cities switched landmark lights off for an hour at 8:30p.m. to mark global action on climate change. Organizer WWF said in a statement, "COVID-19 has given us a stark warning of the risks, vulnerabilities and inequalities of our interconnected systems."
