What is Earth Hour?
What is the purpose of Earth Hour?
WWF describes the event as a symbol of “unity” and “hope” for a sustainable future.
How can I participate?
You can mark Earth Hour by turning off your lights from 8:30 to 9:30 p.m. in your local time zone.
The WWF also recommends that supporters “take action beyond the hour, whether it is supporting a local WWF project or getting involved in Earth Hour campaigns in their own country, or starting the movement in their own community.”
