You may have heard of Earth Day, but have you heard of Earth Hour? Earth Hour is a global grassroots movement that began in Sydney, Australia as a lights-out event to raise awareness on climate change. Started in late March 2007, Earth Hour became an annual event where people choose to spend at least one hour doing an activity that positively affects the environment, such as simply keeping your lights off for an hour. Millions of people today celebrate, and this event has led to incredible strides taken toward sustainability around the world, to include real policy change that helps prevent more habitat loss.

Earth Hour 2024 will be from 8:30 to 9:30 p.m. on March 23. Activity ideas can also be found here.
