Tonight, at 8:30 local time, which for us is EDT, turn off your lights and electrical appliances for one hour. Read by candlelight (but be careful), tell stories, play games like 20 questions, sing, dance, play a flute.
Do any of the wonderful things people have done for millenia. Talk to each other, live, face-to-face. Paint your cave walls. Snuggle.
This is Takoma Park. We're good at this sort of thing. And we care.
Lots of challenges are going on out there. Just search for earth hour challenges or " i will if you will"
