For the fourth year running, nations all around the world are celebrating Earth Hour by turning off the lights at 8:30 pm local time. What started in Sydney, Australia in 2007 has now reached around the globe.
For me, this is an incredible symbol of what happens when people each take a moment of personal responsibility, acting in concert with others around the earth.
What will YOU be doing at 8:30 this evening? [I've got a night ghost stories with friends lined up.]
And tomorrow, when it's over, give a thought to what else you can do to take a stand. Let's work together to fix this mess our species has made, shall we?
