Every year on the last Saturday in March, people from all over the globe darken their homes and their cities in observance of Earth Hour.
Earth Hour began back in 2007 as a way to educate and increase awareness about climate change and the power we each have to make a difference. Over 162 countries participate in Earth Hour, and the idea is quite simple. Starting at 8:30pm local time, the lights and non-essential electronics are turned off for sixty minutes. Of course, you’re welcome to leave the lights off longer, but sixty minutes is the standard. This hour-long celebration is a great time to do a fun family activity like playing board games by candlelight or having a bonfire and roasting marshmallows. If you’re alone this Earth Hour, you can catch up on a good book or just simply sit and enjoy the stars. With all the lights off, you’ll see the night sky so much more clearly.
Here's a look at Earth Hours from the past. The images on the left side are before Earth Hour began, and the images on the right side are in the midst of the celebration.
