It's once again upon us, Earth Hour is here.
Take an hour on Saturday, March 27 - a specific hour, in fact: 8:30 to 9:30pm - to turn off your lights to help raise awareness of excessive CO2 and other polluting, wasteful forms of energy.
From 8:30pm, turn off all your lights, your TV, your computer, everything that uses energy to run. Light some candles, play some cards, work on a little lucubration, or whatever activity that's fun to do in the dark tickles your fancy.
Earth Hour works, but it only works if you take part.
