First, it’s symbolically vital that you turn on every single light for the appointed hour. Sounds easy enough, but there is always a sneaky bulb out on the back porch or in the garage. Be vigilant. Don’t let even the smallest or least visible globe escape illumination.
Toddlers are especially useful for this. “Just preparing for Earth Hour,” a friend texted before 2009’s event. “Max is loving running through the house turning all our switches on. We think he’s really learning something important!”
If you know anybody in the local council or the film industry, lean on them for a one-night use of something massive for the backyard. These people have got lights that you wouldn’t believe. Point them at your pool and it’ll evaporate like a state Labor party.
Food is important. Put some thought into what you serve. According to as recent study, the basic prawn cocktail has an absolutely massive carbon footprint. Biologist J. Boone Kauffman found that, with transport and refrigeration factored in, just 100 prams of prawns shipped from a typical Asian farm represents a total carbon output of 198kg.
So you’ll be eating prawns, then. Plus pizza. The delivery kid won’t have any problems finding your house for once, what with it being lit up like a supernova.
