Not that kids these days need much prompting to rouse on their parents for doing the wrong thing environmentally, but you ever needed a a fun way to get them engaged, consider PlanetSlayer. It is a curiously irreverant online project from Australia’s national broadcaster. Hip, young thing Greena, the Worrier Princess and her faithful sidekick pooch, lead kids through all manner of eco adventures via cartoon videos, games, factoids and even greenhouse gas calculators. The site is so chock full of eco infomation it would make a small head spin, or a grown-up one for that matter. Like the annual phantom energy used to power appliances on ‘standby’ mode would be sufficient to run a fridge for year. Or how an 100 watt incandescent light bulb generates a kilogram (2.2 lbs) of greenhouse gas every 10 hours it runs. Not sure about the shoot-em-up space game, but maybe that’s what you have to do to hold young boys attention these days, especially when the resident hero is a girl. ::PlanetSlayer.
