I just signed up to the new Earth Hour website for 2008 and I thought you might like to take a look and possibly sign up too. Earth Hour is on 29 March 2008 at 8pm, and it looks like it's going to be really big. So far, as well as Sydney, there'll also be Adelaide, Atlanta, Bangkok, Brisbane, Canberra, Chicago, Christchurch, Copenhagen, Dublin, Manila, Melbourne, Montreal, Odense, Ottawa, Perth, Phoenix, San Francisco, Suva, Tel Aviv, Toronto and Vancouver all turning off their lights for an hour in the name of fighting global warming. And I'm sure there'll be more cities by March. Sign up for Earth Hour with me by visiting http://www.earthhour.org/user/c4nY and join the movement.
