I have been trying to put this countdown button on here to promote earth day but you cannot embed swf! Find it at www.earthday.net
I also tried their carbon footprint quiz, but I had to be Australian as they have not put UK in it yet! Results not favourable but I wonder whether it is accurate since that is not where I live.
Come on earth day, get it together – after all you say that next year is your 40th anniversary so you should have plenty of resources available.
