Zoe and I like to 'tread lightly'. We've written about it before, here. There are little things like that which you can do, and then there are bigger things, like taking part in Earth Hour.

Check out the new ad, voiced by Cate Blanchett, for this year's event. And then, do it. And maybe tell some friends while you're at it. Being environmentally conscious and socially active is hot; being apathetic is not.

Thankyou. You can sign up here. I will get off my soapbox now.
