I've just been inspired by this post on Beth's blog to participate in this wonderful project that will plant a tree for every blogger who signs up, to neutralise the carbon dioxide emissions generated from your blog.
There are of course many ways to do your bit for the environment. This is just one of them and it's completely free. You just need to write a short blog post about the initiative, insert one of the buttons provided, send the link to your post to them and they will plant a tree. It will take you about five minutes and every tree counts. So go on, you know you want to! You'll be spreading the word to other bloggers too.
