Thanks to Cherees over at Our New Life, now I know. She was contacted regarding this initiative that is based by a German company. It is called Carbon Neutral. They plant a tree for every blog that supports their cause. It's as easy as that. There's no reason NOT to support them. I mean, all you have to do is put the button on your page, and then email them, and then they plant a tree. No hard work on your part.
I'm taking this a step further. For every one of my followers and friends that decides to support this cause, I'll also plant a tree. I'll start this weekend with 2 trees - one for Cherees and one for me. If you can take 10 minutes to add the button to your own blog, post about it, and then comment me, then I'll plant one for you, too. Click on my button above or in my sidebar to go to their website.
