Tomorrow's Earth by David Bellamy. Being me, I read the book cover to cover many times over, and the trees won me over. I was 12 then.
But enough about the brief history of the shady origins of my love for trees. The fact is, I just found out today from Nick at Anything Goes that you can actually name a tree after your blog, through a tree planting program called "My blog is Carbon Neutral" and the best part is, the trees are real ones, breathing, transpiring, chlorophyll laden ones! And despite the fact that the tree is going to be planted in Plumas, California, and I am here, it still excites me. I now have a valid reason to visit California if I ever wanted to.
The process is fairly simple, I guess... just do a short write up about the program, e-mail them your link at CO2-neutral(at)kaufda.de, and pick a button for your site. Besides having a new post on your blog, you also contribute to the happiness of your blog (after all, which blog wouldn't be proud to have a tree named after them???), and reduce the carbon footprint your blog produces, especially if you have 15,000 visitors a month (I'm nowhere near that, though... I average 400 to 500 visits per month at the moment but still)
