Here is a short note for our readers that use the bookmarking service StumbleUpon.
If you go to http://stumbleupon.com/earthday/ and "thumb up" that page you will help to plant trees, for free.
Every time a StumbleUpon user "thumbs" up that page a tree will be planted with help from the National Forest Foundation. This event will end on May 2, so hurry up and â€œthumb upâ€.
This is a pretty neat idea and in some way similar to Green Blogâ€™s own tree planting program (Sorry! I just had too..).
