TreeHugger's Top 5 Posts of 2009

The internet works in weird and wonderful ways; the strangest things rise to the top. Who would have thought that treehouses are so popular, that they would be two of the top five posts of the year? Tongue-eating parasites are no surprise at 4, but a houseplant at 5?

Number one, Treehouse by Tham & Videgard Hansson is Almost Invisible, attracted 899 comments, the first of which was "in what way is this even remotely related to sustainability? If I mirrored a Hummer would I get my project posted, too?"

2. Massive Underground Coal Fire Started in 1962 Still Burns Today chronicled a fire started in 1962 to burn trash in a dump that inadvertently spread to a coal seam underground and has simply never stopped burning.

3. Tree Houses Fit for TreeHuggers, a whole slideshow of them.

4. Who could forget the Bizarre Tongue-Eating Parasite Discovered Off the Jersey Coast. Favourite comment:

"With two daughters, I've known about tongue eating parasites for decades. They're called "boy friends."

5. Best Air-Filtering House Plants According to NASA!

First comment: "I have been waiting for an article like this!" Who knew that a list of houseplants could have such impact on the world.
