I've heard this conspiracy theory before and googling it's just that Bamboo skate company that came up with it. Sounds like bullshit, all the other science articles about deforestation have no mention of skateboard production. Where is that Science Channel report? Because none of Bamboo's links take you to any report when they reference it.
Here is their calculation, if anyone is good at math maybe you can see some miscalculations?
Mature Canadian Maple trees can be up to 90 feet in height and have a trunk of about 4 feet in diameter. The volume (V=pi*r^2*h) is equal to (2ft^2)*Pi*90ft. This comes to a volume of 1,130.4 cubic feet. The dimensions of a typical skateboard are 31� long x 8� wide x �� thick. The volume comes to 124 cubic feet per skateboard. That means each maple tree makes about 9 skateboards (1130.4ft^3/124ft^3=9 skateboards).
The number of skateboard decks sold in 2004 was 5.3 million. If all of these skateboards were made from 100% maple about 588,889 Maple trees would have to be used (5.3 million skateboards/9 skateboards per maple tree= 588,889 Maples). Bamboo Sk8 only uses 30% maple in their decks. So multiply the number of trees by 70% to find out how many maple trees would be saved if every deck were a bamboo sk8 deck. (588,889 Maples x 0.70=412,222). 412,222 Maples would be saved.
http://users.humboldt.edu/rwilliams/project_williams.htmlI think 9 skateboards per maple tree is bullshit. Skateboards are 7ply, a ply is pretty much 2d and doesn't have volume? Correct? So you could calculate it that way, how many plys are in a Maple tree? If so then Bamboo's calculation is totally flawed. They don't even say what equation they used to calculate the volume of a skateboard, not sure what you would use, volume of a rectangle?
There's no source for the 5.3 million skateboards sold in 2004, that sounds way too high too, unless it's worldwide, includes long boards? It's all bunk. Fuck that disinformation.
Edit: Just figured it out, skateboard dimension is in inches, they are using feet, wrong right there. 124 cubic feet, is 927 gallons, a skateboard is no way 927 gallons. 124 cubic feet is more like a small outdoor shed or walk in closet.
