Sure but so what. It is a question of how sustainable. Cutting 2x4s from pine trees still use a lot of non-sustainable energy sources. Saws burn gas and so do the trucks of the people who cut them down, so do the trucks that hall the logs, so do the mills that cut them, and so on and so on. There are always more externalities we don't consider. To me, the question is whether bamboo worse than other composite wood products. Does it store more carbon? Does it store the same carbon but more quickly? Can it grow using less land? Does it last longer than what would be used instead? If it is at least neutral on all the other questions, does it have other properties that make it preferable?
