I thought Bamboo was the fastest growing tree? I remember it grows more than an inch every hour. Since no one has done mass planting of Bamboo, there must be some down fall that wasn't well known? Edit: Turns out Bamboo is classified as plant. But the question remains the same.
> Bamboo’s carbon sequestration properties have been studied in countries where it naturally forms wild forests, such as Mexico (Castañeda, 2006) and China (Song, 2011). Contributing to these efforts, Ricardo Rojas Quiroga—an environmental engineering student at the Universidad Nuestra Señora de La Paz—studied Guadua angustifolia, a species of bamboo that grows in the Carrasco National Park of Bolivia. He measured the density and masses of bamboo plants in the forest, estimating the amount of carbon stored per hectare. Rojas concluded that, in addition to forming part of one of the most biodiverse ecosystems in the world, each hectare of the bamboo forest of Carrasco National Park stores levels of carbon comparable to some large tree species such as Chinese fir and oak. This finding is consistent with that of many previous studies, a review of which can be found in this 2010 report by INBAR.
