A very fun stuff– Bamboo bike!! You grow bamboos and you can then make these bikes on your own
-Bamboo is the fastest growing plant on Earth (Certain species have been known to grow over 4 feet in 24 hours)
-Bamboo can be continuously re-harvested. During regeneration, the roots stay intact so erosion is prevented. Continuous harvesting actually improves the overall health of the plant.
-Bamboo grows on every continent and can be harvested and used locally. With no need to ship materials, it’s a low impact building material.
-Bamboo produces up to 35% more oxygen than hardwood trees and absorbs four times as much carbon
-Owing to its high nitrogen consumption, growing Bamboo can detoxify wastewater and improve soil quality
