All animals, including humans, absorb oxygen (02) and exhale Carbon (CO2).
Plants breathe in CO2 and exhale O2. In this way plants and animals have a system of mutual benefit and dependence on each other.
When a plant breathes in CO2 and exhales O2, the plant takes the C-carbon atom and converts it into plant matter through photosynthesis, storing the carbon in the plant. When the plant dies and decays, the carbon is eaten by bacteria or insects and is released back into the atmosphere as CO2.
This is how a wooden house becomes a carbon capture and storage system. Planted trees sequester CO2 from the atmosphere and the house acts as a carbon sink, storing the carbon in the beams, rafters, plywood, siding, and flooring. The same is true for BAMBOO, paper, cotton/linen clothes and all goods made from plant matter.
The advantage to building with BAMBOO is that Bamboo is rapidly renewable; it matures in just 3 - 5 years, compared to up to 60 years for hardwoods.
Bamboo purifies the water.
Bamboo provided the first re-greening in Hiroshima after the atomic blast, and was the first plant to regenerate in Vietnam after vast areas were defoliated by Agent Orange.
