STAGE 1 - Resource Extraction
Harvesting and removing the resources and transportation of the material. This includes the logging or mining required to retrieve the materials, the equipment used, the building of roads to transport the materials and reforestation efforts.

Why Wood?
Harvesting wood has been shown to be much less intrusive than the mining of raw materials for steel and concrete such as iron ore, coal and limestone. And advancements in technology have even improved upon the process.
