If you can grow the straw to build your own home in a season, why don’t we use straw bale building more?

What are the advantages/disadvantages of this method of building?

Any good websites?
Straw Bale Building is also Permaculture because:

You are auto sufficient in your own building materials: You grow the materials on your own land so there is less environmental damage/input: transport, mining, etc.

Straw and Mud are collected from homestead and the whole building will be returned to the homestead eventually. It uses natural materials that will return without trace when the building is no longer needed. Limits your personal environmental impact.

Whereas bricks production has many environmental costs including production, transport, environmental impact, CO2 production etc.

Relies on self reliance: The homesteader does not require special skills.

Resource use: It is using, a byproduct: ie an otherwise unused resource. Each resource should be used for as many functions within a system.
