So what's your point. We can't make everything out of earthbags, hemp, cob? Also, check your figures on what is expelled into the air for one volcano eruption. I've stated in other forums, if man quit pollution all together for an entire year, that one eruption would create more pollution and would wipe out the gains.

All of earth's volcanoes emit less than 1% of human-based CO2 annually.
For example, in 2008 humans emitted about 36 billion metric tons of CO2. In that same year, the highest estimates for all volcanoes combined (submarine volcanoes included) were just 270 million metric tons (Gerlach, 2010).
Even the European airline industry emits more CO2 than a volcano blast:
Beside particulate (ash and other particles), volcanoes can release enormous quantities of gases, including the following pollutants:
H2O water vapor
CO2 carbon dioxide
SO2 sulfur dioxide
H2S hydrogen sulfide
CO carbon monoxide
HCl hydrogen chloride
HF hydrogen flouride
I'm not against alternative building methods or materials. Again, you guys keep missing the point. It would be nice to build a new home with better greener materials however,in most cases that's impossible. That's the point. Steel requires a lot of resources and causes pollution. Wood does the same. The point is that we have to accept these losses and try to do the best we can. However, we can't crucify folks for utilizing what is readily available until other systems become more main stream and less costly.

That is the point they are available these days and at a comparable cost.
However, It's hard to find anyone that is using them and understands how to best apply the material.
Again, if they were main stream I could go to my local Home store supply and get them. I can't. So that is the point. Yes, if I make considerable efforts I can find some of these materials. However, It's hard to find anyone that is using them and understands how to best apply the material.
While that may be the point for you, it's certainly not the point for me at all. The point for me is to make the additional efforts necessary to find materials that are more ecologically (and hopefully economically) sound than what I can find in the builders' supply. If I have to call or ask around a bit to find somebody in my area to deliver a load of road base to my site, so what? It will still be miles less polluting than a comparable load of portland cement based concrete, and almost certainly less expensive to boot. If I were to limit my selection of building materials to what I could find at the local home supply store, I would have pretty much zero need (or likely desire) to read a green building message board on a permaculture forum.
Also, that a concrete house can be "CONSIDERED" green by definition as it allows the home owner to meet some of the standards for green (energy efficiency).
Spent nuclear fuel rods make an excellent shell for a house. They last forever, and they're a waste product! Combine that with 10 inches of polyurethane, and you have a durable, "green" home!
It is only "considered" green if your ignore the large environmental debt it creates during its production. It will take decades of energy savings to pay back those debts. That's not green.
We could build homes out of a lot of stuff that isn't "green", but pack it with carcinogens.... er, I mean insulation, and then slap a green label on it. Sorry, that doesn't make it green.
Never mind the environmental costs, right?
So, basically, if you hide 1/2 of the picture, it looks attractive. When you uncover that over half, however....

I think we can all agree that building a home to your local codes may require a person to use less then ideal materials. A person could choose to build in secret and risk fines, not me. For those of you lucky enough to live in a code free area, I envy you.
I would love to have a Monolithic Dome because of how indestructible it appears. However, being poor prevents this.
I will try to build an earth bag home, even if I have to call it a shed/barn/playhouse. I want to dig a pond, so the removed earth can be used to fill bags.
The only thing that I should have to import to my property are the bags, some evil plastic, and maybe another shovel.
ps. Timby we had a family at our church give us truck when our vehicle died, I almost cried (my wife did).
i dont pretend to be a purist, i love plastic sheeting, it is a awesome material in my opinion, if it is kept from sunlight it lasts a long time, maybe longer, vapor barriers are essential for a comfortable on grade or below grade dwelling and i dont know what can be found in nature to equal plastic sheeting
