Thought I might as well put in my two cents worth on the vinyl aspect of this thread.
Problems associated with toxicity in humans will require one of the following;ingestion, inhalation, absorption or injection of a toxin into the body. One of these must take place before there is a problem with human health risks.
So, if you work at a factory or manufacturer where you are exposed to heavy concentrations of toxins and they enter your body through one of the above methods you are at risk.
If you are exposed to toxic materials
without toxins entering your body common sense would indicate no risk of negative health effects.
Consider closely the information above when determining the risk of building materials and how they may affect you or your family.
- Are you eating/ingesting it?
- Are you absorbing it through your skin?
- Are you breathing it (off gassing)?
- Are you injecting it into your body?
Chances are none of the above will be true. However if you have a small child who will be chewing on most everything then they will need proper supervision/protection no mater what type of home you live in.
GMO's in our daily diet are a far greater health and environmental risk than vinyl in our homes.
Learn more about GMO's here. BPA is still found in many food and beverage products and unless you are fanatical about looking and avoiding them then chances are you consume this and it is far more of a health risk than vinyl in a yurt.
As for the overall environmental impacts we should avoid continued production of bad stuff. Going down this same line if we can reuse, recycle and make the most out of our natural and existing man made resources this is a step in the right direction.
I myself use recycled vinyl and feel good about it. I do not believe it is a health risk because under normal use it does not enter the human body very easily. I do not promote the continued manufacture of more bad stuff and consider what I do both politically and environmentally correct.
My goal as a yurt manufacture is to provide an affordable cost effective environmentally friendly alternative to traditional housing.
Change will be slow and we must take steps to move closer to doing the right thing. This might seem like a small step but non the less it is a move in the right direction.
Fear should not be part of the process of using good judgment.
Using recycled vinyl is one solution to the problem. Keep in mind if you are not part of the solution then you are part of the problem.
