I just read in the newspaper that FEMA is in trouble again,
...this time because all those camping trailers they put people in after Hurricane Katrina are turning out to be poisonous to live in. Formaldahyde, mostly, yes.
I've been reading several magazines over the last few years, trying to learn. You might take a look at Natural Home, Smart Homeowner, Mother Earth News, EcoLogical Home Ideas and so forth. I bet you can find a lot of info on their web sites.
In a nut shell: I've learned very little, because all this "green" business is so complicated, and sometimes even conflicting. A science in its infancy. But some things are clear enough, like "sniffing glue is not good", so you avoid materials that consist of "sawdust and glue".
