A good book to read is THE HEALING SON. there is a glass they use to produce to allow uvb through - not any more - we should lobby for this glass.
@MrLeooreo I've never heard of that before! Thanks for the info. That would be great to allow people to have glass that would let UVB rays through so they could make vitamin D while indoors.
