The top ten should also be somewhat durable, to the extent that a criterion, as simple as it sounds, is often my first decision: Does a material make it onto the list of healthy materials or not?

I consider whether I would bury this building material in my garden and grow my tomatoes on it. This is still the case with materials like flax fabric tape, used, for example, under high-quality upholstered furniture, where this pure natural product is used to produce extremely durable fabrics that I would have no problem saying: Buried in the garden, I believe the tomatoes would taste better and grow well on it.
