I'm part of that 80%, including whether or not something is organic.
I would very much like to have the DNA of what I eat put on the label. In college my brother took part in an experiment where they bought a lot of fish from local supermarkets, tested the DNA of everything, and over a third of the fish was, genetically, a different species than what the stores claimed them to be
That is crazy, and it's why I do not ever trust businesses to make ALL decisions. I feel I definitely have a right to know what I am eating. At the local Giant Eagle the price of salmon, e.g., really varies - there's salmon here and salmon there. That's evidently "salmon" and "mystery salmon."
