Good idea! Like a nutritional label for electronics. The FDA is very strict about nutritional labels, as they should be.
Those labels don't mean much because companies have really worked around and lobbied to make it all a very murky label.
"Organic" labels, for instance, don't mean they haven't used pesticides or other harmful things – just a certain list of them.
