Here is a NYT article regarding a proposed nutritional label that has an overall score based in part on "WELFARE A measure of the impact of the food’s production on the overall welfare of everything involved: laborers, animals, land, water, air, etc. This rating also accounts for carbon footprint and chemical (pesticide, for example) and drug (like antibiotic) residues."
Is there no place left that we can be free from being "force fed" someone's agenda? A food label should inform someone about the basics of NUTRITION, not their view of what is beneficial for migrant workers or global warming. I'll tell you this, if I want to eat a steak, I will and plenty of it, "carbon footprint" be damned.
Here is a link to the article and a pic of part of the proposed label.
