The gap between the consumer buying food and the origins is too disconnected. People buy products from the supermarket shelves often without fully understanding the process involved in bringing meat to their plates. Every sale of meat is derived from ending the life of a living, breathing creature, who had no chance of escape, was imprisoned all their life & simply exploited in order to drive profits. This process seems significant enough to ensure the consumer understands;

a) an animal's life was ended against it's will, and significantly early in order to "produce" the meat

b) how the animal was killed, and how it was raised 

c) what the animal looked like, by representation of an image

In addition, the following points should also be considered to create transparency and knowledge in consumer choice.

d) any detrimental & scientifically proven risks from eating too much meat (e.g. processed/red)

e) clearer indication of how drastic the environmental impact of meat is compared to other food stuffs.

In the same way that food labelling laws ensure consumers are aware of the ingredients in their items. They should be made aware how these "ingredients" came to pass.

The main aim here is to create transparency & knowledge, and reinforce that the consumer understands they are directly taking the life of another creature by making their purchase, and if possible that there are countless - and healthier - alternatives available which don't directly involve the suffering or death of an animal.
