Answer
The primary sinful activity described in the scriptures is animal killing.
If people are able to obtain meat without killing animals, that is certainly preferable to slaughtering them. In fact, Srila Prabhupada addressed this issue many years ago. He said that if someone is so attached to eating cow flesh, they should wait until the cow dies a natural death and then eat the flesh. In that case, they would not incur the sinful reaction of killing the cow.
Therefore, there is no real necessity to develop meat in a laboratory. Animals will naturally die in due course. If someone insists on eating meat, they should at least avoid killing the animal.
The Vedic scriptures strongly prohibit the killing of cows. Historically, if meat-eating was to be permitted at all, it was restricted to the sacrifice of a goat under very strict scriptural regulations, where the animal was offered to Goddess Kali. Such sacrifices were never intended to encourage meat-eating but to regulate and discourage it while minimizing the sinful reaction of killing.
However, even if one avoids the sin of killing, meat itself is not proper food for human beings.
In the seventeenth chapter of the Bhagavad-gita, Lord Krishna classifies food according to the three modes of material nature. Meat is categorized as food in the mode of ignorance (tamo-guna).
Krishna describes foods in the mode of ignorance as those that are stale, decomposed, putrid, tasteless, impure, or unfit for offering. Such foods increase ignorance and degrade one's consciousness.
Similarly, intoxicants are also products of the mode of ignorance.
The fourteenth chapter of the Bhagavad-gita explains the effects of the mode of ignorance. It is characterized by:
Delusion
Madness
Laziness
Excessive sleep
Ignorance
A person influenced by the mode of ignorance cannot understand reality as it is.
For example, everyone sees that previous generations have died and knows that they too must one day die. Yet, people continue to spend their lives simply accumulating wealth while neglecting the eternal soul. This is described as a symptom of ignorance.
Therefore, one should avoid foods that increase the mode of ignorance.
Even if laboratory-grown meat does not involve the direct killing of an animal, it remains meat, which belongs to the mode of ignorance and is therefore unsuitable for cultivating higher spiritual consciousness.
Human beings are endowed with higher intelligence to pursue spiritual realization. Meat is the natural food of carnivorous animals, not of those seeking spiritual advancement.
For this reason, the recommendation is simple:
Do not eat meat. Instead, honor Krishna prasadam, which purifies both the body and the consciousness.
