The modern era has made it possible for many traditional products to be substituted by their modern counterparts. Therefore, it is argued that animals should no longer be the major source of meat or other commodity products because of the availability of the new replacement. From my perspective, such a view is irrational because the justification of animal products does not correlate with the so-called modernity.
Indeed, it is easy to understand why some people take it for granted that animals should no longer play an indispensable role in our diet or commodity products. From their perspective, the relentless advance of artificial products has successfully replaced many old-fashioned ones made of the substances extracted from animals. One compelling example in this trend is the wide employment of acrylic fiber as a substitute for wool in clothing industry.
This might be the case in some fields, however, I tend to say some successful cases of modern replacements are not persuasive enough to illustrate the entire picture. Those who laud the triumph of artificial products are oblivious to the fact that the justification of animal products does not hinges on how advanced the technology is. Rather, whether we should continue using animals in production is an issue of great complexity that needs to consider various determinants. Of all factors, the very problem that concerns me most is people’s preference for natural material over cheap replacement in laboratories. Let’s recur to the example of dress, compared with the synthetic chemicals, I still prefer the quality of wool or leather.
Another stronger argument against the statement in question is the apprehension of safety that might ensue should the natural ingredients from animals be replaced by chemical elements: what we cannot afford to ignore is that these materials might not marry with human bodies as well as their natural counterparts do.
In conclusion, it looks to me that there is no causal relationship between the advance of modern technology and the justification of traditional animal products.
