It is true that we should consider the nutritional content, environmental impact, and ethical implications of foods before making a decision. But let's not forget the important point that Nikhil made in his original essay: we can't do that if we don't first understand the production of milk and eggs! In fact, learning about the production of milk and eggs is essential in order to truly make an informed decision about what to eat. Knowing the details of how milk is produced, for example, could help us make decisions about what type of milk to buy and what types to avoid. We simply cannot look at the nutritional content, environmental impact, and ethical implications of milk and eggs in a vacuum; we must first equip ourselves with knowledge of the production process.
Furthermore, Nikhil was quite accurate when he said that we should not hide behind ignorance. We can only be truly informed about our food choices if we are willing to learn about how that food is produced. It is irresponsible to make decisions without first learning the necessary information--we must educate ourselves before making decisions. Taking the time to consider ethical issues without first understanding the production process is not enough; it is foolhardy to rely on incomplete information when making food decisions.
In conclusion, Nikhil's original essay was right on point--it is absolutely necessary to take the time to learn about the production of milk and eggs before making a decision. Otherwise, urrong as eggs would have it, we won't have all the information that we need to make a well-informed choice!
