There have been a lot of improvements in all aspects of our lives over the past decades. Ranging from the food we consume to the type of fabrics and materials we put on and so on. It is argued that, in the advanced world, individuals need not use animal products for food , for medicinal purposes and for clothes. I disagree with this argument by supporting my stance with reasons such as the nutritional value, affordability and cost-effectiveness of these animal-derived substances.
