The world has changed a lot over the past 50 years. Scientists have spent a lot of time in research, to find ways to improve the quality and ingredients of consumer items. A lot of innovation has been seen in the Food, clothing and medicine industry. In well developed countries like Australia, France and Germany people have alternatives to animal products for daily consumption items such as food, clothing and medicine. Further research on this must be held so that animal products can be completely substituted by other products. In other words, animal products are necessary for food, clothing and medicine in the modern world.
