Nowadays, the usage of animals for human needs such as clothing, food and medicine are not unavoidable. In my opinion, these human necessities can not survive without animal use. However, only the production of clothing can be an exception.
Primarily, it is worth noting that some medical preparations or treatment are created thanks to animals. Snake venom can be a bright example for this case. Since venom of snakes is the active ingredient in many ointments that have analgesic, anti-inflammatory effects and can increase the blood flow. Which means that fauna plays a crucial role in medicine.
When it comes to food, I believe that animal meat has great importance in our diet. Since ancient times, it has been the main food of people due to vitamins and energy which are provided. Hence, no product can replace meat in our diet.
However, I firmly believe that clothing production can easily do without the use of animals. Today, there are variety of materials that do not require the torment of wildlife. Moreover, majority already buy clothes that do not contain animal wool due to the lower price. Because of this, I consider animal wool in clothing sphere easily replaceable.
Summing up, I do believe that fauna plays crucial role in spheres of medicine and food and should be allowed only for these cases, although fauna should not suffer by the reason of clothing production.
