Animals bring great benefits to our lives. However, there is still disagreement as to whether animals can be used to gain benefits. In my view, I partially agree with this statement. The reasons are two-fold. The exploitation of animals is accepted for several reasons. Firstly, the human is the most important being on the Earth and everything must be done to ensure human survival. Therefore, researchers are doing the experiment on animals to find cures or vaccines for diseases to save ours. Secondly, some animals such as pigs, goats, chickens.... are nutritious food resources for people's health. Besides, their meats are one of the main products which can be exported to many countries all around the world. Therefore, our country makes a huge amount of money from selling meat products and develop its economy. All of these are morally acceptable. However, some hunters kill rare animals for fur, foods, even heart which makes them become extinct. Moreover, they are kept in cages for recreational pleasure. Furthermore, a substantial amount of animals research is done for cosmetics which is not necessary. These actions are unjustifiable. In sum, being a human, we should make use of the advantages that animals bring wisely instead of using them in a cruel and wrong way. Moreover, the animals deserve protection or else they will be in threat of becoming extinction.
