Which selection best supports the central idea that animal experimentation is unnecessary? Experimentation on animals is cruel and unnecessary. It is wrong to test drugs and products on animals. Just because animals cannot speak, it does not mean they do not feel any pain or discomfort. Also, there is no guarantee that what is safe for animals will be safe for humans. However, these experiments still continue. In today’s world, where science has come so far in what it can do, there has to be a better way to test products. One promising new method involves testing on cells in labs rather than testing on living, breathing animals.
