Cons- It harms animals.
- It is very costly. - Spending money on animal testing instead of more important things. - Killing endangered animals (such as polar bears). - Causes some humans to protest against the tests. - Animals that survive the test then have to live a life in captivity. - Believed to be unreliable, so what might work on animals may not work on humans. |
