Thus, animal testing must be banned. …show more content…
This previous claim is not completely true because 90% of experiments on animals show positive outcomes, which means that the meant substance is safe for human usage, while it is not (2). For example, thalidomide which is known as the most failed example of animal tests in the 1960s and 1950s (3). A thalidomide medication caused many tragedies worldwide after its utilization as a treatment of morning illness in pregnancy (3).
