Animal testing is a serious cause. 18.5 million animals die of animal testing each year. Animal testing is the use of animals in experiments and development projects usually to determine toxicity, dosing, and efficacy of test drugs before proceeding to human clinical trials. There are many causes to this issue which include new products being invented. The more products invented the more animals they have to test on, and unfortunately there is no consequence.There is one organization that does everything they can to try to put animal testing to an end. The PETA organization spreads awareness worldwide to stop animal abuse.
