More than 100 million animals die due to being tested on each year. This is just in the United States, so the number can be much higher when other countries are included in this number. The causes of death vary greatly, depending on the animal, where they’re being tested on, and what they’re being tested on for.
Some will starve to death. Others are beaten or exposed to plenty of toxic fumes before dying. Some even due to the stress of what they’re going through as part of being tested on. Most of the deaths could be avoided if these companies didn’t test on animals since a lot of areas are now banning animal testing for products to be sold in those countries.
