Each year, around 250 million laboratory animals are used worldwide in experiments. In the US, over 90% of research animals are rodents, and 20 to 25 million face painful procedures without adequate pain relief. The scale of animal experimentation shows how institutional practices keep producing harm even when regulations exist.
Key Takeaways
- Each year, around 250 million laboratory animals are used worldwide in experiments, including mice, rats, fish, birds, and primates.
- In the US, 3.3 million dogs and 3.2 million cats enter shelters annually, 920,000 euthanized.
- In the United States, approximately 9 billion chickens are killed for meat each year, with 99% raised in factory farms under intensive confinement.
- 50+ countries have banned or restricted animal circuses, US 10 states fully banned.
- Globally, over 100,000 elephants are poached annually for ivory, primarily in Africa.
Animal rights statistics show most cruelty is driven by factory farming, making reform and better laws urgent.
