What is the main difference between animal welfare and animal rights?

The distinction between animal welfare and animal rights primarily revolves around the ethical frameworks they promote regarding human interaction with animals. The core of animal rights advocates for the idea that animals possess intrinsic rights, which includes the belief that they should not be used by humans for any purpose, including companionship, food, or research. This perspective argues that all animal use is exploitative and should be prohibited.

On the other hand, animal welfare focuses on the humane treatment of animals that are used by humans. This perspective acknowledges that while animals may be utilized for various purposes, they should be treated with respect and care, and their well-being should be prioritized in terms of nutrition, housing, and medical care. Thus, practices that ensure humane treatment are aligned with animal welfare principles.

By understanding this distinction, it becomes clear why the correct answer highlights that animal rights prohibits all human use while animal welfare permits and advocates for humane treatment of animals. This difference is crucial for discussions in agricultural biotechnology and ethics, influencing policies and practices regarding animal use in research, farming, and companionship.
