Illegal breeding refers to the unauthorized or unethical practice of breeding animals, often for profit. This can include breeding without proper licenses, violating animal welfare laws, or breeding endangered species. Such practices can lead to overpopulation, health issues in animals, and contribute to the decline of certain species. Many illegal breeding operations prioritize profit over the well-being of the animals involved. This can result in poor living conditions, lack of veterinary care, and the spread of genetic disorders. Organizations like the Humane Society and World Wildlife Fund work to combat illegal breeding and promote responsible animal care.
