The pet trade refers to the buying and selling of animals for companionship. This industry includes a wide variety of pets, such as dogs, cats, birds, reptiles, and small mammals. Many pets are bred in captivity, while others are captured from the wild. The trade can provide people with beloved companions, but it also raises concerns about animal welfare and conservation. Regulations vary by country regarding the pet trade, with some places enforcing strict laws to protect endangered species. Organizations like the World Wildlife Fund and the Humane Society work to promote responsible pet ownership and discourage illegal wildlife trafficking.
