Farmers, pet and animal owners, and scientific researchers have many different ways of treating animals in their care. Fewer than 30% of countries have animal welfare laws, and existing laws are not always enforced. Researchers assert that it is important to be able to use animals in research to test drugs and new medical procedures that can help both people and animals. Sometimes endangered animals are kept in captivity at a high cost in order to protect their limited populations. Animal shelters are often filled with feral animals or those that have been abandoned by their owners. Wild animals in many parts of the world come into conflict with human activity.
In the future, how might research impact human understanding and treatment of animals? Are zoos useful educational tools or unethical exhibitions? Are certain animals entitled to more rights than others based on cultural or intelligence differences? How can humans be better stewards in the treatment of animals? Who decides the appropriate treatment of animals and their role in society?
