Welfare Considerations

Clarity about the philosophical basis for animal moral consideration shapes both policy and personal practice. While philosophical debates continue, the growing consensus that sentient animals have morally relevant interests provides a basis for welfare improvement that does not require resolving all philosophical disputes.
