Applied ethics is a branch of philosophy that focuses on the practical application of moral principles to real-world situations. It examines how ethical theories can guide decision-making in various fields, such as medicine, business, and law. For instance, in medical ethics, professionals must navigate complex issues like patient consent and end-of-life care, ensuring that their actions align with ethical standards. This area of study helps individuals and organizations address moral dilemmas by providing frameworks for evaluating their choices. Topics like environmental ethics and business ethics illustrate how applied ethics can influence policies and practices, promoting responsible behavior in society.
