In this session, environmental ethics is discussed as a crucial issue in business ethics that goes beyond purely economic considerations, focusing on two main sources of environmental degradation: pollution and resource depletion. Pollution—including air, water, and soil pollution—is explained as an unintended consequence of production and consumption activities that has serious impacts on human health, ecosystems, and future generations, particularly through global warming and ozone layer depletion. In addition, resource depletion includes the loss of biodiversity, excessive dependence on fossil fuels, and the increasing scarcity of critical minerals. The session also examines ethical perspectives such as deep ecology, which emphasizes the intrinsic value of the environment, as well as utilitarian and justice-based approaches that highlight market inefficiencies arising from social costs of pollution that are not reflected in market prices. Ultimately, it is emphasized that markets do not naturally protect the interests of future generations, making active government intervention, public policy, and corporate responsibility essential to ensure resource conservation and environmental sustainability.
