Environmental ethics examines the moral basis for environmental protection and humanity's relationship with the natural world. It addresses questions about the environmental damage caused by the current generation and what values must be compromised to reduce such harm. Key issues include pollution of air, water, and land as well as depletion of natural resources and biodiversity. Ethical values for pollution control recognize our duty to protect both human and non-human welfare while using non-human resources only to satisfy vital needs. Business can play preventive, curative, and awareness roles to minimize environmental damage and educate the public on protection efforts. Overall, environmental ethics calls for respecting nature, maintaining harmony with other species, taking responsibility for impacts, and considering long-term sustainability.
