Environmental management aims to prevent environmental problems through establishing limits, research, monitoring, and management institutions while sustaining and improving resources and quality of life. It considers the unexpected effects of human actions on nature and looks beyond local impacts. Environmental managers follow risk-averse strategies like working to safe standards and adopting sustainability to avoid criticism and lose of trust. Approaches to environmental management can consider systems, regions, disciplines, strategies, voluntary sectors, business needs, and political and human ecology frameworks. Population growth, consumption, and technology impact the environment, as do debates around limits to growth and different environmental ethics.
