人与环境的相互作用构成了21世纪最引人注目的也是最严峻的挑战（气候变化）
Human-environment interactions pose some of the most compelling and fraught challenges of the 21st century (climate change, deforestation, water resource availability, energy consumption, urban expansion and population growth, and food security). Understanding these challenges and solving environmental problems requires both knowledge of ecological and physical processes and insight into the cultural, demographic, economic, geographical and political aspects of human-environment connections. Environmental management is therefore complex and requires interdisciplinary approaches to resolving challenges posed by human-environment interactions. Environmental management combines the social sciences and humanities with the study of physical geography, the earth sciences and biology to provide the breadth of knowledge required of environmental managers. Environmental managers work in a diverse array of roles and settings (ranging from policy-oriented to field-based positions). Employment sectors include: water resources, waste management, energy, natural resource management, land-based and coastal management, climate change, and sustainability.
