Environmental science Interrelatedness Is a Core Concept   Tug on anything at all and you’ll find it connected to everything else in the universe. John Muir Interrelatedness Is a Core Concept   Charles Darwin proposed that seed production in red clover was related to the number of cats in the area. 2 Interrelatedness Is a Core Concept   The reintroduction of wolves to Yellowstone National Park has resulted in many changes.   31 wolves were introduced in 1995.   In 1996 there were about 320 wolves.

An Ecosystem Approach   An ecosystem is a region in which the organisms and the physical environment form an interacting unit. 3 Emerging Global Issues   Environmental change threatens people’s health, physical security, material needs, and social cohesion. Environmental Governance   Development strategies need to maintain the ecosystem needs on which long-term development goals depend. •  Hurricane Katrina in 2005 demonstrated the link between destruction of coastal wetlands and vulnerability to storms. Environmental Governance   Most social and political decisions are made with respect to political jurisdictions, but environmental problems do not necessarily coincide with these artificial human made political boundaries. •  Air pollution generated in China affects air quality in western coastal states in the United States and in British Columbia, Canada. •  Air pollution generated in Juarez, Mexico, causes problems in the neighboring city of EI Paso, Texas 4 Environmental Governance   Eight U.S. states, two Canadian provinces, and hundreds of local jurisdictions impact environmental decisions in the Great Lakes on pollution, exotic species, fishing, and land use. Human Well-Being and the Environment   The end point of development is human well- being.   Human well-being and the quality of the environment are strongly interrelated. •  Environmental changes have impacts on human wellbeing. Defining Human Well-Being   Resources people have, such as money and other assets. The environment is seen only as a means to promote economic growth.   How people feel about their lives, including the cultural importance that environment has for life satisfaction.   What people are able to be and to do. This multidimensional view focuses on what the environment allows individuals to be and to do. 5 Project Get Outdoors   Nature deficit disorder    Project GO was developed in response to Richard Louv’s 2005 book, “Last Child in the Woods; Saving Our Children from Nature- Deficit Disorder”.  Defining Human Well-Being   Ecosystem services include •  Provisioning services: food, water •  Regulating services: flood control, disease control •  Cultural services: spiritual, recreational, and cultural benefits •  Supporting services: nutrient cycling   The world’s poorest people depend primarily on environmental goods and services for their livelihoods. Karst Topography 6 Karst Topography Environment and Health   The World Health Organization estimates that 13 million deaths worldwide could be prevented every year by environmental improvement. •  Cancer •  Malaria •  Coronary Heart Disease •  Diarrhea Environment and Health   Urban air pollution affects health in almost every region of the world. 7 Environment and Security   Security means having stable and reliable access to resources and the ability to be secure from natural and human disasters.   Scarcity of water or other resources can lead to armed conflicts.
