3. 1.1 The Nature of Environmental Science
Environmental science includes scientific and social aspects of human impact on the world.
It is a mixture of traditional science, individual and societal values, and political awareness.

4. 1.1 The Nature of Environmental Science
Environment is everything that affects an organism during its lifetime.

5. Interrelatedness Is a Core Concept
The study of environmental science is so interesting, frustrating, and challenging because of the interrelatedness among seeming unrelated factors.
Tug on anything at all and you’ll find it connected to everything else in the universe.
John Muir

6. 1.2 Emerging Global Issues
Some of the most pressing global issues are environmental change and sustainable development
Environmental change threatens people’s health, physical security, material needs, and social cohesion.
The World Commission on Environment and Development concluded 25 years ago that “humanity has the ability to make development sustainable.”

7. 1.2 Emerging Global Issues
Most social and political decisions are made with respect to political jurisdictions.
Environmental problems do not necessarily coincide with these artificial boundaries.
Air pollution generated in China affects air quality in western coastal states in the United States and in British Columbia, Canada.

8. 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.

9. 1.3 Human Well-Being and the Environment
The goal 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.

10. 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
Includes the cultural importance that environment has for life satisfaction.
What people are able to be and to do.
This focuses on what the environment allows individuals to be and to do.

11. 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.

12. 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

13. 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.

14. Environment and Globalization
In 1997, representatives from 125 nations met in Kyoto, Japan for the Third Conference of the United Nations Framework Convention on Climate Change.
The Kyoto Protocol is viewed as one of the most important steps to date in environmental protection and international diplomacy.
