1 Sprague ENV MATES Environmental Issues, Their Causes, and Sustainability G. Tyler Miller’s Living in the Environment MATES Chapter 1 G. Tyler Miller’s Living in the Environment MATES Chapter 1

2 Sprague ENV MATES Key Concepts  Growth and Sustainability  Resources and Resource Use  Pollution  Causes of Environmental Problems

3 Sprague ENV MATES Living More Sustainably  Ecology (Biologists)  Ecology (Biologists)  Environmental Science (Natural and social scientists study the earth, our interactions with it, and how to deal with problems.  Environmental Science (Natural and social scientists study the earth, our interactions with it, and how to deal with problems.  Sustainable Society 1.Living off interest vs. capital 2.Carrying capacity  Sustainable Society 1.Living off interest vs. capital 2.Carrying capacity

4 Sprague ENV MATES Population Growth  Exponential Growth  Doubling Time/ Rule of 70 Fig. 1-2 p. 4

5 Sprague ENV MATES Fig. 1-1 p. 2 World Population

6 Sprague ENV MATES Economic Growth  Gross National Product (GNP) (Our Total)  Gross National Product (GNP) (Our Total)  Gross Domestic Product (GDP) (Our Inside Part) value of all goods and services  Gross Domestic Product (GDP) (Our Inside Part) value of all goods and services  Gross World Product (GWP) (World Total)  Gross World Product (GWP) (World Total)  Per Capita GNP (Average)  Per Capita GNP (Average)

7 Sprague ENV MATES Economic Development  Developed Countries (US, Canada, Japan, Australia, NZ, Europe)  Developed Countries (US, Canada, Japan, Australia, NZ, Europe)  Developing Countries  Positive Aspects (Life expectancy doubled, food production outpaces population growth, more goods/less materials, pollution decline in developed countries)  Positive Aspects (Life expectancy doubled, food production outpaces population growth, more goods/less materials, pollution decline in developed countries)  Negative Aspects (Life expectancy and pollution control lag in developing countries, unsustainable natural resource use, population competing with wildlife habitats, self-inflict climate changes)  Negative Aspects (Life expectancy and pollution control lag in developing countries, unsustainable natural resource use, population competing with wildlife habitats, self-inflict climate changes)

8 Sprague ENV MATES Globalization “An interconnected world” Economic (Trade) Economic (Trade) Information and Communication (Internet) Information and Communication (Internet) Environmental Effects (Transport of species/disease) Environmental Effects (Transport of species/disease)

9 Sprague ENV MATES Resources  Perpetual  renewed continuously “SUN”  6 billion years more  Perpetual  renewed continuously “SUN”  6 billion years more  Renewable  Replenished somewhat rapidly  Renewable  Replenished somewhat rapidly  Non-renewable Fig. 1-6 p. 9

10 Sprague ENV MATES Renewable Resources  Sustainable Yield  The highest rate at which a resource can be used without reducing its available  supply  Sustainable Yield  The highest rate at which a resource can be used without reducing its available  supply  Environmental Degradation (exceeding sustainable yield) Ground water, Overgrazing, Deforestation  Environmental Degradation (exceeding sustainable yield) Ground water, Overgrazing, Deforestation  Tragedy of the Commons  Biologist Garret Hardin 1968; If I don’t use this resource someone else will  “What difference do I make?”  Tragedy of the Commons  Biologist Garret Hardin 1968; If I don’t use this resource someone else will  “What difference do I make?”

11 Free Access Resources Regulate Access To a Resource Example; FISHERIES, GRAZING LANDS, FORESTRY Or Convert to private ownership??? Sprague ENV MATES

12 Non-Renewable Resources Exist in a fixed quantity Million or so years to replenish  Energy Resources  Metallic Resources  Non-Metallic Resources  Reuse  Recycle Economic Depletion Fig. 1-7 p. 10

13 Sprague ENV MATES Ecological Footprint Humanities footprint is 15% higher than earths bio capacity

14 Sprague ENV MATES Pollution  What is pollution? (Anthropogenic vs. natural) Humans burning Coal vs. Volcanic Eruption  What is pollution? (Anthropogenic vs. natural) Humans burning Coal vs. Volcanic Eruption  Effects of Pollution Sources  Point  Nonpoint

15 Sprague ENV MATES Dealing With Pollution  Prevention (Input Control)  Eliminates the production of pollutants  Prevention (Input Control)  Eliminates the production of pollutants  Cleanup (Output Control)  As it says or dilute. The solution to pollution is dilution???  Cleanup (Output Control)  As it says or dilute. The solution to pollution is dilution???

16 Sprague ENV MATES Environmental and Resource Problems  Major Problems ( See Fig. 1-9 p. 12 )  Five Root Causes Fig p. 12

17 Sprague ENV MATES Environmental Impact Fig p. 13

18 Sprague ENV MATES Environmental Interactions WE need to understand these interaction. Fig p. 14

19 Sprague ENV MATES Environmental Worldviews CLASH!!!!  Planetary Management 1.We’re in charge, 2.There’s always more, 3.All economic growth is good, 4.Success depends on understanding, controlling, and managing the earth for our benefit.  Planetary Management 1.We’re in charge, 2.There’s always more, 3.All economic growth is good, 4.Success depends on understanding, controlling, and managing the earth for our benefit.  Environmental Wisdom 1.Nature’s in charge, 2.Some things are limited, 3.Technology and economic growth can be bad, 4.Success depends on learning how the earth adapts and integrating how nature acts in to how we act.  Environmental Wisdom 1.Nature’s in charge, 2.Some things are limited, 3.Technology and economic growth can be bad, 4.Success depends on learning how the earth adapts and integrating how nature acts in to how we act.

20 Sprague ENV MATES Environmentally-Sustainable Economic Development IDEAL!!! IF anything to do it for our future Fig p. 17 Decision making in a sustainable society Decision making in a sustainable society SocialEconomic Environmental Sustainable Solutions Traditional decision making Traditional decision making Environmental SocialEconomic
