14.1. We Cannot Go On Like This
The Ehrlich/Simon debate
Common sense says that we will run out of resources
Past civilizations have declined because of exhausted resources

SustainabilitySustainability simply means living in ways that do not deplete Earth’s vital support systems
The great challenges to sustainability are
(1) Population growth beyond Earth’s carrying capacity
(2) Potentially disruptive changes in global climate
(3) Provision of adequate food
(4) Depletion of Earth’s resources
(5) Adequate supply of sustainable energy
(6) Contamination of Earth’s environment with toxic and persistent substances

The Ten Commandments of Sustainability
![Page 5: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/5.jpg)
Commandment 1
Human welfare must be measured in terms of quality of life, not just acquisition of material demands, which demands that economics, governmental systems, creeds, and personal life styles must consider environment and sustainability
![Page 6: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/6.jpg)
Commandment 2
Given that the burden upon Earth’s support system is the product of the number of people times demand per person, it is essential to address both numbers of people on Earth and the demand each puts on Earth’s resources
Burden = (Number of people) x (Demand per person)

Commandment 3
Given that even at the risk of global catastrophe, technology will be used in attempts to meet human needs, it is essential to acknowledge the anthrosphere as one of the five basic spheres of the environment and to design and operate it with a goal of zero environmental impact and maximum sustainability
![Page 9: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/9.jpg)
Components of the Anthrosphere

Commandment 4
Given that energy is a key to sustainability, the development of efficiently-used, adundant sources of energy that have little or no environmental impact is essential
![Page 11: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/11.jpg)
Commandment 5
Climate conducive to life on Earth must be maintained and acceptable means must be found to deal with climate changes that inevitably occur
![Page 12: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/12.jpg)
Dealing With Climate Change
• Relocation of agricultural production from drought-plagued areas to those made more hospitable to crops by global warming (in the Northern Hemisphere agricultural areas are likely to shift northward)
• Massive irrigation projects to compensate for drought
• Development of heat-resistant, drought-resistant crops
• Relocation of populations from low-lying coastal areas flooded by rising sea levels caused by melted ice and expansion due to warming of ocean water
• Construction of sea walls and other structures to compensate for rising sea levels
• Water desalination plants to compensate for reduced precipitation in some areas

Commandment 6
Earth’s capacity for biological and food productivity must be maintained and enhanced, considering all five environmental spheres
![Page 14: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/14.jpg)
Commandment 7Material demand must be drastically reduced; materials must come from renewable sources, be recyclable and, if discarded to the environment, be degradable
![Page 15: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/15.jpg)
Commandment 8
The production and use of toxic, dangerous, persistent substances should be minimized and such substances should not be released to the environment; any wastes disposed to disposal sites should be converted to nonhazardous forms
![Page 16: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/16.jpg)
Commandment 9
It must be acknowledged that there are risks in taking no risks
![Page 17: CHAPTER 14 The Ten Commandments of Sustainability From Green Chemistry and the Ten Commandments of Sustainability, Stanley E. Manahan, ChemChar Research,](https://reader033.fdocuments.net/reader033/viewer/2022050809/56649da65503460f94a916e8/html5/thumbnails/17.jpg)
