Politics is the art of making good decisions on insufficientevidence.LORD KENNETThis chapter discusses how we can use politics to promoteenvironmental quality <strong>and</strong> sustainability. It addressesthe following questions:■■■■■■What major environmental <strong>and</strong> political challengesdo we face in this century?How do democracies work, <strong>and</strong> what factorshinder the ability of democracies to deal withenvironmental problems?How do we influence, develop, <strong>and</strong> implementenvironmental policy?What is the role of environmental law in dealingwith environmental problems?What are the major types <strong>and</strong> roles of environmentalgroups <strong>and</strong> their opponents?What types of global environmental policies <strong>and</strong>treaties exist, <strong>and</strong> how might they be improved?27-1 ENVIRONMENTALAND POLITICAL CHALLENGESFOR THIS CENTURYWhat Changes in <strong>Environmental</strong> Awareness<strong>and</strong> Focus Have Taken Place: Some MajorShiftsThere have been seven shifts in the way we view<strong>and</strong> deal with environmental problems.This chapter examines the strengths <strong>and</strong> weaknessesof political systems in dealing environmental problems.Before doing this we need to underst<strong>and</strong> the natureof the environmental problems we face in terms ofnations <strong>and</strong> the international community of nations.Since the 1970s there have been seven shifts in thetypes <strong>and</strong> focus of the environmental problems weface. One is increasing concern about the harmful effectsof human activities on biodiversity <strong>and</strong> other forms of naturalcapital that support all life <strong>and</strong> economies. This isleading to increased emphasis on protecting <strong>and</strong>restoring entire ecosystems instead of focusing primarilyon keeping individual species from becomingprematurely extinct. To be effective this will require internationalcooperative efforts.A second is a shift from local to regional <strong>and</strong> globalconcerns about emissions of air <strong>and</strong> water pollutantsthat can be transported from one region or country toanother. One example is a significant increase in emissionsof sulfur <strong>and</strong> nitrogen compounds, especially inAsia, that can blanket large regions with smog <strong>and</strong>harmful <strong>and</strong> acid forming chemicals. Another exampleis rising levels of carbon dioxide in the atmospherefrom burning fossil fuels <strong>and</strong> clearing forests that canaffect regional <strong>and</strong> global climate patterns. A third exampleis rising levels of nitrogen compounds in the atmosphere<strong>and</strong> aquatic systems because of emissions ofgaseous nitrogen compounds by power plants <strong>and</strong>motor vehicles <strong>and</strong> rapidly growing runoff of nitrogenfertilizers from cropl<strong>and</strong> <strong>and</strong> urban l<strong>and</strong> into rivers,lakes, <strong>and</strong> coastal waters.A third shift involves growing concern over thethreat of climate change <strong>and</strong> its potential to disrupt ecological,economic, <strong>and</strong> political systems. Many analystsconsider this threat <strong>and</strong> the related problem of biodiversityloss to be the two most important environmentalproblems we face.A four shift is a growing awareness of the pollutionproblems of developing countries—especially those in theheavily populated urban areas of China, India, Mexico,<strong>and</strong> Brazil—that are undergoing rapid industrialization<strong>and</strong> economic growth. Many people in thesecountries now have some of the world’s highest levelsof exposure to tiny particles in indoor <strong>and</strong> outdoor air,lead (mostly from burning leaded gasoline), <strong>and</strong> exposureto infectious organisms in drinking water. A fifth<strong>and</strong> related shift is a growing awareness of the harmful effectsof poverty on the environment <strong>and</strong> human health (p. 13).Sixth is increasing concern about possible effects oftrace amounts of some synthetic organic (carbon-based)chemicals on human health <strong>and</strong> wildlife. Examples arepesticides, plastics, industrial chemicals, drugs, <strong>and</strong>food additives. We know little about the potentiallyharmful environmental <strong>and</strong> health effects of traceamounts of such chemicals.So far our approach has been to assume that suchchemicals are innocent until shown to be harmful.Now there is a shift, led by the European Union, tohave nations <strong>and</strong> the international community assumethat such chemicals are potentially harmful untilshown to be harmless. This leads to increased emphasison preventing pollutants from reaching the environmentinstead of trying to clean them up after theyhave been dispersed into the environment.The seventh shift involves relying more on the internationalcommunity to deal with environmental problems inan increasingly globalized world <strong>and</strong> economy. So far wehave not been very effective in bringing about this importantshift.In the 1970s the United States led the world in recognizing<strong>and</strong> dealing with local <strong>and</strong> national environmentalproblems. However, since then it has given upa leadership position in dealing with the increasinglyurgent regional <strong>and</strong> global environmental problemswe face. <strong>Environmental</strong> leadership is now comingmostly from the nations of the European Union. However,major nations such as the United States, China,<strong>and</strong> India will have to assume leadership positions forglobal environmental efforts to succeed. This will requirecooperative efforts among government, busi-606 CHAPTER 27 Politics, Environment, <strong>and</strong> <strong>Sustainability</strong>
