“…Perhaps the most straightforward approach is to ask people how worried or upset they are about a series of environmental problems, whether on the local or national level (Constantine and Hanf 1972;McEvoy 1972;Dunlap, Gale, and Rutherford 1974;Milbraith 1975). A second approach, striving for greater concreteness, asks respondents to weigh tradeoffs-sometimes implicitly, as in asking whether more or less money ought to be spent on environmental protection (Dillman and Christenson 1972;Erskine 1974;Dunlap and Dillman 1976;Lowe, Pinhey, and Grimes 1980;Mohai and Twight 1986), and at other times explicitly, asking about tradeoffs of environmental protection against increased employment or industrial development (Sharma, Kivlin, and Fliegel 1975;Marsh and Christenson 1977;Butte1 and Flinn 1976a;Mohai and Twight 1986). A third approach involves measured agreement with items that are more abstract, such as the belief that "Mankind was created to rule over the rest of nature," or that "The earth is like a spaceship with only limited room and resources" (Dunlap and Van Liere 1978, p. 13).…”
