Economists criticize opinion polls because they don't recognize tradeoffs. In other words, it is easy to say that I'm concerned about the environment but more difficult to actually do something about it (such as vote for higher taxes to pay for an improvement). Here is some evidence that even environmental attitudes incorporate this sort of tradeoff. When survey respondents feel a budget pinch their demand for environmental quality goes down:
The financial crisis made Americans less worried about climate change. The Democrats’ attempt to pass sweeping climate legislation in 2009 and 2010 probably reduced Americans’ anxiety level as well, as paradoxical as that may sound. But now Americans are getting more worried again.
About 69 percent of adults say that global warming is either a “very serious” or “somewhat serious” problem, according to a new Pew Research Center poll, up from 63 percent in 2010. The level of concern has still not returned to that of a decade ago; in 2006, 79 percent of adults called global warming serious.
It’s impossible to know exactly why concern about the climate fell — and why skepticism that global warming was real increased — starting around 2008. Both economics and politics probably play a role. The financial crisis and recession made Americans more worried about the immediate condition of the economy, rather than about the long-term condition of the planet.

Here is more systematic evidence from an abstract of a paper I handled as an associate editor at the Journal of Environmental Management:
Objective: We test whether macroeconomic conditions affect individuals' willingness to pay for environmental quality improvements.
Background: Improvements in environmental quality, like everything, come at a cost. Individuals facing difficult economic times may be less willing to make trade-offs required for improvements in environmental quality. Using somewhat different methodologies and shorter time frames, prior investigations have generally found a direct relationship between willingness to pay for environmental improvements and macroeconomic conditions.
Method: We use a nearly 40-year span (27 periods) of the General Social Survey (1974–2012) to estimate attitudes toward environmental spending while controlling for U.S. macroeconomic conditions and respondent-specific factors such as age, gender, marital status, number of children, residential location, educational attainment, personal financial condition, political party affiliation and ideology. Macroeconomic conditions include one-year lagged controls for the unemployment rate, the rate of economic growth (percentage change in real GDP), and an indicator for whether the U.S. economy was experiencing a recession.
Results: We find that, in general, when economic conditions are unfavorable (i.e., during a recession, or with higher unemployment, or lower GDP growth), respondents are more likely to believe the U.S. is spending too much on “improving and protecting the environment”. Interacting lagged macroeconomic controls with respondent's income, we find that these views are at least partially offset by the respondent's own economic condition (i.e., their own real income).
Conclusion: Our findings are consistent with the notion that environmental quality is a normal, or procyclical good, i.e., that environmental spending should rise when the economy is expanding and fall during economic contractions.
