Optimism on Environmental Issues

The poll also found noticeable optimism on environmental issues among the American public. Seventy-two percent of the poll’s 2,605 respondents believe their personal actions are significant to the health of the environment.

And although only 42 percent of U.S. adults were initially familiar with the phrase “environmental sustainability,” two-thirds believe that it is possible to live in an environmentally sustainable way.

The phrase "environmental sustainability" was more familiar to younger poll respondents than older ones. More than 45 percent of those age 18-43 understood the term's meaning, while only 30 percent of those aged 63 and older knew the term.
