Hmmm, wonder why?

(CNSNews.com) – A Gallup poll released on Friday shows that the number of Americans who identify as environmentalists has dropped 36 points, from 78 percent in 1991 to 42 percent in 2016. There has also been a decline in Americans expressing concern about environmental problems, such as pollution.

The Earth Day poll is conducted annually by Gallup. The polling firm cites the politicization of environmental issues as one possible reason for the decline, highlighting the growing partisan gap in those who identify as environmentalists. […]

However, Gallup notes the “broader decline in personal environmentalism at the same time that the environment has turned into more of a Democratic than Republican issue,” citing the large decline in Democrats who consider themselves environmentalists — 56 percent today versus 78 percent 25 years ago.

Gallup also notes a decline in Americans’ concern over environmental problems, such as air pollution and pollution of rivers, lakes and reservoirs. Concern over polluted drinking water is down from 65 percent in 1989-1990 to 61 percent today.
