Using data provided by Gallup, I created this chart showing how Republican views of the environmental movement have changed in the past 10 years:
These results indicate that the decline in positive views of the environmental movement among Americans over the past decade is disproportionately the result of substantial declines among Republicans, which dwarf those among Democrats.
As you can see, nearly 50% of Republicans now think the environmental movement has done more harm than good, up from 28% just 10 years. And on the flipside, while 70% of Republicans thought the environmental movement did more good than harm in 2000, just 49% feel that way now.
Happy Earth Day, Republicans!
