American citizens are increasingly divided over the issue of environmental protection and seem to be taking their cue primarily from Congress, according to new research from Michigan State University. The gap between conservatives who oppose environmental protection and liberals who support it has risen drastically in the past 20 years, the study found. A national poll from 2012 (the most recent data in the study) with a question on environmental spending indicated that 68 percent of Democrats believe the country has spent too little on the environment, versus only 40 percent of Republicans. The polling data, which reach back to 1974, indicate the gap started growing particularly wide in 1992, a year after the fall of the Soviet Union. At that point, the researchers say, the conservative movement replaced the “Red Scare” with the “Green Scare” and became increasingly hostile toward environmental protection, a trend amplified in recent years by the Tea Party.
