Perhaps the environmentalists will get so worked up and worried about a problem that they actually may take a science or engineering class. And then again perhaps not.
An environmentalist that is good in science or engineering is as rare as a Senator that is a military expert.
While environmentalists lament the internal combustion engine, it was that technology that made cities more livable. When horses were the norm, literally tons of horse manure and thousands of gallons of horse urine were deposited on city streets every day breeding flies, stench and disease. Dead horses were also a major clean-up problem. The automobile changed all that for the better.
