The letter writer says, “Nothing has scared me more than looking at my child’s face with a look of hopelessness.”
Ambiguity aside (whose face had the hopeless look?), there is no reason to be hopeless. One of the great lessons learned over the last 100 years or so is that economic prosperity and environmental conservation go hand in hand. The most obvious approach to maintaining the planet as a Garden of Eden is to promote high economic growth which can pay for conservation.
It seems to me that “free” energy would drive enormous economic growth. That’s essentially what fossil fuels have been. They brought us to the point where, now, other options are feasible as a matter of science and engineering.
That’s the message the young need to hear.
