At twenty-five, I weighed 190 pounds. Horrified, I fasted forty days over four months while walking two hours a day and lost fifty pounds, which I kept off for another fifteen years. A success story by almost any measure. This is where we as a civilization were decades ago as scientists who understood greenhouse gases and the corporate leaders who suppressed their research. The planet’s “weight,” or temperature, might have been managed at that point and kept under control.
