In the 1990s, I did not believe a small concentration (equivalent to 40 cents in $1,000) could have such disastrous effects. Then in 2010, our foothills home was destroyed in the Four Mile Canyon Wildfire, and for three succeeding years, a major wildfire visited Colorado. In 2013, we experienced floods of biblical proportions. Science predicted these and other consequences. I was forced to reconsider my denial.
