The graph below shows that between 1980 and 2007, gross domestic product increased 124 percent, vehicle miles traveled increased 103 percent, energy consumption increased 30 percent, and U.S. population grew by 33 percent. During the same time period, total emissions of the six principal air pollutants dropped by 52 percent.And prof Mark Perry on Carpe Diem charts other EPA data on "particulate matter" (PM), which "show that average PM concentrations have decreased over the years by -28% since 1990 for the first measure (PM10) and by -11% since 2000 for the second measure (PM2.5)."

Or that Western Civ. is transforming the Earth (atmospheric CO2 380 parts per million) into Venus (970,000 parts per million). For "TOOTSIFs," the sky forever is falling.
