Yes, the mind get lost in the zeroes. My suggestion for future communication: A modern railroad freight car will hold 100 tons.  We know what a freight car looks like, and can visualize one million of them, or  even better 10,000 trains of 100 cars each.  Comparison could also be made to the amount of rock excavated for the recent Panama Canal expansion.  130,000,000 cubic meters of rock and soil will be removed for that job, so someone else can to the math and metric conversion.  At lest it provides a basis for comparison ," (fill in percentage) of the recent Panama Canal expansion."

In the same spirit, statements by WFS, BLM or the National Park Service along the lines that 640,000 acres have been burned are not much use when most of the population is far removed from agriculture and does not know what an acre is.   A statement that 1000 square miles have been burned is within the grasp of most of our population.
