PS: If this is a typical day on planet earth, humans will add fifteen million 
tons of carbon to the atmosphere, destroy 115 square miles of tropical 
rainforest, create seventy-two miles of desert, eliminate between forty to one 
hundred species, erode seventy-one million tons of topsoil, add 2,700 tons of 
CFCs to the stratosphere, and increase their population by 263,000
