[MCN] “The death knell for the grizzly in the Southwest was tolled not by a church bell but by a train whistle.”

[Lance Olsen]

“The death knell for the grizzly in the Southwest was tolled not by a church bell but by a train whistle.”
 
“Changing economic conditions, new homesteading laws, and cheap rail travel resulted in an ever-increasing influx of settlers, who eventually penetrated to the remotest corners of the region.”
 
David E. Brown.  The Grizzlies of the Southwest. University of Oklahoma Press. 1985. p. 97

"It is solar energy that moves the rabbit, the deer, the whale, the boy on the bicycle outside my window, my pencil as I write these words."

"Only about a tenth of 1 percent of the energy received from the sun by the earth is fixed by photosynthesis .... about the equivalent to the annual production of between 150 and 200 billion tons of dry organic matter….”

"The worldwide increase of human numbers ... requires that a growing fraction of the total energy fixed be diverted to the direct support of man."

“The broad pattern of these changes is clear enough.”

Woodwell, George. "The Energy Cycle of the Biosphere.”  Scientific American. September, 1970
