"Essentially non-existent before the advent of mechanized transport, roadkill is associated with increasing automobile speed in the early 20th century. A contemporary observer, naturalist Joseph Grinnell, noted in 1920 that 'This [roadkill] is a relatively new source of fatality; and if one were to estimate the entire mileage of such roads in the state [California], the mortality must mount into the hundreds and perhaps thousands every 24 hours.'... The development of roads affects wildlife by altering and isolating habitat and populations, deterring the movement of wildlife, and resulting in extensive wildlife mortality. One writer states that 'our insulated industrialized culture keeps us disconnected from life beyond our windshields.' " Roadkill - Wikipedia
