People pay a huge price to switch from daylight saving time.
The change from fall to standard time corresponds to the mean Deer-car collisions increased by 16% In the United States, scientists on November 2 Current BiologyThe researchers estimate that eliminating this switch could save nearly 37,000 deer and 33 human lives.
In a typical year, there are more than 2 million deer-vehicle collisions—about 7 percent of all vehicle crashes. To see how much the biannual timing changes affect those numbers, wildlife biologist Laura Prugh and colleagues compiled data from 23 states that tracked crashes Whether the incident involved animals and when the crash occurred. The team compared the numbers with traffic in each state between 2013 and 2019, focusing on the weeks before and after the switch to daylight saving time in the spring and the weeks before and after the return to standard time in the fall.
Jumping forward had little effect, but on average nearly 10 percent of deer collisions each year occurred around the fallback—when the bulk of foot traffic shifts to after dark. The problem is especially acute on the East Coast. “look [a] The peak in the fall is very steep,” said Prue of the University of Washington in Seattle. “In the western states, you also see increases, but not as much. On the East Coast, the fall switch falls in the middle of white-tailed deer mating season. Not only are more drivers active after dark, there are more deer. “The timing couldn’t have been worse.” “
Eliminating the clock shift doesn’t completely eliminate the peak of the crash — no matter when sunset occurs, mating season plays a big role. But scientists estimate that maintaining daylight saving time year-round will reduce the total number of deer-human collisions by about 2 percent — saving dozens of people, thousands of injuries and tens of thousands of deer.it is another reason Let us all go to the light (SN: March 31, 2014).
