In February of this year, a pedestrian light on a crosswalk in Japan collapsed.
The useful life of the traffic light column was 50 years, but it has been 23 years, half of which, as a result of expert scientific analysis, found 40 times more animal urine than other traffic lights in the root area.
In this place, which was a trail for residents and a pet dog walking course,
dogs peed so much that corrosion was faster than imagined that it collapsed on a cold winter day.
