On 10 June 2017 PBS NewsHour reported:
Bee numbers have plummeted in the U.S. but a new study in Detroit suggests the city's large amount vacant land may have led to higher numbers. Detroit has lost more than half of its population since the 1950s, leaving thousands of lots abandoned in of the city's urban core as once-plentiful jobs in the auto industry were lost to automation and the economy plummeted. But a study released by the University of Michigan in May appears to show those economic struggles may have also created positive ecological influences for a portion of Detroit, where researchers found higher bumblebee populations than less-urbanized areas of the state.
Global Good News service views this news as a sign of rising positivity in the field of science, documenting the growth of life-supporting, evolutionary trends.
Researchers say the study, published May 17 in the journal Royal Society Open Science, gives strong evidence that thousands of vacated residential properties in the Motor City may have led to the increases in bumblebee populations, potentially due to the lack of humans, many of whom use pesticides and herbicides and mow their lawns.
. . . 'But then once we sampled in Detroit, we found a particularly surprising uptick in the amount of bumblebee abundance and in bumblebee diversity,' Glaum said.
