Bees are dying at an alarming rate. Amsterdam may have the answer.

While scientists have been sounding alarm bells over the decline of bees globally, Amsterdam may have worked out how to save them.

A study by the University of Vermont found that the wild bee population in the United States declined by 23 percent from 2008 and 2013. The most worrisome shortfall occurred in key agricultural regions, including California, the Pacific Northwest and the Mississippi River valley, that depend on pollinators.
