Guest: University of Minnesota Assistant Professor of Entomology Vera Krischik

Scientists are expressing concern about the declining numbers of pollinating insects such as bees and butterflies. Urbanization, the loss of prairie land and the use of pesticides have all contributed to the problem. But there are things that land owners and homeowners can do to make their properties more pollinator-friendly.  University of Minnesota Associate Professor of Entomology Vera Krischik discusses the role of these beneficial insects.
