About 60% of all food consumed in the U.S. has a relationship with the bee through pollination. The services these oft feared insects provide is beyond measure. In fiscal terms, America would lose an estimated $20 billion in crops without the pollination bees provide. Lately however, their numbers are declining fast due to the varroa mite, an invasive species first found in the U.S. in 1987. Phenomenons such as this underscore one of the potentially negative economic consequences of globalization. While much of the world has enjoyed the economic pleasures of the expanding global market, the increased proliferation of world trade allows for a greater exchange of invasive species such as the varroa mite.
