>>we've looked at pesticides and bees from the early 1970s through the 1980s and 1990s, with our last major, broad spectrum work done on the east coast in the late 90s, early 2000s. That's data spanning decades. Great! What has been the trend? Have the pesticide levels and types increases or decrease or remained the same?
