Read this excerpt from a blog.
As a professor of environmental studies at the University of Nebraska, I was alarmed to discover that local farmers are increasing their use of pesticides on wheat fields. While these chemicals help to get rid of the insects that damage the crops, they also cause great harm to butterfly and honey bee populations. These insects are a necessary part of our ecosystem because they spread pollen that allows our plants, flowers, and crops to grow.
