Where have all the Froggies Gone?
Minnesota and Eager Bio Student
  So Nermit traveled to Minnesota where the News Frog said this whole thing began.  In 1995 students from the New Country School first discovered many cases of deformed frogs. There he talked to a student who had found deformed frogs. He also wondered why the frogs were deformed and disappearing. The student said “Pollution to the environment like agricultural chemicals may be affecting frogs. The chemicals used to make crops grow better can be dangerous to tadpoles and adult frogs.”
