For centuries, the Great Lakes have served as an important food source and trade route for people living along their shore. Today, that rich history is a draw for tourists as well as divers interested in the lakes' thousands of shipwrecks.
Milwaukee Journal Sentinel reporter Dan Egan has covered Great Lakes issues for 15 years. This month, he released his first book, The Death and Life of the Great Lakes, an in-depth biography of the lakes – from the opening of the St. Lawrence Seaway to the current issues with harmful algae blooms and invasive species.
Hear why reporter Dan Egan wrote The Death and Life of the Great Lakes.
For more than eight decades, an Australian lungfish named Granddad resided at Chicago's Shedd Aquarium. The beloved fish made the journey from Australia by steamboat and train to dazzle attendees of the legendary 1933 World's Fair.
Since then, the aquarium estimates some 104 million guests have seen the famous lungfish.
