Roughly two thirds of the planet’s available surface freshwater is contained in just 20 lakes. Scattered around the globe, and diverse in almost every measurable respect, these immense “dimples” in earth’s surface have shaped human society and history. Their value continues to grow as freshwater scarcity increases.
A special talk highlighting these lakes and their importance will be held at 3:30 p.m. April 29 at the DECC in Duluth. The talk will explore earth’s largest lakes, some of which are in our backyard, from the standpoints of hydrology, biogeochemistry, biodiversity, and geopolitics, using these approaches ultimately to ask what role these places play in our lives. Dr. Robert Sterner will be the speaker.
This ties in with concerns and efforts about restoration of the forest adjacent to Lake Superior and how it protects the big lake’s water quality.
The program is sponsored by the North Shore Forest Collaborative.
