►June 28, 2018: Nature Speaks: Consilience, Concinnity, and the Way

Speaking at Prospect Heights Public Library at 7 PM on June 28, 2018. This program is co-sponsored with the Prospect Heights Natural Resources Commission.


Consilience means “jumping together” and is typified when all the elements of an ecosystem are working in harmony. The health of an ecosystem is directly related to consilience. If one acknowledges that plants and animals grow in habitats to which they are adapted, then one must accept the corollary: Change the habitat and the inhabitants change. All elements in an ecosystem must be in consilience if the system is to remain stable enough to endure changes at the rates at which mountains rise and fall.

►June 19, 2018: Chicago Line Cruise Eco Boat Tour

"Chicagoland Ecosphere Balance and Design," an eco boat tour on June 19th from 6 to 7:30 PM with Dr. Gerould Wilhelm, Conservation Research Institute; Terry Guen, FASLA, TGDA Urban Ecological Design; Roy Diblik, The Lurie Garden


The Chicago River is a complex intersection of ecology, architecture, and urban design. While less attention has been paid to Chicago’s ecological history, it remains the basis from which our city developed and holds a key to Chicago’s sustainable future. This summer 2018, Chicago Line Cruises is partnering with The School of the Art Institute of Chicago and city organizations to present a series of 5 eco boat tours and water workshops. Beginning at the Ogden Slip, experts in ecology, planning, and design will engage riders en route to discuss topics such as: the Chicago Region’s ecological significance on a global scale, achieving ecological balance in an urbanized world, delivering ecological conservation, and fresh water as social justice through balanced urban and economic development. This tour is to further understand the critical role of humans in creating and caring for urban nature, and to provide cues for achieving higher environmental qualities in where we live.
