Environmental issues have reached critical importance in our era defined by major climatic shifts. The exhibition ''Ecologies: A Song for our Planet'' features installations, videos, sculptures, paintings, drawings and photographs that speak to mankind’s relationship with nature. It is presented as a rotation of some 90 works stemming mainly from the MMFA’s collection, including several new acquisitions by Jocelyne Alloucherie, Shuvinai Ashoona, Olafur Eliasson, Charles Gagnon, Lorraine Gilbert, Jessica Houston, Isabelle Hayeur, Alec Lawson Tuckatuck, Lisette Lemieux, Monique Mongeau, Marie-Jeanne Musiol, Peter Qumaluk Itukalla, Claude Simard and Barbara Steinman. Alongside Ecologies, the MMFA will present Paul Walde’s video installation ''Requiem for a Glacier,'' a musical composition performed by 50 musicians on Farnham Glacier, British Columbia.
