The Prince of Wales listed a number of challenges facing the world from the widening gap between rich and poor to inequality for women and young girls to climate change after he was honoured today as part a four-day trip to Canada.
Known for being outspoken on social and environmental issues, Charles spoke about the "nexus of water, energy and food security" as the world's population grows and "finding common purpose in meeting our common needs."
"It is all our grandchildren who will have to live with the very serious consequences of us believing today that we can simply carry on with business as usual as if nothing has changed."
Grandson Prince George, the son of Prince William and his wife Kate, was born last July.
Charles and Camilla wrap up their visit tomorrow in Manitoba.
