Joe’s fascination and conservation concern for raptors broadened into a concern for the grassland ecosystem as a wholeand ultimately the health of the planet and the people within it. As a board member of the Saskatchewan Environmental Society, he helped expand some of the great action programs the SES delivers.                                                                     

Through his participation in an SES entrepreneurial subcommittee, he helped establish the SES Solar Co-operative Ltd. The SES Solar Co-operative Ltd. is a community-based initiative.

He hopes that federal and provincial governments will follow our lead toward efficient adaptation for sustainability in Saskatchewan.
