The Great Lakes Ecoregion Network (GLEN) is a new initiative to engage members of the basin-wide Great Lakes environmental community on issues related to the binational Great Lakes Water Quality Agreement (GLWQA). As the 50th anniversary of the signing of the GLWQA is celebrated later this week, we call on the US and Canadian federal governments to renew and strengthen their commitment to water quality and ecosystem health in the Great Lakes-St. Lawrence River Basin.
