Ranking of Top 500 influencers and players active on Twitter in connection with the #GreatLakes community. Weekly update day: Tuesday.

The #GreatLakes500 SustMeme Twitter influencer list has been built to promote a positive dialogue and increase engagement across the largest freshwater system in the world.

When conceptualised as a region including the US and Canada, the #GreatLakes represent the third largest economy in the world. The Great Lakes Basin is home to more than 30 million people — roughly 10% of the population of the US and 30% of that of Canada. It also contributes nearly 25% of Canadian agricultural production and 7% American farm output.

The #GreatLakes are, however, at risk. Climate change, emerging contaminants, pollution, biodiversity loss, harmful algal blooms, and other stressors threaten both the ecosystem and regional economy — impacting everything and everyone, from livelihoods to wildlife.

Therefore, it is hoped this #GreatLakes500 ranking will lead to knowledge exchanges and improvements in stewardship of this amazing freshwater resource.
