On November 30th, leaders from around the world will sit down and make an international agreement on how each country will work together to cut global warming pollution.

The toxic mining spill in the Animas River made international news, but it also helped highlight a problem that is long overdue for a solution. Hard rock metal mining is the most destructive industry in the world. The mining industry should not be allowed to use our public lands to build new mines in and around our cherished waterways until it cleans up from past mining operations.

Last year at this time, the toxic algae bloom in Lake Erie caused nearly half a million people in and around Toledo, Ohio, to be without safe drinking water. Clean water from our taps is something that many of us take for granted, but if we don’t protect our water sources — like the residents of Toledo discovered — we won’t be able to take it for granted anymore.
