@rms I doubt the mercury is the primary cause of the high suicide rates (since native communities in Canada tend to have much, much higher suicide rates than the general population due to numerous other factors), but there's no doubt that it's causing countless issues, and that those issues would likely compound with all of the existing factors that normally lead to increased suicide rates to further increase it. And beyond its impact to the people living there, the environmental impact of it is unfathomable. To quote the article, "A single gram of mercury is sufficient to make all fish in a 20-hectare radius unsafe for consumption" - so how much destruction will 20,000lbs cause? That's a level of environmental damage that's likely impossible to actually fix, especially after such a long period of being ignored. The animals and plants living there are likely forever posioned for countless generations to come. Even if the mercury could somehow be removed, the scars of the damage it has already caused to the wildlife and ecosystem will remain for longer than we can imagine.
