Nova Scotia; A Mercury Hotspot

As I was reading over the local newspaper (Chronical Herald), i saw an article that said N.S was one of the top 5 hotspots for Mercury (the other four places were in New York and New England). Mercury is ending up in the lakes around the area (Including Kejimkujik national Park), and the local wildlife is consuming it. This does not only effect those animals, but it effects the rest of the foodchain. Abnormal amounts of mercury (as much as 8x greater then normal) are ending up in the fish and birds (loons) in the area. If the National Parks are being invaded with toxic chemicals, like Mercury, and harming the wildlife in the area, whats going to be left in these parks in the future? Not only do scientists need to start looking at these issues, but so does the rest of the world, including the big Corporate Businesses that are mainly responsible for toxicating the wildlife. Some of the toxins are coming from the rain, but chemicals such as Mercury can stay around in the atmosphere for several months before it exits out, and most of it is ending up in the worlds waters. Not only are these toxins harming the wildlife, but they are contaminating animals that humans will consume, which harms us as well. But do the Big Businesses think about the long term effects that chemical dumping and smoke stacks will have on our planet?
