Ecological Impacts of MiningCurrent LectureHousekeeping and News Coyotes in Chicago Proper City Coyotes have larger ranges than Suburb coyotes. This is because it’s harder to find food. Thisshows that there are species that are highly adaptable to our environment and can live under the radar. Moodle Submission Status A lot of people didn’t hit the final submit button. She has a record of every assignment that was in on time. System lockedEcological Impacts of Mining Metallic Mining in Wisconsin Mining has a pretty high impact. You remove all of the trees and vegetation on the surface to getat what’s underneath. It’s an intense disturbance. Frac Sand Mining Logistics Wisconsin has a lot of sandy soil in the western portion of the state that is really good for fracking. The sand has fine, stable grains that work very well for fracking. Not everyone wants to frac in Wisconsin, but they want to mine the sand Greatest concern associated with frac sand mining?These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. Air quality: It puts a lot of small particles in the air that are potential carcinogens. It’s on par with asbestos, and can lead to lung cancer. Those downwind of sand mines are concerned. How many frac sand mines are currently operating in the state of WI? Over 100 mines are operating in the state Mining for sand isn’t necessarily new. The problem is there’s been a HUGE spike in sand mining. This sharp jump in mining operations means that there’s greater exposure to people and greater potential for ecological damage Why is the demand so high? The fracking industry uses the sand. What are the local economic benefits? It creates jobs What are the ecological implications? There’s noise pollution. Removal of top layer of land such as prairies. Frac Sand Mining Video on Controversy There are positive impacts with job creation, but it can negatively impact tourism. Frac sand mining has boomed, but there hasn’t been an opportunity to do a lot of research. It’s hard to say the impacts. Without numbers to prove how harmful it is, it’s hard to stop. Fight for Wisconsin’s Soul “But now, after the recent passage of a bill that would allow for the construction of what could be the world’s largest open-pit iron ore mine, Wisconsin’s admirable history of environmental stewardship is under attack” The political atmosphere has changed and is moving away from the Wisconsin’s legacy of environmental concern to economical concern Proposed mining area in Northern Wisconsin It would be miles long. It’s not an isolated area that they’re digging up. There are forested ecosystems up there. A negative consequence to destroying this more pristine forest could have an impact on water sources and society. Ecological Impacts Sulfides – lower pH in waterways Drainage to Lake Superior Asbestos form minerals becoming airborne “In the Chippewa tradition, a decision is made based on how it will affect people seven generations forward. By contrast, the company’s optimistic estimate for the lifespan of the first phase of the mine is 35 years” – Fight for Wisconsin’s Soul Importance of informed voters These are politicians that want to pave the way for this mine Consideration of long term consequences Outside of Butte, Montana, there is a superfund site because of a mining operation. There is a balance between ecological implications and ecological
