The growing pace of forestry, oil and gas, and mining developments in the boreal region of Saskatchewan could alter the ecological balance in this region with numerous potential environmental impacts to the surrounding land and water. In particular, as the industrial footprint of the Athabasca Oil Sands Region (AOSR) in Alberta continues to expand, emissions of pollutants will continue to increase, with potentially detrimental impacts (e.g. acidification, nutrient loading) on the lakes, rivers and wetlands downwind of this development. An emerging issue that has not been addressed is whether recent increases in lake production in regions adjacent to and downwind of the AOSR are linked to emissions of nitrogen or changing climatic

在萨斯喀彻温省北部地区，森林、石油、天然气和矿业开发的步伐日益加快，可能会改变该地区的生态平衡，对周围的土地和水产生许多潜在的环境影响。特别是，随着阿尔伯塔省阿萨巴斯卡油砂地区（AOSR）的工业足迹不断扩大，污染物的排放将继续增加，对该开发项目顺风方向的湖泊、河流和湿地产生潜在的有害影响（例如酸化、养分负荷）。一个尚未解决的新问题是，最近在AOSR附近和下风地区湖泊产量的增加是否与氮排放或气候变化有关
