Six Republican members of the U.S. Congress from Wisconsin and Minnesota have sent a letter to Canada's ambassador in Washington urging Canada to address the issue of wildfire smoke drifting across the border and affecting the Upper Midwest. The lawmakers criticized Canada's forest management practices, stating that the smoke from Canadian wildfires has made it difficult for residents in their states to enjoy outdoor activities during the summer. The smoke has caused unhealthy air quality conditions across parts of the northern United States, including Minnesota, Wisconsin, and North Dakota. Manitoba Premier Wab Kinew has responded to the complaints from U.S. lawmakers. The situation highlights ongoing concerns about cross-border environmental impacts from Canadian wildfires.
