Descrição do livro

The National Great Lakes Inventory examines the bioaccumulation of lead, and other contaminants in Bald Eagles, a sentinel species to assess the health of their semi-aquatic ecosystem. What effect do lead-based contaminants, and chemical run-off have on the native wildlife, and the surrounding ecosystem? Discover this, and more as we uncover the truth through years of monitoring, and investigation into the devastation of lead contaminant accumulation in the tissues of its unsuspecting victims, through our charismatic, and iconic national symbol of hope, freedom, independence, courage, and strength the bald eagle. The efforts made by leading scientists to monitor, and protect this beautiful, and majestic species from these threats has led to a full recovery of the species after the population declined dramatically, and they were listed on the Endangered Species List in 2007 under the Endangered Species Act (1973). The population numbers have continued to increase over the years. The Bald eagle's story is a great success story because the extensive recovery efforts have led to the federal delisting of this species on the Endangered Species List, with continued monitoring, and protection through the Bald and Golden Eagle Protection Act (1940), and the Migratory Bird Threaty Act (1918).
