On-line Flashcards
What happens when bison do not recognize Yellowstone's legal boundaries, but Montana's officials of livestock management do? Once bison leave the park, they are under the jurisdiction of state officials, and state policy dictates that bison must not roam freely outside the park. To further understand this controversial management policy, read Should Bison Leaving Yellowstone National Park Be Shot?
      For further stories that emphasize the sometimes controversial interactions between people and wildlife, and the interrelated nature of environmental problems, read: Judge Rules on Excessive Fishing in Alaska, Canadian Government Takes Steps to Conserve Salmon, Environmental Concerns in the "Battle for Seattle," at World Trade Organization Talks, and China Slated to Join the WTO.
      Regional environmental concerns, from the poaching of mushrooms in Pacific Northwest forests to water levels in the Great Lakes, can be explored in the following case studies and environmental stories: Matsutake Mushroom Mania, The Prairie Wetlands of Southwest Minnesota, PCB Contaminants in the Fox River, Protecting Groundwater Resources, BP Petroleum/Amoco Admits to Dumping Toxic Waste on Alaska's North Slope, Historic Decision to Allow Drilling in Remote Alaska Oil Reserve, Major Fires Expected in Popular Wilderness Area, and Low Water Levels in the Great Lakes.
Bioaccumulation is mentioned as a major concern in the Great Lakes and in the industrial Northeast. This concept will be further discussed in chapter 15, but now you can see an animation that brings the concept to life at Bioaccumulation.
