19 A lack of sea ice or poor ice conditions causes stress for marine mammals and affects their abilities to reproduce. Expected reductions in sea ice will shrink marine habitats and may push some species to extinction. Loss of sea ice can create more severe storms, cause accidents on thin ice, and makes people have to travel farther to hunt. Next Polar bear. Courtesy of Marc Webber, U.S. Fish and Wildlife Service.

25 Walrus do live in the Arctic. But they arent alone! Try Again Walrus herd in the Bering Sea. Photo by Maggie Prevenas (PolarTREC 2007). Courtesy of ARCUS. I give up, whats the answer?

26 Yes, many animals live in the Arctic, including, polar bears, arctic foxes, walrus, seals, caribou, whales, a variety of birds, and even people! But, penguins do not live in the Arctic. They ONLY live in the Antarctic! Walrus herd in the Bering Sea. Photo by Maggie Prevenas (PolarTREC 2007). Courtesy of ARCUS. An Adelie Penguin in Cape Bird, Ross Island, Antarctica.

34 A. The sea ice system is very complicated. The sea ice system is very complicated. B. That the arctic sea ice is actually growing. That the arctic sea ice is actually growing. C. That polar bears can survive without sea ice. That polar bears can survive without sea ice. D. That the world will be a better place when the arctic sea ice has melted completely. That the world will be a better place when the arctic sea ice has melted completely. Choose the BEST answer. Skip to next questionBack to question 8

35 Try Again I give up, whats the answer?

36 The sea ice system is very complicated, and many factors affect the way it is changing. Scientists know that greenhouse gasses have increased the mean global temperaturesand this increases sea ice melt. They also know that the sea ice is melting faster than anyone predicted. Scientists will continue to study the system to learn how changes will impact our world. NextBack to question 9

Change your light bulbs to compact fluorescents Change your light bulbs to compact fluorescents D. Unplug electronics when they are not being used Unplug electronics when they are not being used E. Support local agriculture Support local agriculture F. All of the above All of the above Skip to end Back to question 9

39 Try again. I give up, whats the answer?

40 A major contributor to melting sea ice is global warming. To help slow global warming, and slow sea ice melt, there are several things you can do to reduce your carbon footprint, including: - Carpooling, walking, or biking more - Recycling - Using compact fluorescent light bulbs - Unplugging electronics when not in use - Supporting local farmers.
