Wildlife Quiz: What river valley has the most important habitat for grizzlies, wolves, wolverines and lynx in the Rocky Mountains?

Hint: The river forms the western boundary of Glacier National Park, and straddles the Canadian/US border between British Columbia and Montana.

Answer: The Flathead River.

The Flathead was recently named British Columbia's most endangered river, and the fifth most endangered river in the United States.

Why? British Columbia's land use plan ensures that mining for coal and minerals can trump all other land uses in the Flathead valley.

Imagine being born today in the South Pacific island nation of Tuvalu, half way between Hawaii and New Zealand.

You join a community of 12,000 people with a unique culture, language and traditions for sustainable fishing and farming developed over thousands of years. Your country consists of nine small islands covering just 26 square kilometers and averaging only three meters above sea level. Because soils are poor and there is no surface fresh water, your family depends on rain and a thin layer of ground water to grow taro, coconut, bananas and breadfruit.

By the time you are ready to have children of your own, climate change may have made life in your island home nearly impossible.
