It's all so simple

Polar bear remains found in shark's stomach - Telegraph

The United States this year listed polar bears as threatened under the US Endangered Species Act because their sea ice habitat is shrinking, apparently due to global warming. A thaw may mean that bears spend more time in the water.

Ok, so the energy you used for your sick baby's hot water bottle may have caused more coal to be burned, which caused carbon dioxide to be released, which may have caused global temperatures to rise, which may have caused Greenland ice to melt, which may have caused a polar bear to swim more, which may have given a shark more time to catch it, which may have resulted in a polar bear bone being found in a shark's stomach.
