Robert Krulwich - wrote a post called "Migration Blues: When Birds Don't Fly South". As I read his post my mind had a hard time wrapping my head around what is happening. If the animals stop migrating, not only will it affect their own species but what does it mean for human kind? What is causing this phenomena?
Krulwich creates a powerful scene when he writes - "Simply stated," says Princeton professor David Wilcove, "the phenomenon of migration is disappearing around the world. The great salmon runs of the Pacific Northwest have been reduced to a trickle ... Monarch butterflies are threatened by illegal logging of the Mexican forests where they winter. "
More and more studies show fewer creatures are migrating and those who do more often don't make it. There is no easy way to address this problem."
Krulwich writes: "Krulwich Wonders, NPR Sciency Blog. He tackles science and explains what is happening. A great science blog to use with students. The migration post shows the interconnectedness of many issues. Great discussion piece.
