Frog deformities not caused by pollution or global warming after all

For years - heck, I was taught this in school - we have been led to believe that frogs are ultra-sensitive to environmental change, and that the prevalence of frogs around the world being born with deformities such as missing limbs is a sign of pending environmental catastrophe.

This claim has now been found to be totally bogus. From the BBC:

The deformed frogs are actually victims of the predatory habits of dragonfly nymphs, which eat the legs of tadpoles.

So, is there an environmental catastrophe looming around the corner? If you think so, you need evidence, and the list of evidence that conforms to this assertion is growing smaller by the day.
