Very true. After reading that article and doing some initial research on the early internet I found a lot of people were worried that this indicator species(?) was signalling that waterways were in trouble, farm runoff was too heavily polluted by herbicides and nitrates and amphibians were disappearing, not just in the US but globally. It was an interesting article about a serious issue and for a short time it was in the news but then it just went away. Except it didn't.
