You're rigth oh8eleven, when the MSM doesn't mention who the "researchers" are - good chance it's an enviro-whacko who also backs Gore's global warming bulls-it.
If they have "proof" they should name it - and the researhers and the study - and where the information was published.
None of us believe so called "scientists" on faith any more. Especially un-named ones quoted by the MSM...
When me and my bro were kids, there were a lot of wingless flies in our neighborhood... :-)
