Well in the past year I have read many entires on here where folk seem to think so.
An interesting article here from the BBC News that agrees with those people, but there may be hope.

I didn't guarantee hope just hinted at the possibility ;-)
Sadly the solutions people like Monsanto want to sell us don't solve the problems and create others...
