A quote from Albert Mohler:
If you adhere to an old earth position you have a very difficult time explaining how the effects of the Fall--death, disease and suffering--showed up long before Adam and Eve.
[from the current Creation magazine]
The article also cites a couple of papers on the topic:
Plants and death, and
Romans 8
I've posted with reference to Mohler previously, on the Framework Hypothesis, and the age of the earth.
