“A: Every plant can be evaluated through a cost-benefit analysis. The ecological costs of autumn olive are enormous. They are one of the most invasive plants we have, and they decimate local plant and animal diversity and thus threaten ecosystem stability and function wherever they spread. Autumn olive berries might provide cancer-fighting benefits, but so do berries of many native plants (elderberry, for example). We can take advantage of other sources of lycopene. In my view, this is a clear case where the costs of planting a nonnative species far outweigh the replaceable benefits.”
