- I believe that the main motivation of introducing kudzu was as a
- conservation crop to prevent the soil erosion of your item 1. The
- conservation folks were right about it being a good cover crop!

- Clearly introduction of exotic plants is sonething that must be done with
- great care. But it can also be useful. We would have a rather bland
- diet if we used only plants native to the US--corn is from Mexico, wheat,
- rice and soybeans from Asia, Potatoes from South America. Crustless
- pumpkin pie would be a big item, but I think I might still be hungry.
