In spite of the success of the implementation of Montreal Protocol, the ozone level is not expected to return to 1980's levels until this mid-century because of the remaining chloroflurocarbon (CFCS) in the atmosphere. Therefore, ground-level ultraviolet-B will still stay in a high level in the next several decades and be a significant factor on the growth and development of all crops including sweetpotatoes.
