It is the policy of the general assembly that young persons should assist in the preservation of state parks and recreation areas. The commissioner of environment and conservation is encouraged to employ persons under nineteen (19) years of age to work in state parks and recreation areas. These persons should be employed in nonhazardous duties that enhance the viability and purpose of Tennessee's pristine parks. The commissioner shall provide an annual report to the energy, agriculture and natural resources committee of the senate and to the agriculture and natural resources committee of the house of representatives on the number of persons under nineteen (19) years of age who are employed to work in state parks and recreation areas, and in which state parks and recreation areas such persons are employed.
