Junior Lifeguard program for children

Junior Lifeguard program is getting more popular in u.s by educating children to recognize potential hazardous conditions. One of the lessons called speed drop which require students to let go at the back of the moving boat and swim back to shore. Students learn different skills thru rescue simulation, swimming under currents..
Parents think this program is very helpful in teaching children of how to handle in water. Though, I felt that programs for children which involved certain degree of risks are just unnecessary..
