The impact on my son was huge. The facts, information and overall knowledge of the environment and sustainability was exciting as parents. This style of learning was perfect for my son and he is already talking about changes we can make at home and at his school. He said the trip changed his life and had a huge impact. He is very aware of the food he puts in his mouth and the level of activity (or lack there of). He lost 14 pounds on the trip from eating fresh, no processed food and exercising every day. He found he loved water more than soda and wants to plant a garden with fresh vegetables. I have nothing but positive things to say and was really happy with the program and impact on my teen.
