Children are important, and it is a misfortune that in virtually all industrial nations the birth rate is declining. There is lots of thought and public discussion in Germany these days about the right upbringing and education for children. Often the issue is centered on values. What values are important and how should parents and society impart these values to the adolescent generation?One value that in my opinion belongs, among others, to values education, but which has not yet been taken into broad consideration, is ecological, sustainable behavior. By this I mean, for instance, respect for natural resources – frugal use of water, conscientious energy consumption (heat, electricity). Children don’t learn frugality incidentally, but more exactly when they are deliberately introduced to it, best of all by persons who lead the way by example.
