As I briefly said earlier, we have to educate young people. They are like sponges. They will accept the model proposed to them without questioning it. We cannot go to high schools and tell the students that what they have been doing for 10 years is wrong.
They should be accustomed to that approach, just like they accustomed us to recycling. You can no longer put an empty tin can into the garbage without a youngster in the kitchen saying:
“No, no, no Dad, don't do that, put it in the recycling bin.”
It's a matter of habit.
