Personally, I think this kind of education is not desirable, which may stimulate children to cherish food at that time, but this way of eating garbage can leftovers is not desirable.

First of all, the environment in the garbage can is very easy to breed bacteria, and eating the leftovers in the garbage can easily bring harm to your body. Personally, it is not advisable to educate children in such a way that harms them, which is extremely extreme.

There are many ways for children to learn to cherish food. There is no need to use this extreme method. There are many ways for children to learn to cherish food, such as letting them watch some educational movies and explaining why they are not allowed to waste food in movie clips.

For another example, watch some interviews or international programs to let children know that people in many places may not be able to eat now, let children know that wasting food is a bad behavior, and let children know from their own consciousness that wasting food is really not desirable.

You can even lead children to volunteer, find some remote areas and places with difficult family environment, so that children can realize the importance of food to themselves.

In short, I personally think that there are many ways to educate children not to waste food, and parents' behavior is extreme. I personally think it is inappropriate for children to eat leftovers in the trash can in front of themselves.

Because we should not only teach children to cherish food, but also teach them how to develop good eating habits healthily.
