There are food safety and hygiene problems.
Eating the leftovers in the trash can face to face may have food safety and hygiene problems. The food in the trash can may have been touched by others or contaminated. Eating these leftovers may lead to food poisoning or other health problems.
May be misleading.
This kind of behavior may be misleading. Children may mistakenly think that they can eat other people's leftovers at any time as long as they don't waste food. This will lead to bad eating habits and health risks.
Other educational methods
Therefore, a better way is to educate children about the importance of saving food through other channels, such as involving children in food purchase, making a reasonable diet plan, understanding the source and production process of food, and donating surplus food to people or animals in need. This can not only ensure the health and hygiene of children, but also cultivate their food awareness and sense of responsibility.
