The main purpose of the development of disposable lunch boxes is to facilitate people's lives, and then garbage will be generated. Although paper can be degraded, it also takes time. Now more methods are recycling.
What is really good for the environment is planting more trees, which does not conflict with the use of disposable lunch boxes. The creation of environmental greening and the provision of life convenience can be carried out at the same time.
