Artwork description: Every disposable lunch box scattered on the ground has its own number, every non-degradable disposable lunch box is the prime culprit of the destruction of the natural environment. The various disposable lunch boxes are made by the method of molding and restoring, and are stacked on top of each other, just like the real disposable lunch boxes are scattered on the ground at will. The work uses transparent, recyclable glass material to show these eco-hazardous foamed tableware, with contradictions and conflicts. The ban and lifting of the ban on disposable lunch boxes are controversial. This is not only a one-off lunch box plan, but also an action to protect the ecology.
