It is pointed out that plastic microbeads may negatively affect marine ecosystems. One of the materials to solve this issue is biodegradable plastic. We aim to popularize this protean plastic, which contributes to global environmental conservation, in an innovative way. Imagine that, for example, when domestic garbage put in the biodegradable plastic bag is buried in the ground, seasonal flower will spring from the ground. A seal-type small bag containing seeds is attached to a biodegradable plastic bag. Buried in the ground, the plastic bag is degraded to water and carbon dioxide, and this water wakes the seeds up, giving birth to new life.Microorganisms in soil degrade organic materials to create nutrients, which are reabsorbed and circulated by plants. Strongly hoping for the recovery and spreading the grass in the area, we can create peaceful atmosphere in cities and the activity will finally lead to global environment conservation. Let's draw a green picture on the earth.
