Saplant / Shovel

Saplant is made of bio-degradable plastic that is helpful for the growth of plants so if it is planted in soil where a tree is planted, it gets slowly dissolved in the soil, which becomes nutriment to the tree. It is not throwaway.
When it is time to replace Saplant with a new one, plant it in the ground. It is not an industrial waste, but nutriment to human beings and environment.

It arouses our attention to environmental pollution and it encourages us to plant trees
so it leads us to directly practice the protection of environment.
