Trash Filter

When I took a walk around my living environment, I found a lot of trash on the ground. It was quite impressive because we have garbage sorting rules in Shanghai. Or we can say the sorting rules are the origin of throwing litter. In Shanghai, we can only throw our trash from 7 to 9 a.m and 6 to 8 p.m. Besides, in my housing estate, there are just three areas for garbage bins. These three areas are near the three big gates of the housing estate. It is not that convenient for the residents. So, the trash is thrown randomly. 
When I hunkered down and saw the green grass, I found a plastic bag on the grass. And I can't help associating to children's perspective. If children, little kids, even the next generation. When they recognize things, they will confuse some white "grass" or other color's grass. People want to ignore the trash like the filters in people's eyes. The garbage is not disappeared. They have been covered. We have just hidden the fact that we all knew.
