At this moment, the environmental defender litter box emerged, which contained the garbage in his arms and gave the environment a comfortable and clean atmosphere. The garbage in the lake is no longer there, because the garbage bins at the lake remind the tourists that they should place the rubbish in the bins. Then the clear lake is pleasing to the eye. The fresh air makes people enjoy the quiet and fresh environment on the lake. This kind of goodness, if delivered to every place, then the rubbish bin is the leader in ecological protection. It also contributes intrinsically to the development of our society. The rubbish of the streets disappears, and every passing person Everyone smiled and no longer littered as they once did. They understood the role of bins and no longer made the rubbish bin a fitting. Gradually, the environment became better and better, and the country’s economy developed. How can a good country not be really tall and upscale? Let the conservation of ecological waste containers continue to be the city's maintainers, so that the garbage will no longer be a good ecological barrier.
