"There are more and more scavengers in the neighborhood", I think this is not the same as real scavengers, they should be called garbage collectors. They are also contributing to the environmental protection of the neighborhood, and with their presence the inside of the neighborhood will become cleaner and more hygienic.
My mom has the habit of picking up paper boxes, drink bottles and other garbage discards, and every night when she goes to square dance and comes back, she either takes a few drink bottles or a few paper boxes in her hand. The storage room in my house has become a place for her to store her garbage, and of course she disposes of it on a regular basis. In her words, "I feel bad when I look at the bottles and cartons that are thrown away, and I can sell them for money when I save more."
At first, the lady who danced with my mom would give my mom some garbage that could be sold for money, and now she's starting to pick it up. This is the effect of influence, one person picks up everyone follows. I've witnessed that mom's eyes light up at the sight of a cardboard box and run all the way over to it, and she was more passionate about it than she was about the money.
My object a few days ago also joked with me that: "I am now letting our mother influence, in the company to see the finished drinks bottle, have to pick up the urge to take away." I laughed out loud. Picking up garbage is really contagious, even young people like us have the urge to pick it up.
There are 24 buildings in our neighborhood, and sometimes when I go out for a walk at night, I often see some older people with a cardboard box or a drink bottle. Some of the elderly people during the day when there is nothing to do will also be in the neighborhood, see the garbage will be picked up and thrown to the garbage can, if you can sell the money to take home. This behavior should be strongly advocated, they are loyal guardians of the environment.
