Humans produce a lot of garbage. Oftentimes this trash is thrown on othe gorund by ignorant poeple., Papers, cans, wrappers, and many other things can often be seen on the streets. If there were no one to clean these things up, can you imagine what type of environment we would live in? Our world would be mor polluted, dirty, and unbearable. Street cleaners provide a valuable service to our society andthe world. In my eyes, they are truly great heroes. In this day and age, the work they do is more important than ever before.
