This reader asks a very interesting question that I have witnessed frequently but never thought of:
“Basically.. almost every building in the city cleans the sidewalks by spraying them with a hose. Some guy stands there and uses a regular garden hose to wash away everything into the gutter every day. What a waste is that? What ever happened to a broom? Are they so lazy? Is sweeping really so inferior that anyone would notice how much dirtier the sidewalk is? It seems stupid to me.
Greenpeace and all these people are all environmental and all that and right where they stand, countless gallons of water get wasted daily for no visible benefit but everyone kinda just walks by.”
