7. Use a broom.
I have blogged about this before, but now I think I really underestimated my calculations. Every day I see more and more people using the hose to clean their sidewalk. Maybe I am paying more attention than I used to. But the point is, we can't keep dumping water, one of our most precious and scarce resources, into the side walk. It’s socially irresponsible. I know it’s easier. I know some of you are just probably following orders. But if we focus on the solution, we can find better ways to do this. What we need is a clean sidewalk, right? What about using a broom and a bucket of water? You will be amazed how that does a better job even than just the hose. Try it and help the world save water. Click this link to my previous post if you are curious about how much water we dump watering sidewalks – just in Manhattan. Hint: a lot.
