We humans are a wanton and wasteful lot. Take this plastic Coke bottle in my hand. It burns for a lot longer than you'd think, and hot, too. Even though someone went to a lot of trouble to make this bottle, it goes to the landfill when I'm through with the pause that refreshes. All that energy wasted.
Water is another example.
Drive across town in summer and watch how many sprinkler systems water the sidewalks, driveways, streets and gutters. Look closely on a windy day and observe how much of our precious groundwater is flung into the wind by sprinklers. We even water our lawns during thunderstorms, though all it takes is the push of a button to cancel the program on a rainy day. I'm not griping about wasting water. I do it, too.
