【2015高考复习】阅读理解 Two things I really believe in—saving money and saving the planet,and it's even better when I can do something that accomplishes both at the same time.
Rainwater harvesting is just such a thing.In the near future,rainwater harvesting will be as common as twelveyearold girls carrying cell phones.
Many countries already rely heavily on rainwater.Bermuda,for example,every building on the small island collects the rainwater from its roof and stores it for later use.However,America_is_just_slightly_behind_the_curve.
There are many ways you can begin harvesting rainwater and most of them are easy and inexpensive.Use rain barrels to collect the water that would run off of your roof.You'd be surprised how fast a fiftygallon barrel will fill with free,usable water.New building construction offers some good ways to gather rainwater,and the cost of installation is usually offset by reduced usage very quickly.Roof drains can be piped into underground tanks,where a pump can draw it up as needed.
The rainwater can even be treated to make it drinkable...but wait—there's more!If that rainwater were not collected,but allowed to run over your lawn,into the street and eventually to a stormwater treatment facility,it would pick up all sorts of pollutants on its journey—fertilizers and pesticides from the grass,motor oil,antifreeze and such from the roads,and who knows what else.
