Water

你知道吗?在地球上,少过0.5%的水是适合人类、动物和植物使用的。
真正的数字我忘记了,95%以上的是海水,因为太过咸,不适合多方面使用。其余的还分散到空气中的水分,凝固在南北极的冰块等等。
所以,淡水在地球上占了少数。
用水时你可否想过了这一点?老实说,我也没有。
 
从网上看到5个不费力节省水的方法,参考以下:
  1. Install a low-flow showerhead. Save water and money, and still have ample water pressure, with a low-flow showerhead, which can slash bathing-water consumption 50 to 70 percent. The devices are simple to install and start at around $8. Many styles and features are available, including flow-adjusting dials and a pause button.
  2. Turn off the tap while you brush. Don’t let your water dollars — and one of nature’s most precious resources — run down the drain. Just turn off the water while you brush your teeth. The average bathroom faucet flows at a rate of two gallons a minute, according to the EPA’s WaterSense initiative. That means you’ll save up to 8 gallons of water a day per person.
  3. Water your yard in the morning. Reduce water waste and to promote healthy flora. Morning air is cooler, so less water is lost to evaporation than during the middle of the day. If you water in the evening, you run the risk of promoting fungi and bacterial diseases. 
  4. Use a Pro Car Wash. It may surprise you, but commercial car washes use water more efficiently, typically using 45 gallons of water per car. Home washers typically use between 80 and 140 gallons. Commercial car washes must also drain their wastewater into sewers, versus simply running it across your driveway into the land.
  5. Fix That Leak. Don’t ignore that dripping faucet or leaky pipe joint. One faulty faucet wastes 3 gallons of water per day, reports the U.S. Geological Survey. So get a pipe wrench and tighten those seals, replace old and worn hardware, and call your neighborhood plumber if you need help. Every drop really does add up.
