1The goal here is to limit carbon dioxide and other greenhouse gases, which are closely associated to the big problem of global-warming. Strategy 1: Bring your own cup to Starbucks You’ll get a 10 cent discount, and it’s one less paper cup to end up in a landfill. While you’re there, pick up some free bags of spent coffee grounds to use as ‘‘green’’ fertilizer in your garden. The payoff: 2 Strategy2: Turn off your computer When in standby mode, your PC is still using energy. 3 The payoff: Turning off a monitor for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds Strategy 3: Reuse plastic bags Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag. The payoff: 4 The amount of oil it would take to make just 14 plastic bags would run your car for one mile. Strategy4: Use recycled paper in the bathroom Most of the toilet paper we use is made from trees found in forests previously untouched by humans. The payoff: If every household replaced one roll of toilet paper with a recycled one, 424000 trees would still be standing. Look for eco paper towels too. Strategy5: Buy energy-efficient appliances(电器)Replace the old fridge with an Energy Star appliance and you’ll use 15 percent less energy. 5 The payoff: If we all used one Energy Star appliance at home, it would be like planting 1. 7 million acres of new trees. |
