    Everything you do leaves a "carbon footprint" (碳足迹). For example, when you travel in a taxi, the car gives off CO2 into the air. CO2 is a greenhouse gas. Greenhouse gases make the earth become warm. To protect our environment, we need to leave less of a "carbon footprint". How big is your carbon footprint? To get an idea, take a look at the following numbers.
    Living areas
   . TV sets and DVD players produce 723kg of CO2 a year.
   . If you turn them off when you’re not using them, you can cut that number by 108kg.
    Laundry room (洗衣房)
    Drying clothes in a dryer produces a lot of CO2.
   . If you use your dryer five times per week, you produce 185kg of CO2 per year.
   . Dry your clothes in the sun instead.
    Bathroom
   . If you take an eight-minute shower every day, you produce 616kg of CO2 a year.
   . If you only use six minutes to take a shower, you can cut that number by 154kg a year.
CO2 is a greenhouse gas that can make the earth warm.
