Cut the Carbon Footprint
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 185 kg 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.
