Question

 Everything you do leaves a   " carbon footprint"(碳足迹).For example, when you travel in a taxi, the car gives off(排放)C0₂ into the air. C0₂ 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 area

★  Drying clothes in a dryer produces a lot of C0₂.

★  If you use your dryer five times per week, you produce 185 kg of C0₂ per year.

★   Dry your clothes in the sun instead. Bathroom

★   If you take an eight-minute shower every day, you produce 616kg of C0₂ a year.

★   If you only use six minutes to take a shower, you can cut that number by 154 kg a year.
