7.Do you know everything that you do leaves a"carbon footprint(碳足迹)"?For example,when you travel in a taxi,the car gives off (排放)carbon dioxide (CO2)into the air.Carbon dioxide is a greenhouse gas(温室气体).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 C02 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 a week,you produce 185kg of CO2 a 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.

52.The more of CO2 we produce,the better environment we have.B.
