【正确答案】　　Recently, with the rapid increase of automobiles in big cities of China, more and more people have become concerned about the problem of air pollution and energy consumption. Many people are worried that if we go on emitting tons of harmful gases and consuming huge quantities of energy, we will have to face serious air pollution and shortage of energy in the near future. Thus, it is the high time that we advocated low carbon living to protect our environment. To live a low carbon life, it is highly important for every one of us to take immediate actions to reduce the emission of co2.. First, public transportations such as buses and subways should be encouraged, and the number and use of private cars should be restricted, for all motorized travel is carbon-intensive and cheaper. Second, some energy conservation habits should be formed including using efficient light bulbs, switching off all appliances when you're not using them, and etc. Third, the use of disposable containers and plastic bags should be avoided. As far as I’m concerned, I’ll live a low carbon life in the following ways. For one thing, I’ll take stairs instead of lifts and ride to work whenever I can. For another, I’ll bring my own bag when I go shopping in the supermarkets. I strongly believe if everyone can do a little to reduce the emission of co2, all together, we’ll make a big difference.
