It is of  importance for the whole world to practice the low-carbon lifestyle. Firstly, our natural resources and energy are limited; therefore, it is absolutely necessary for us to save and protect them. Secondly, in order to protect our environment from serious greenhouse effect, we need a low-carbon emission. It is low-carbon life that enables our next generations to live a better and superior life.

What we should bear in mind is that the earth is common home. Thus, every one is well advised to practice this lifestyle and there are several ways for us to do this. Firstly, every one is expected to be  aware of saving energy. Then, we are also hoped to help our families and friends to live a low-carbon life. Only by doing so can we hope to create a world where all humans enjoy a clean and tidy environment.
