    A young man called Low­Carbon Brother become a hit on the Internet in 2011. He is still active in protecting the environment. He suggests living a low­carbon life, which means using less energy in our daily life so that we can help reducing carbon dioxide in the air. For example, she always picks up some waste paper on the street or uses the blank side to write something. While he is watching TV, he always turns up the screen brightness to the minimum and turns off the light. Therefore, he goes to work by bike instead of driving. Some people think what he is doing is just a show. No one can live such a simply life with so many modern invention around us. As far as I am concerned, I am strongly in support his idea and his behavior. Although what he is doing has no huge effect on global warming, but he at least can enjoy a healthy life.
