12．At present，too much carbon dioxide（二氧化碳） makes the earth warmer and causes terrible effect to human beings．To save our planet，to save ourselves，a new lifestyle called low-carbon life（低碳生活） becomes popular．Low carbon means low energy and no waste．It is necessary for everybody to learn to live a low-carbon life．
To live a low-carbon life，we'd better save energy as much as possible．Turn off the lights and TV whenever they are not needed．If possible，use cold water to wash clothes or dishes．Take a short shower and try to take a cold one when the weather gets warm．Don't do the cooking with electricity．
To live a low-carbon life，we should eat less meat．Everybody knows eating too much meat makes people fat and easy to have heart disease，but maybe you don't know keeping animals for food produces even more carbon dioxide than all the cars in the world，and being a vegetarian can help reduce（减少） one and a half ton（吨） of carbon dioxide a year．Maybe it is a little difficult，but it's really necessary．
To live a low-carbon life，we are supposed to do less shopping．When we go shopping，we may drive a car or take other transportations．On the one hand，these machines pollute the air and waste energy．On the other hand，most of us always buy some useless things because of some advertisements．It is not only a waste of money but also causes trouble to the earth，because as you know，making everything will produce carbon dioxide more or less．
There are many other ways to live a low-carbon life，such as recycling things，planting trees and reusing textbooks．If we can keep it a habit in our daily life，the earth will become a safer planet for us to live on．
