12．The problem of global warming has caused a lot of people to try their best to protect the environment．Unluckily，there are still many people who think it is hard to go green．In fact，it is very easy to be green in our daily life．
You can make a great start by learning to recycle （回收利用）．While this looks really simple，there are many people who still throw glass bottles into their common garbage．Almost all cities offer a recycling bin （垃圾箱） for these items．If you put them in the recycling bin instead of throwing them away，you will be on the path to save the earth．
One good thing to recycle is newspaper．But there are still some people who just put their newspaper in the garbage when they finish reading it．As we know，there are many other things we can do with an old newspaper．For example，we can use it to clean our windows．
Another thing that could help you to start to live green is to begin walking a bit more．Many people think nothing of getting in their car and driving one mile to get drinks at the local store．If you walk to the store，not only can it take less time，because you won't have to try to find a parking place，but you will be saving money on gas and helping to protect the environment．If you wish to save even more on gas，take the opportunity to car pool （拼车） each time you can，which has become popular in many countries．
There really are many means by which people can start living green．They only have to make some changes in their lifestyle to improve our environment．
