recently, my classmates and i participated in the activity of low – carbon living organized by the wwf. on the first day, we chose to go to school by bike or on foot rather than by bus or car. before we left the classroom, we made sure the lights and the computer were switched off. in order to make full use of paper, we began to write on both sides. besides, while shopping, we no longer used plastic bags but carried environmentally friendly ones. from joozone.com.
i think what we did on that day was meaningful, which an help us to form. a good habit. we should also call on the people around us to do something for low – carbon living. only in this way will the earth he a good place to live on.

each and every one of us is responsible for the greenhouse gases we emit in our daily actions and choices. therefore, combating climate change is going to take the combined efforts of everyone on the planet.
the average household carbon footprint in china is 2.41 tons of carbon dioxide annually. that‘s enough to fill half an olympic swimming pool.
surprised? well, here‘s how you can work to reduce it:
1.get started by calculating your own carbon footprint. this will give you a starting point from which to begin monitoring your progress. you enter details such as what sort of apartment you live in, your personal energy use and travel habits.
2. each week, choose one day when you don‘t eat meat. meat uses up lots of energy because it takes a long time to produce. animals produce methane, which is another dangerous greenhouse gas, when they burp and fart.
3. only buy the amount of food you need and if there are leftovers, get creative. for instance, make them into a soup. ask to take food home from restaurants if there‘s some left, but remember to take your own container to avoid using a disposable carton.

there are still many problems of environmental protection in recent years. one of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. the polluted water causes diseases and death. what is more, vegetation had been greatly reduced with the rapid growth of modern cities.
to protect the environment, governments of many countries have done a lot. legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. therefore, governments are playing the most important role in the environmental protection today. ad:from joozone.com.
in my opinion, to protect environment, the government must take even more concrete measures. first, it should let people fully realize the importance of environmental protection through education. second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. finally, those who destroy the environment intentionally should be severely punished. we should let them know that destroying environment means destroying mankind themselves
