Nowadays, environmental pollution is very common. Resource waste is also seen everywhere. In order to protect the environment, to protect our earth, we need to live a low-carbon life. I usually go to school on foot, sometimes by bike. If I need to go to the other city, I will choose the public transportation and not ask my parents drive me there. If I am the last one to leave classroom or home, I will make sure all the lights are off. I always will save the water after washing clothes. And then use it to wash the toilet. Our earth is in our own hands.
