My Lowcarbon Life
It's our duty to protect the environment.
As we all know, with the global warming and energy consumption, the environment is becoming worse and worse.It is very important for us to start with a lowcarbon lifestyle.But how can we live a low carbon life? Here are my ideas.
Firstly, it is a very good idea for us to go to school on foot instead of by car.It is good for the environment and our health as well.Secondly, remember to turn off the lights, fans and computers when we leave the classrooms.Thirdly, it is important for us to turn off the tap when we finish using the water.We can reuse water, too.For example, we can reuse the water to water the flowers or trees.At last, try to use the cloth shopping bags instead of plastic bags when we go shopping.(In addition, it is important for us to use fewer fast food boxes or chopsticks so that we can reduce the white pollution.)
I believe our life will become better and better if we can do these things.
Lower carbon, happier life.Let's take action.
