The more people,the more pollution.As one member of the earth,I must try to protect our home.I am not powerful,I can do my own thing,at least stop polluting and wastage.In my daily life,I go to work by bike.At home ,I turn off the appliances when I go out.For my rubbish,I recycle the paper and plastics.Maybe what I do are all little things,if everyone can do the same little thing,I believe we can save our home from now on.
