Sarah's notebook entry: May 23, 2011 As we all know, over the past years, natural disasters like earthquakes and storms have happened frequently on our plant. More and more people lost their lives and home , more and more children become homenss kids. people has some activty cause natural disasters have happened frequently. In my opinion, we should take an active part in saving Earth. For example, trees are very helpful and important for us. We should stop cutting down the trees, if there are not any trees, the Earth would get very hot. We should go to school by bus and bike instead of take a car with our parents. It's our duty to save water, As we know, water is very important to man. Let's try our best to protect our Earth. Let's join together to save our Earth.
