Do you know Earth Hour？ It usually falls on the last weekend of March every year. On that day， many families， malls and business buildings will turn off the lights from 8：30 pm to 9：30 pm of the local time. Earth Hour began in Sydney in 2007. Many homes and businesses kept their lights off for one hour. Now Earth Hour has become a worldwide event. It aims to tell us to care for our home， the earth.
Many famous buildings and homes in Chinese cities join the activity at 8：30 pm in March. They turned off the lights for Earth Hour.
Earth Hour is not only a message of hope but also a message of action. It's our duty to save the earth. Everyone can make a difference.
