如果我们的地球在当天已经用完了本年度可再生的自然资源,进入了生态赤字状态,那么这一天就被称为“地球超载日”。1993年的地球超载日为10月22日,2003年提前到了9月20日,2013年又提前到了8月20日。如果再这样超载下去,人类生存的环境就会产生危机。怎样推迟地球超载日呢?节约能源,保护环境,让我们每个人都出一份力吧! If our planet had already run out of ecological deficit this year by using renewable natural resources this year, then this day will be called “Earth Overdraft Day.” The Earth’s overloading date of 1993 was October 22, ahead of September 2003 to September 20 and again to August 20 of 2013. If it goes on like this, the environment in which human beings survive will have a crisis. How to postpone the earth overdue? Save energy, protect the environment, let us all contribute!
