Luckily,we human beings have realized the problem. On April 22nd,millions of people across the world do something good for the earth. Some clean up beaches and water,some pick up rubbish,others give speeches to call on more people to take action. But can we save the earth only by one day‘s work? The future of our planet depends on our efforts. What we should do is to make every day Earth Day. Only by taking good care of it every day can we hope to live in harmony with nature.
