The little boy, frustrated, walked down the sidewalk. His backpack (背包) was heavy and his feet were slow. He stayed to his path, pausing every now and then only to pick out a new can or a slice of paper to kick as he went along his way. His heart felt as heavy as his backpack as he opened the door to his house and went inside.

His mother was in the kitchen, taking cookies out of the oven. She smiled as she turned around but stopped when she saw his face. "Tyier, what happened? Is everything okay?" "Nothing is okay, Mom. Nothing will ever be okay again." He stood in the middle of the kitchen as his mother came over to the kitchen table. "Sounds like you had a hard day, Tyier. Is there anything I can do to help?" "That's just the thing, Mom. We can't help. There's nothing we can do." He sat down at the table and put his head in his hands. His mother sat down and waited a moment until Tyier began to speak again.

"Today, in science class, the teacher was talking about Earth Day and the environment. Earth Day is supposed to be a day when every person promises to do something to help take care of our world. Mrs. Green was telling us how many companies are not careful about how they get rid of their industrial waste. She said that our world is getting dirtier and that many animals and plants are dying. She wants us to think of something we can do to help and I thought all the way home and there is nothing I can do. I can't stop the companies from polluting our air and water and I can't save all of the animals! There is not anything that I can do to make a difference."

His mother sat for a moment, thinking. "You sound like this really concerns you and that you have put a lot of thought into it, Tyier." Tyier nodded. "Let me tell you a story that your grandfather told me. I don't know where he heard it, but I think that it might help you think about your problem in a different way." She began, "One morning a man was walking down a beach that was covered with dying starfish (海星). The tide the night before had been especially strong and thousands of starfish had been washed up on shore, too far up for them to make it back into the water by themselves. The man shook his head as he walked along thinking what a shame it was that all of those starfish would die on the beach. He came upon a boy who was throwing starfish back into the ocean as fast as he could. He was out of breath and it was obvious that he had been at this task for a while. 'Son,' the man said, 'you might as well quit. There are thousands of them. They are washed up all over the beach as far as you can see. There is no way you can make any sort of a difference.' The boy did not even pause in what he was doing. He kept bending and throwing. But as he did, he spoke to the man, 'I can make a difference to this one, and this one, and this one.' The man thought, and he knew the boy was right. He began to help return the animals to their home, smiling at how life's biggest lessons sometimes came from the smallest people."

Tyier stared intently (专注地) at his mother. "But he did make a difference, didn't he? To every starfish that he threw back in?" His mother nodded, smiling. He sat for a moment, thinking about what his mother had said. "So, what it means is that even though I can't change everything, I can make a big difference by doing the little things that matter?" "That," she said, sliding him the plate of cookies, "is exactly what I am saying." Tyier smiled and took a cookie from the plate. "That gives me an idea." His mother smiled even bigger and said, "I kind of thought that it might work."

The next morning on the way to school, his feet hardly touched the ground. He told his teacher the story of the starfish and his idea. Mrs. Green thought it was a great idea, and decided to let Tyier share the story and his idea with the class. Everyone got to work immediately, cutting out large green leaves.

On Earth Day, there was an assembly and everyone in the community was invited. Many of those gathered were startled to see the large brown tree trunk affixed (粘贴) to the auditorium (礼堂) wall. They sat, puzzled, and waited for the program to begin. A boy, dressed up to look like a man, walked across a stage filled with starfish. The play went on as Tyier and his class telling the story and ended with the audience's applause.

"We were all thinking, and it was frustrating because we didn't think that we could do anything. The problems seemed too big for us to do anything about them. But we decided that together, even the little things we do could add up to mean a lot to our world."

The kids began passing out the green leaves and pens to the audience. "We want every person to think of one thing they can do that could make a difference to our world. Even if it seems like something small, it will matter." The audience began writing, and soon the tree was covered with the green leaves. Tyier and his class read many of them as they attached them to the tree. "I will walk to work." "I will use both sides of my paper to save trees." "I will have a puppy so there will be fewer puppies born without a home." "I will plant a tree every year." "I will start recycling my newspapers." Soon, the tree was beautiful and green and covered with the Earth Day promises. People were laughing and talking as they left, thinking of what they had promised to do.

When the dismissal (解散) bell rang, Tyier got his backpack and began the short walk home. As he reached the sidewalk, he pulled an old grocery bag from his backpack. He began picking up the trash as he made his way home, instead of kicking it. He smiled all the way, thinking of the difference he would make.
