Kids and Ponds
Years ago there was a group of kids who would hang around at some local ponds in the woods near their houses in Warwick, Rhode Island. In summer they caught frogs and fish. When winter arrived they couldn't wait to go skating. Time passed, and the ponds became the only open space for the kids to enjoy themselves in that neighborhood.
One day. a thirteen-year-old boy from this group of kids read in the local newspaper that a developer wanted to fill in the ponds and build over a hundred small houses called condominiums. So the boy went door to door and gathered more than two hundred signatures (签名）to stop the development A group of citizens met and decided to support him.
At the meeting of the town planning board (委员会)，the boy was quite nervous at first and spoke very softly. But when he saw the faces of his friends and neighbors in the crowd and thought about what was happening to their favorite ponds，his voice grew louder. He told the town officials that they should speak for the citizens. He also insisted that they should leave enough space for children. A few days later，the developer stopped his plan.
Nine years later, when that teen was a senior in college, he was informed that the developer was back with his proposal to build condominiums. Now twenty-two years old, he was studying wetlands ecology. He again appeared before the town planning board. This time as an expert witness, he used environmental protection laws to explain restrictions on development in and around wetlands and the knowledge of wetlands ecology to help improve the development. Finally some condominiums were built, but less than half the number the developer wanted. The ponds where those kids used to hang around were protected by a strip of natural land，and are still there today.
