Read the passage, then answer the questions that follow. A Stream for the Future On the edge of a small New Zealand town, a stream runs past a school and through a patch of native bush. In recent years, rubbish and muddy water had made the stream less healthy. Fewer small fish could be seen, and some stream insects had disappeared. A local group decided to help. They tested the water, collected litter and planted native grasses and shrubs along the banks. The plants helped hold the soil in place, so less mud washed into the water when it rained. The group also put up signs asking people not to leave rubbish beside the stream. The work did not change the stream overnight. Volunteers returned each season to check the plants and take another look at the water. Over time, the banks became greener and the water clearer. The group understood that caring for a place takes patience and teamwork. By looking after the stream now, people can help keep it healthy for those who will use and enjoy it in the future.
