Natural wonders are very important, so we should protect them. First, we should not throw rubbish in places like forests, beaches or rivers. Instead, we need to put trash in the right bins and recycle when possible. Second, people should not cut down trees or harm animals because they are part of nature. We can also save water and electricity to reduce pollution. In addition, students can join activities like cleaning the environment or planting trees. The government should make strict rules to protect these places. If everyone works together, we can keep natural wonders clean, beautiful and safe for the future.
