Omaru stream

Hi there,I am going talk why we went to Omaru Stream. We are studying about streams. So then we went vist Omaru Stream to help it be healthy so the dragonflies come to lay their eggs ,when they lay it then they will change into a nypm that looks like an alien. But after they grow up they change into a beautiful dragonfly. Then find a mate so after it find a mate it makes baby so that where the life cycle stars over again. Also if  you want to know what a healthy stream looks like it must have dragonflies so then you will if is a healthy stream. oblivious of littering and if you litter you pollute the fish that in the stream and if the police sees that you litter you get a fine for littering.
