At first their club only had 30 members , but word soon got around that Nature Madness was fun and less than a month later they had over 300 students . Now , they are thinking of asking for the of students from other schools .Nature Madness members took part in lost of after-school activities . They took classes to find out about pollution , recycling and conservation . The whole team helped to make the classes more interesting by using pictures and videos and so on . After that, the members organised different events and activities such as recycling or clean-up days,planting trees, and helping stray animals.The mayor gave each student a gold medal for their good work . Their teacher, Barbara Mac Alpine , said at the ceremony , "I'm very proud of my students . They show that you don't have to wait until you're grown up to do important things."
