Last year, Mark and his brother visited an exhibition named Go for a Change. The exhibition was a collection of photos of a group of children doing volunteer work to change their neighbourhood. Returning home, they decided to talk to some of their friends. Together they worked out a plan to help make their place greener and cleaner. They started by spending one hour every Sunday picking up litter and cleaning-up public places like the park and the church. They took care of the plants in the area and planted new ones. Last week, they finished a poster which called everybody in the community to act together for a better environment. Happily, their group is growing, from ten at the beginning to nearly thirty now. They believe that their activities will help make their neighbourhood a friendly place to live in.
