This is one of those websites which best exemplify the wonderful potential of sharing information through the Internet. The Green Map System was set up in 1995 to strengthen an awareness by communities of local urban ecology. There are 136 projects to date, including 20 completed by young people. Each map is created locally using shared icons and tools by mapmakers of all ages and backgrounds. Check if there is a greenmap of the city you intend to visit next.
