The United Nations World Youth Report 2007 stated that there are approximately 1.2 billion people -- 18 per cent of the entire world population -- between the ages of fifteen and twenty-four living in the world. Youth is a powerful force for change and youth activism is on the rise, with a lot of young people taking action for social transformation. Youth are engaging with their communities and making their voices heard. This activism is being carried out through a variety of media and is conducted differently in nearly every country in the world. Young people can choose to hold rallies and protests on the streets, attend public hearings, or even organize grassroots movements within their communities. Since the Internet is used by 30 per cent of the world's population, as some estimates have it, it has also become a preferred tool for young people to foster positive change.
