New challenges arise all the time at the national and international level. Older generations often find it hard to adjust to these new challenges as their formative years were spent responding to other challenges that may no longer be relevant. It is up to the younger generation to insist that the agenda change to incorporate the new challenges, to push for new ideas to address these issues and to contribute to the new policies needed. Of all the new challenges the world currently faces, the gravest by far is climate change where young people have a vital role to play through encouraging a change of behaviour by governments, companies and households.
