This book examines the methods and approaches currently being taken by the global community of youth in influencing environmental policymakers of the United Nations. It is divided into two sections: The Groundswell Approach, exploring the use of social media and mass gatherings aimed at raising public awareness of the issue of climate change; and The Direct Approach, a participatory methodology that encourages collaboration directly with the policymaker and youth in the discussions and creation of progressive climate policy for the world. The book also delivers a detailed analysis of the United Nations' only database of youth-produced documentary films related to climate change research, impacts, and proposed solutions: the Youth Climate Report, arguing that film is a powerful and effective communications tool for the policymaker. The book proposes two frameworks and explores their in-field applications for successful youth climate activism.
