How far do cultures affect the future of the planet? Can the debate on the environment and global warming be influenced by the cultures of East and West understanding each other better? In this consistently provocative dialogue, two of the most influential thinkers of recent times propose that only a 'human revolution' - a shift in the hearts and minds of individuals - can stimulate a revolution in humanity's relationship with the planet. Such a planetary revolution first requires a transformation of moral and political leadership, and an orientation towards the future rather than a preoccupation with the short-termist policies of the present. Responding to humanity's ills from the Buddhist perspective, and with all the accumulated wisdom of the eastern philosophical tradition, Daisaku Ikeda calls for politicians to take as their mainstays a respect for the dignity of life and an eloquence to inspire in people a sense of community and courage. Correspondingly, renowned western economist and scholar of education Ricardo Diez-Hochleitner stresses the importance of proper educational planning and development in addressing the challenges posed by poverty, inequality and climate change. While acknowledging the scale of the task that lies ahead, both men offer an inspiring and hopeful vision for the future.
