Climate change has devastating consequences for the future of humanity. In the 23rd century, a heatwave prevails. Only a new way of thinking and acting can provide relief. By the 23rd century, the world population has shrunk to a quarter due to the lack of climate protection from past generations and is severely traumatized. The rest of civilization ultimately embraces a value system that can better ensure the survival of humanity. Sara and Krishna Kumar, who live in Switzerland and Nepal, also suffer from the effects of global warming. Through this novel, Andreas Speich addresses the completely inadequate measures taken by humanity in the face of the already emerging climate change and seeks a solution to the associated global problems. In his opinion, reflecting on outdated moral concepts is necessary.
