The seriousness of the ecological crisis that the planet is experiencing stimulates the creativity of authors and screenwriters, and pushes our thinkers and philosophers to decisively address the issues it raises. There is nothing new about the prospect of a probable end of humanity at a more or less distant moment in time. It will be remembered that the danger associated with the atomic bomb aroused a deep collective fear, especially in the 1960s.
While this fear has not yet completely disappeared, it has nevertheless been replaced by the prospect of a much slower but also more certain end. Yet the anxieties that this perspective provokes do not have a lesser impact on the collective psyche. How can we continue to hope in the future of humanity? Is it reasonable to hope for decisive action by political leaders and for the practical effectiveness of a collective and global awareness of the changes needed? Will humanity be capable of a profound conversion of its ways of life? What role can the Christian faith play in the future? How can the hope that this faith has always brought, even in times of catastrophe and great desolation, be translated into the concrete life of those who profess it?
